篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了C# 文件操作相关的知识,希望对你有一定的参考价值。

1.创建文件夹

//using System.IO;
Directory.CreateDirectory(%%1);
2.创建文件
//using System.IO;
File.Create(%%1);
3.删除文件
//using System.IO;
File.Delete(%%1);
4.删除文件夹
//using System.IO;
Directory.Delete(%%1);
5.删除一个目录下所有的文件夹
//using System.IO;
foreach (string dirStr in Directory.GetDirectories(%%1))
{
 DirectoryInfo dir = new DirectoryInfo(dirStr);
 ArrayList folders=new ArrayList();
 FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
 for (int i = 0; i < folders.Count; i++)
 {
  FileInfo f = folders[i] as FileInfo;
  if (f == null)
  {
   DirectoryInfo d = folders[i] as DirectoryInfo;
   d.Delete();
  }
 }
}
6.清空文件夹
//using System.IO;
Directory.Delete(%%1,true);
Directory.CreateDirectory(%%1);
7.读取文件
//using System.IO;
StreamReader s = File.OpenText(%%1);
string %%2 = null;
while ((%%2 = s.ReadLine()) != null){
 %%3
}
s.Close();
8.写入文件
//using System.IO;
FileInfo f = new FileInfo(%%1);
StreamWriter w = f.CreateText();
w.WriteLine(%%2);
w.Close();
9.写入随机文件
//using System.IO;
byte[] dataArray = new byte[100000];//new Random().NextBytes(dataArray);
using(FileStream FileStream = new FileStream(%%1, FileMode.Create)){
// Write the data to the file, byte by byte.
 for(int i = 0; i < dataArray.Length; i++){
  FileStream.WriteByte(dataArray[i]);
 }
// Set the stream position to the beginning of the file.
 FileStream.Seek(0, SeekOrigin.Begin);
// Read and verify the data.
 for(int i = 0; i < FileStream.Length; i++){
  if(dataArray[i] != FileStream.ReadByte()){
   //写入数据错误
   return;
  }
 }
//"数据流"+FileStream.Name+"已验证"
}
10.读取文件属性
//using System.IO;
FileInfo f = new FileInfo(%%1);//f.CreationTime,f.FullName
if((f.Attributes & FileAttributes.ReadOnly) != 0){
 %%2
}
else{
 %%3
}
11.写入属性
//using System.IO;
FileInfo f = new FileInfo(%%1);
//设置只读
f.Attributes = myFile.Attributes | FileAttributes.ReadOnly;
//设置可写
f.Attributes = myFile.Attributes & ~FileAttributes.ReadOnly;
12.枚举一个文件夹中的所有文件夹
//using System.IO;
foreach (string %%2 in Directory.GetDirectories(%%1)){
 %%3
}
/*
DirectoryInfo dir = new DirectoryInfo(%%1);
FileInfo[] files = dir.GetFiles("*.*");
foreach(FileInfo %%2 in files){
 %%3
}
*/
13.复制文件夹
/*
using System.IO;
using System.Collections;
*/
string path = (%%2.LastIndexOf("\") == %%2.Length - 1) ? %%2 : %%2+"\";
string parent = Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path + Path.GetFileName(%%1));
DirectoryInfo dir = new DirectoryInfo((%%1.LastIndexOf("\") == %%1.Length - 1) ? %%1 : %%1 + "\");
FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count>0)
{
                    FileSystemInfo tmp = Folders.Dequeue();
                    FileInfo f = tmp as FileInfo;
                    if (f == null)
                    {
                        DirectoryInfo d = tmp as DirectoryInfo;
                        Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("\") == parent.Length - 1) ? parent : parent + "\", path));
                        foreach (FileSystemInfo fi in d.GetFileSystemInfos())
                        {
                            Folders.Enqueue(fi);
                        }
                    }
                    else
                    {
                        f.CopyTo(f.FullName.Replace(parent, path));
                    }
}
14.复制目录下所有的文件夹到另一个文件夹下
/*
using System.IO;
using System.Collections;
*/
DirectoryInfo d = new DirectoryInfo(%%1);
foreach (DirectoryInfo dirs in d.GetDirectories())
{
    Queue<FileSystemInfo> al = new Queue<FileSystemInfo>(dirs.GetFileSystemInfos());
    while (al.Count > 0)
    {
        FileSystemInfo temp = al.Dequeue();
        FileInfo file = temp as FileInfo;
        if (file == null)
        {
            DirectoryInfo directory = temp as DirectoryInfo;
            Directory.CreateDirectory(path + directory.Name);
            foreach (FileSystemInfo fsi in directory.GetFileSystemInfos())
                al.Enqueue(fsi);
        }
        else
            File.Copy(file.FullName, path + file.Name);
    }
}
15.移动文件夹
/*
using System.IO;
using System.Collections;
*/
                string filename = Path.GetFileName(%%1);
                string path=(%%2.LastIndexOf("\") == %%2.Length - 1) ? %%2 : %%2 + "\";
                if (Path.GetPathRoot(%%1) == Path.GetPathRoot(%%2))
                    Directory.Move(%%1, path + filename);
                else
                {
                    string parent = Path.GetDirectoryName(%%1);
                    Directory.CreateDirectory(path + Path.GetFileName(%%1));
                    DirectoryInfo dir = new DirectoryInfo((%%1.LastIndexOf("\") == %%1.Length - 1) ? %%1 : %%1 + "\");
                    FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
                    Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
                    while (Folders.Count > 0)
                    {
                        FileSystemInfo tmp = Folders.Dequeue();
                        FileInfo f = tmp as FileInfo;
                        if (f == null)
                        {
                            DirectoryInfo d = tmp as DirectoryInfo;
                            DirectoryInfo dpath = new DirectoryInfo(d.FullName.Replace((parent.LastIndexOf("\") == parent.Length - 1) ? parent : parent + "\", path));
                            dpath.Create();
                            foreach (FileSystemInfo fi in d.GetFileSystemInfos())
                            {
                                Folders.Enqueue(fi);
                            }
                        }
                        else
                        {
                            f.MoveTo(f.FullName.Replace(parent, path));
                        }
                    }
                    Directory.Delete(%%1, true);
                }
16.移动目录下所有的文件夹到另一个目录下
/*
using System.IO;
using System.Collections;
*/
string filename = Path.GetFileName(%%1);
                if (Path.GetPathRoot(%%1) == Path.GetPathRoot(%%2))
                    foreach (string dir in Directory.GetDirectories(%%1))
                        Directory.Move(dir, Path.Combine(%%2,filename));
                else
                {
                    foreach (string dir2 in Directory.GetDirectories(%%1))
                    {
                        string parent = Path.GetDirectoryName(dir2);
                        Directory.CreateDirectory(Path.Combine(%%2, Path.GetFileName(dir2)));
                        string dir = (dir2.LastIndexOf("\") == dir2.Length - 1) ? dir2 : dir2 + "\";
                        DirectoryInfo dirdir = new DirectoryInfo(dir);
                        FileSystemInfo[] fileArr = dirdir.GetFileSystemInfos();
                        Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dirdir.GetFileSystemInfos());
                        while (Folders.Count > 0)
                        {
                            FileSystemInfo tmp = Folders.Dequeue();
                            FileInfo f = tmp as FileInfo;
                            if (f == null)
                            {
                                DirectoryInfo d = tmp as DirectoryInfo;
                                DirectoryInfo dpath = new DirectoryInfo(d.FullName.Replace((parent.LastIndexOf("\") == parent.Length - 1) ? parent : parent + "\", %%2));
                                dpath.Create();
                                foreach (FileSystemInfo fi in d.GetFileSystemInfos())
                                {
                                    Folders.Enqueue(fi);
                                }
                            }
                            else
                            {
                                f.MoveTo(f.FullName.Replace(parent, %%2));
                            }
                        }
                        dirdir.Delete(true);
                    }
                }
17.以一个文件夹的框架在另一个目录创建文件夹和空文件
/*
using System.IO;
using System.Collections;
*/
bool b=false;
string path = (%%2.LastIndexOf("\") == %%2.Length - 1) ? %%2 : %%2 + "\";
string parent = Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path + Path.GetFileName(%%1));
DirectoryInfo dir = new DirectoryInfo((%%1.LastIndexOf("\") == %%1.Length - 1) ? %%1 : %%1 + "\");
FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count > 0)
{
    FileSystemInfo tmp = Folders.Dequeue();
    FileInfo f = tmp as FileInfo;
    if (f == null)
    {
        DirectoryInfo d = tmp as DirectoryInfo;
        Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("\") == parent.Length - 1) ? parent : parent + "\", path));
        foreach (FileSystemInfo fi in d.GetFileSystemInfos())
        {
            Folders.Enqueue(fi);
        }
    }
    else
    {
        if(b) File.Create(f.FullName.Replace(parent, path));
    }
}
18.复制文件
//using System.IO;
File.Copy(%%1,%%2);
19.复制一个文件夹下所有的文件到另一个目录
//using System.IO;
foreach (string fileStr in Directory.GetFiles(%%1))
 File.Copy((%%1.LastIndexOf("\") == %%1.Length - 1) ? %%1 +Path.GetFileName(fileStr): %%1 + "file://"+Path.GetFileName(fileStr),(%%2.LastIndexOf("//") == %%2.Length - 1) ? %%2 +Path.GetFileName(fileStr): %%2 + "file://"+Path.GetFileName(fileStr/));
20.提取扩展名
//using System.IO;
string %%2=Path.GetExtension(%%1);
21.提取文件名
//using System.IO;
string %%2=Path.GetFileName(%%1);
22.提取文件路径
//using System.IO;
string %%2=Path.GetDirectoryName(%%1);
23.替换扩展名
//using System.IO;
File.ChangeExtension(%%1,%%2);
24.追加路径
//using System.IO;
string %%3=Path.Combine(%%1,%%2);
25.移动文件
//using System.IO;
File.Move(%%1,%%2+"file://"+file.getname(%%1/));
26.移动一个文件夹下所有文件到另一个目录
foreach (string fileStr in Directory.GetFiles(%%1))
 File.Move((%%1.LastIndexOf("\") == %%1.Length - 1) ? %%1 +Path.GetFileName(fileStr): %%1 + "file://"+Path.GetFileName(fileStr),(%%2.LastIndexOf("//") == %%2.Length - 1) ? %%2 +Path.GetFileName(fileStr): %%2 + "file://"+Path.GetFileName(fileStr/));
27.指定目录下搜索文件
/*
using System.Text;
using System.IO;
*/
string fileName=%%1;
string dirName=%%2;
 DirectoryInfo   dirc=new   DirectoryInfo(dirName);
 foreach(FileInfo   file   in   dirc.GetFiles()) {
  if(file.Name.IndexOf(fileName)>-1)
   return file.FullName;
  }
  foreach(DirectoryInfo   dir   in   dirc.GetDirectories())   {  
   return   GetFile(fileName,dir.FullName);  
  }
  return   "找不到指定的文件";  
 }
28.打开对话框
OpenFileDialog penFileDialog=new OpenFileDialog();
openFileDialog.InitialDirectory="c:\\";//注意这里写路径时要用c:\\而不是c:\
openFileDialog.Filter="文本文件|*.*|C#文件|*.cs|所有文件|*.*";
openFileDialog.RestoreDirectory=true;
openFileDialog.FilterIndex=1;
if (openFileDialog.ShowDialog()==DialogResult.OK) {
 fName=openFileDialog.FileName;
 File fileOpen=new File(fName);
 isFileHaveName=true;
 %%1=fileOpen.ReadFile();
 %%1.AppendText("");
}
29.文件分割
//using System.IO;
FileStream fsr = new FileStream(%%1, FileMode.Open, FileAccess.Read);
byte[] btArr = new byte[fsr.Length];
fsr.Read(btArr, 0, btArr.Length);
fsr.Close();
string strFileName=%%1.Substring(%%1.LastIndexOf("file://")+1/);
FileStream fsw = new FileStream(%%2 + strFileName + "1", FileMode.Create, FileAccess.Write);
fsw.Write(btArr, 0, btArr.Length/2);
fsw.Close();
fsw = new FileStream(%%2 + strFileName + "2", FileMode.Create, FileAccess.Write);
fsw.Write(btArr, btArr.Length/2, btArr.Length-btArr.Length/2);
fsw.Close();
30.文件合并
//using System.IO;
string strFileName = %%1.Substring(%%1.LastIndexOf("\") + 1);
FileStream fsr1 = new FileStream(%%2 + strFileName + "1", FileMode.Open, FileAccess.Read);
FileStream fsr2 = new FileStream(%%2 + strFileName + "2", FileMode.Open, FileAccess.Read);
byte[] btArr = new byte[fsr1.Length+fsr2.Length];
fsr1.Read(btArr, 0, Convert.ToInt32(fsr1.Length));
fsr2.Read(btArr, Convert.ToInt32(fsr1.Length), Convert.ToInt32(fsr2.Length));
fsr1.Close();fsr2.Close();
FileStream fsw = new FileStream(%%2 + strFileName, FileMode.Create, FileAccess.Write);
fsw.Write(btArr, 0, btArr.Length);
fsw.Close();
31.文件简单加密
//using System.IO;
//读文件
FileStream fsr = new FileStream(%%1, FileMode.Open, FileAccess.Read);
byte[] btArr = new byte[fsr.Length];
fsr.Read(btArr, 0, btArr.Length);
fsr.Close();
for (int i = 0; i < btArr.Length; i++){ //加密
 int ibt = btArr[i];
 ibt += 100;
 ibt %= 256;
 btArr[i] = Convert.ToByte(ibt);
}
//写文件
string strFileName = Path.GetExtension(%%1);
FileStream fsw = new FileStream(%%2+"/" + "enc_" + strFileName, FileMode.Create, FileAccess.Write);
 fsw.Write(btArr, 0, btArr.Length);
 fsw.Close();
32.文件简单解密
//using System.IO;
FileStream fsr = new FileStream(%%1, FileMode.Open, FileAccess.Read);
byte[] btArr = new byte[fsr.Length];
fsr.Read(btArr, 0, btArr.Length);
fsr.Close();
for (int i = 0; i < btArr.Length; i++){ //解密
 int ibt = btArr[i];
 ibt -= 100;
 ibt += 256;
 ibt %= 256;
 btArr[i] = Convert.ToByte(ibt);
}
//写文件
string strFileName = Path.GetExtension(%%1);
FileStream fsw = new FileStream(%%2 +"/" + strFileName, FileMode.Create, FileAccess.Write);
fsw.Write(btArr, 0, btArr.Length);
fsw.Close();
33.读取ini文件属性
//using System.Runtime.InteropServices;
//[DllImport("kernel32")]//返回取得字符串缓冲区的长度
//private static extern long GetPrivateProfileString(string section,string key, string def,StringBuilder retVal,int size,string filePath);
string Section=%%1;
string Key=%%2;
string NoText=%%3;
string iniFilePath="Setup.ini";
string %%4=String.Empty;
 if(File.Exists(iniFilePath)){
  StringBuilder temp = new StringBuilder(1024);
  GetPrivateProfileString(Section,Key,NoText,temp,1024,iniFilePath);
  %%4=temp.ToString();
 }
34.合并一个目录下所有的文件
//using System.IO;
FileStream fsw = new FileStream(%%2, FileMode.Create, FileAccess.Write);
foreach (string fileStr in Directory.GetFiles(%%1))
{
FileStream fsr1 = new FileStream(fileStr, FileMode.Open, FileAccess.Read);
byte[] btArr = new byte[fsr1.Length];
fsr1.Read(btArr, 0, Convert.ToInt32(fsr1.Length));
fsr1.Close();
fsw.Write(btArr, 0, btArr.Length);
}
fsw.Close();
35.写入ini文件属性
//using System.Runtime.InteropServices;
//[DllImport("kernel32")]//返回0表示失败,非0为成功
//private static extern long WritePrivateProfileString(string section,string key, string val,string filePath);
string Section=%%1;
string Key=%%2;
string Value=%%3;
string iniFilePath="Setup.ini";
bool %%4=false;
    if(File.Exists(iniFilePath))
    {
long pStation = WritePrivateProfileString(Section,Key,Value,iniFilePath);   
if(OpStation == 0)
{
    %%4=false;
}
else
{
    %%4=true;
}
    }
36.获得当前路径
string %%1=Environment.CurrentDirectory;
37.读取XML数据库
//using System.Xml;
XmlDocument doc=new XmlDocument();
doc.Load(%%1);
string %%9;
XmlElement xe=doc.GetElementById(%%7);
XmlNodeList elemList=xe.ChildNodes;
foreach(XmlNode elem in elemList)
{
if(elem.NodeType==%%8)
{
%%9=elem.Value;
break;
}
}
38.写入XML数据库
//using System.Xml;
XmlDocument doc=new XmlDocument();
doc.Load(%%1);
XmlNode root=doc.DocumentElement;
XmlElement book=doc.CreateElement(%%3);
XmlElement book=doc.CreateElement(%%5);
XmlElement port=doc.CreateElement(%%6);
book.SetAttribute(%%4,root.ChildNodes.Count.ToString());
author.InnerText=%%8;
book.appendChild(author);
book.appendChild(port);
root.appendChild(book);
doc.Save(%%1);

//Traditionally grep stands for "Global Regular Expression Print".
//Global means that an entire file is searched.
//Regular Expression means that a regular expression string is used to establish a search pattern.
//Print means that the command will display its findings.
//Simply put, grep searches an entire file for the pattern you want and displays its findings.
//
//The use syntax is different from the traditional Unix syntax, I prefer a syntax similar to
//csc, the C# compiler.
//
// grep [/h|/H] - Usage Help
//
// grep [/c] [/i] [/l] [/n] [/r] /E:reg_exp /F:files
//
// /c - print a count of matching lines for each input file;
// /i - ignore case in pattern;
// /l - print just files (scanning will stop on first match);
// /n - prefix each line of output with line number;
// /r - recursive search in subdirectories;
//
// /E:reg_exp - the Regular Expression used as search pattern. The Regular Expression can be delimited by
// quotes like "..." and ‘...‘ if you want to include in it leading or trailing blanks;
//
// /F:files - the list of input files. The files can be separated by commas as in /F:file1,file2,file3
//and wildcards can be used for their specification as in /F:*file?.txt;
//
//Example:
//
// grep /c /n /r /E:" C Sharp " /F:*.cs
