在目录中搜索特定文件名

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了在目录中搜索特定文件名相关的知识,希望对你有一定的参考价值。
我正在尝试在系统上的所有卷上搜索特定文件名,但系统卷信息或Windows目录除外,并打印出每个文件的每个完整路径。
我试过使用Directory.GetFiles
,但它只在驱动器C:或驱动器D:中搜索(取决于指定的驱动器)
我怎样才能实现目标?
例如,我想运行程序并搜索名为“.DS_Store”的文件(用于使用mac,现在我的文件系统已经满了这些文件......)
我真的很感激任何帮助。先感谢您
UPD。程序应该使用管理员权限执行
答案
作为密码锁分析的一部分,我编写了一个定位目标扩展的原型,以下是如何使用它
var cmd = new LocateTargetFilesCommand();
cmd.Execute()
它将搜索所有驱动器的两个扩展:.xlsx
和.doc
。最大的问题是处理权限问题。子文件夹也可能具有更宽的权限,因此如果您无法访问父文件夹,您仍然可以访问其根目录。
最后,cmd.FoundTargets
将包含具有所需扩展名的找到文件的绝对路径
public class LocateTargetFilesCommand
{
private string[] _targetExtensions = new[]
{
"xlsx", "doc"
};
public LocateTargetFilesCommand()
{
FoundTargets = new ConcurrentQueue<string>();
DirsToSearch = new List<string>();
}
public ConcurrentQueue<string> FoundTargets { get; private set; }
public List<string> DirsToSearch { get; private set; }
public void Execute()
{
DriveInfo[] driveInfos = DriveInfo.GetDrives();
Console.WriteLine("Start searching");
foreach (var driveInfo in driveInfos)
{
if (!driveInfo.IsReady)
continue;
Console.WriteLine("Locating directories for drive: " + driveInfo.RootDirectory);
GetAllDirs(driveInfo.RootDirectory.ToString());
Console.WriteLine("Found {0} folders", DirsToSearch.Count);
foreach (var ext in _targetExtensions)
{
Console.WriteLine("Searching for .*" + ext);
int currentNotificationProgress = 0;
for (int i = 0; i < DirsToSearch.Count; i++)
{
int progressPercentage = (i * 100) / DirsToSearch.Count;
if (progressPercentage != 0)
{
if (progressPercentage % 10 == 0 && currentNotificationProgress != progressPercentage)
{
Console.WriteLine("Completed {0}%", progressPercentage);
currentNotificationProgress = progressPercentage;
}
}
var dir = DirsToSearch[i];
try
{
string[] files = Directory.GetFiles(dir, "*." + ext, SearchOption.TopDirectoryOnly);
foreach (var file in files)
{
FoundTargets.Enqueue(file);
}
}
catch (UnauthorizedAccessException ex)
{
Console.WriteLine("Skipping directory: {0}", dir);
DirsToSearch.Remove(dir);
}
}
Console.WriteLine("So far located {0} targets", FoundTargets.Count);
}
DirsToSearch.Clear();
}
Console.WriteLine("Stop searching");
}
public void GetAllDirs(string root)
{
try
{
string[] dirs = Directory.GetDirectories(root);
DirsToSearch.AddRange(dirs);
foreach (var dir in dirs)
{
GetAllDirs(dir);
}
}
catch (UnauthorizedAccessException)
{
//swallow
}
}
}
另一答案
foreach (var d in Directory.GetLogicalDrives())
{
var files = Directory.GetFiles(d, file);
}
另一答案
试试这个:
foreach (var drive in Directory.GetLogicalDrives())
{
foreach (var fileInfo in from dir in Directory.GetDirectories(drive) from file in Directory.GetFiles(dir) select new FileInfo(file))
{
// get all details in fileInfo
}
}
另一答案
感谢oleksii,但这是我如何使用此代码排除所有系统目录:
public class LocateTargetFilesCommand
{
private string[] _targetExtensions = new[]
{
".DS_Store"
};
public LocateTargetFilesCommand()
{
FoundTargets = new ConcurrentQueue<string>();
DirsToSearch = new List<string>();
}
public ConcurrentQueue<string> FoundTargets { get; private set; }
public List<string> DirsToSearch { get; private set; }
public void Execute()
{
DriveInfo[] driveInfos = DriveInfo.GetDrives();
Console.WriteLine("Start searching");
foreach (var driveInfo in driveInfos)
{
if (!driveInfo.IsReady)
continue;
Console.WriteLine("Locating directories for drive: " + driveInfo.RootDirectory);
GetAllDirs(driveInfo.RootDirectory.ToString());
Console.WriteLine("Found {0} folders", DirsToSearch.Count);
foreach (var ext in _targetExtensions)
{
Console.WriteLine("Searching for " + ext);
int currentNotificationProgress = 0;
for (int i = 0; i < DirsToSearch.Count; i++)
{
int progressPercentage = (i * 100) / DirsToSearch.Count;
if (progressPercentage != 0)
{
if (progressPercentage % 10 == 0 && currentNotificationProgress != progressPercentage)
{
Console.WriteLine("Completed {0}%", progressPercentage);
currentNotificationProgress = progressPercentage;
}
}
var dir = DirsToSearch[i];
try
{
string[] files = Directory.GetFiles(dir, ext, SearchOption.TopDirectoryOnly);
foreach (var file in files)
{
FoundTargets.Enqueue(file);
}
}
catch (UnauthorizedAccessException ex)
{
Console.WriteLine("Skipping directory: {0}", dir);
DirsToSearch.Remove(dir);
}
}
Console.WriteLine("So far located {0} targets", FoundTargets.Count);
}
DirsToSearch.Clear();
}
Console.WriteLine("Stop searching");
}
public void GetAllDirs(string root)
{
try
{
string[] dirs = Directory.GetDirectories(root);
DirsToSearch.AddRange(dirs);
foreach (var dir in dirs)
{
if(dir.Contains("Windows"))
Console.WriteLine("Skipped Windows Directory");
else if (dir.Contains("Users"))
Console.WriteLine("Skipped Users Directory");
else if (dir.Contains("MSOCache"))
Console.WriteLine("Skipped MSOCache Directory");
else if (dir.Contains("SYSTEM.SAV"))
Console.WriteLine("Skipped SYSTEM.SAV Directory");
else if (dir.Contains("ProgramData"))
Console.WriteLine("Skipped ProgramData Directory");
else if (dir.Contains("System Volume Information"))
Console.WriteLine("Skipped System Volume Information Directory");
else if (dir.Contains("$SysReset"))
Console.WriteLine("Skipped $SysReset Directory");
else
GetAllDirs(dir);
}
}
catch (UnauthorizedAccessException)
{
}
}
}
