第一篇C#日志-ini读写

Posted 2022-11-14 menheger

首先创建一个类，我命名为IniFiles。需要引用命名空间using System.Runtime.InteropServices，System.IO;

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.InteropServices;

namespace WindowsFormsApplication1

public class IniFiles

public string inipath;

//声明API函数

[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
/// <summary>
/// 构造方法
/// </summary>
/// <param name="INIPath">文件路径</param>
public IniFiles(string INIPath)

inipath = INIPath;

public IniFiles()

/// <summary>
/// 写入INI文件
/// </summary>
/// <param name="Section">项目名称(如 [TypeName] )</param>
/// <param name="Key">键</param>
/// <param name="Value">值</param>
public void IniWriteValue(string Section, string Key, string Value)

WritePrivateProfileString(Section, Key, Value, this.inipath);

/// <summary>
/// 读出INI文件
/// </summary>
/// <param name="Section">项目名称(如 [TypeName] )</param>
/// <param name="Key">键</param>
public string IniReadValue(string Section, string Key)

StringBuilder temp = new StringBuilder(500);
int i = GetPrivateProfileString(Section, Key, "", temp, 500, this.inipath);
return temp.ToString();

/// <summary>
/// 验证文件是否存在
/// </summary>
/// <returns>布尔值</returns>
public bool ExistINIFile()

return File.Exists(inipath);

 

 

form1代码

 

namespace INI读写

public partial class Form1 : Form

IniFiles ini = new IniFiles(Application.StartupPath+@"\MyConfig.INI");
public Form1()

InitializeComponent();

private void Form1_Load(object sender, EventArgs e)

ini.IniWriteValue("登入详细", "用户名", "test");//写入数据
ini.IniWriteValue("登入详细", "中文账号", "password");//写入数据
if (ini.ExistINIFile())
this.Text = ini.IniReadValue("登入详细","中文账号");
