第一篇C#日志

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>文件路径</param>
public IniFiles(string INIPath)
{
inipath = INIPath;
}

public IniFiles() { }

/// <summary>
/// 写入INI文件
/// </summary>
/// <param>项目名称(如 [TypeName] )</param>
/// <param>键</param>
/// <param>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>项目名称(如 [TypeName] )</param>
/// <param>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([email protected]"\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");

}
}
}
