[Setting]
ip=192.168.1.1
port=8080

代码示例：

using System;
using System.IO;
using read_write_ini;

namespace read_write_ini
{
public class Ini
{
// 声明INI文件的写操作函数 WritePrivateProfileString()

[System.Runtime.InteropServices.DllImport("kernel32")]

private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);

// 声明INI文件的读操作函数 GetPrivateProfileString()

[System.Runtime.InteropServices.DllImport("kernel32")]

private static extern int GetPrivateProfileString(string section, string key, string def, System.Text.StringBuilder retVal, int size, string filePath);

private string sPath = null;
public Ini(string path)
{
this.sPath = path;
}

public void Writue(string section, string key, string value)
{

// section=配置节，key=键名，value=键值，path=路径

WritePrivateProfileString(section, key, value, sPath);

}
public string ReadValue(string section, string key)
{

// 每次从ini中读取多少字节

System.Text.StringBuilder temp = new System.Text.StringBuilder(255);

// section=配置节，key=键名，temp=上面，读取该键名的值最大长度，path=路径

GetPrivateProfileString(section, key, "", temp, 255, sPath);

return temp.ToString();

}
}
}

class Program
{
static void Main(string[] args)
{
string Current;

Current = Directory.GetCurrentDirectory();//获取当前根目录
Console.WriteLine("Current directory {0}", Current);
// 写入ini
Ini ini = new Ini(Current + "/config.ini");
//ini.Writue("Setting", "key1", "key1 value");
//ini.Writue("Setting", "key2", "key2 value");
//ini.Writue("SettingImg", "Path", "IMG.Path");
// 读取ini
string stemp = ini.ReadValue("Setting", "ip");
Console.WriteLine(stemp);
Console.ReadKey();
}
}
