本文介绍了一个使用C#实现的INI文件读写类RWIni。该类提供了读取和写入INI文件中整型及字符串数据的功能，并支持删除特定键值或整个节。通过调用kernel32.dll中的API函数完成操作。

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
using Microsoft.Win32;

namespace Wjb.ReadOrWriteIniAndReg
{
///
/// RWIni 的摘要说明。
/// 读写ini文件类
/// 功能：读写INI文件
///
public class RWIni
{
private static string FileName;

[DllImport("kernel32")]
private static extern int GetPrivateProfileInt(
string lpAppName,
string lpKeyName,
int nDefault,
string lpFileName
);
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(
string lpAppName,
string lpKeyName,
string lpDefault,
StringBuilder lpReturnedString,
int nSize,
string lpFileName
);
[DllImport("kernel32")]
private static extern bool WritePrivateProfileString(
string lpAppName,
string lpKeyName,
string lpString,
string lpFileName
);
