操作ini文件的公共类

以前我提供了一个操作ini文件的类，但是是VB.net版本。以下是我转载的一个C#版本的操作ini文件的类。

这里是一个通过调用Windows API来操作ini文件的一个公共类，并用托管代码进行了封装，提供了对ini文件的增删查改功能。

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

public class IniFiles
{
public delegate void EventHandler(object sender, EventArgs e);

public event EventHandler IniFileChanged;
public event EventHandler Initialization;
protected string IniFileName;

public string FileName
{
get
{
return IniFileName;
}
set
{
if (value != IniFileName)
{
IniFileName = value;
OnIniFileChanged(new EventArgs());
}
}
}
protected void OnIniFileChanged(EventArgs e)
{
if (IniFileChanged != null)
IniFileChanged(null, e);
}
protected void OnInitialization(EventArgs e)
{
if (Initialization != null)
Initialization(null, e);
}
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
/*
section: 要写入的段落名
key: 要写入的键，如果该key存在则覆盖写入
val: key所对应的值
filePath: INI文件的完整路径和文件名
*/

[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string defVal, System.Text.StringBuilder retVal, int size, string filePath);
/*
section：要读取的段落名
key: 要读取的键
defVal: 读取异常的情况下的缺省值
retVal: key所对应的值，如果该key不存在则返回空值
size: 值允许的大小
filePath: INI文件的完整路径和文件名
