如何在C#中读写INI文件？

Question

建议用xml文件，但提供INI的类 /// <summary>
/// Ini文件操作的类
/// </summary>
public class IniFile
{
public string path;     //INI文件名 //声明读写INI文件的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>
/// 类的构造函数
/// </summary>
/// <param name="INIPath">INI文件名</param>
public IniFile(string INIPath)
{
path = INIPath;
} /// <summary>
/// 写INI文件 
/// </summary>
/// <param name="Section">节</param>
/// <param name="Key">关键字</param>
/// <param name="Value">值</param>
public void WriteValue(string Section,string Key,string Value)
{
WritePrivateProfileString(Section,Key,Value,this.path);
}
/// <summary>
/// 写INI文件 
/// </summary>
/// <param name="Section">节</param>
/// <param name="Key">关键字</param>
/// <param name="Value">值</param>
/// <param name="path">ini文件所以路径</param>
public static void WriteValue(string Section,string Key,string Value,string path)
{
WritePrivateProfileString(Section,Key,Value,path);
}
/// <summary>
/// 读取INI文件指定
/// </summary>
/// <param name="Section">节</param>
/// <param name="Key">关键字</param>
/// <returns>指定节-关键字的值</returns>
public string ReadValue(string Section,string Key)
{
StringBuilder temp = new StringBuilder(255);
int i = GetPrivateProfileString(Section,Key,"",temp,255,this.path);
return temp.ToString();
} /// <summary>

/// </summary>
/// <param name="Section">节</param>

/// <returns>指定节-关键字的值</returns>

public string ReadValue(string Section,string Key,string path)
{
StringBuilder temp = new StringBuilder(255);
