在 C#.NET 中如何读写 INI 文件

  
  //写INI文件
  [ DllImport ( "kernel32" ) ]
  private static extern bool WritePrivateProfileString ( string section ,string key , string val , string filePath ) ;
  //读ini文件(字符
  [ DllImport ( "kernel32" ) ]
  private static extern int GetPrivateProfileString ( string section ,string key , string def , StringBuilder retVal ,int size , string filePath ) ;
  
  //读ini文件(数字
  [ DllImport ( "kernel32" ) ]
  private static extern int GetPrivateProfileInt ( string section ,string key , int def , string filePath ) ;
