在C#中如何讀寫INI文件

編輯：關於C語言

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

//讀ini文件（數字
[ DllImport ( "kernel32" ) ]
private static extern int GetPrivateProfileInt ( string section ,string key , int def , string filePath ) ;
