C # Read and write to INI file

C # itself does not have an operation class for the INI format file, and can customize a Inifile class to read and write INI files.

Application:

There are original INI files:

Execute code:

IniFile Myini =NewIniFile (Environment.currentdirectory +"\\Config.ini"); Myini.writeint ("tsection","Tname", the); Console.WriteLine (Myini.readstring ("System","Mainformname","")); Console.WriteLine (Myini.readstring ("DBServer","DBFile","")); Myini.writestring ("DBServer","DBFile",@"E:\Work\test2.db"); Console.WriteLine (Myini.readstring ("DBServer","DBServer","")); Console.WriteLine (Myini.readstring ("DBServer","DBFile",""));
