C# 使用Hashtable处理Ini文件

本人初学C#，未找到处理Ini文件的标准类，自己动手结合Hashtable写了一个。发布出来，与大家一起探讨，如果知道有其它更好的办法，麻烦通知我一下。

写INI文件

            IniFile iniFile = new IniFile("C://1.ini");
            iniFile.WriteString("A","A1","1");
            iniFile.WriteString("A", "A2", "2");
            iniFile.WriteString("A", "A3", "3");
            iniFile.WriteString("B", "B1", "11");
            iniFile.WriteString("B", "B2", "12");
            iniFile.WriteString("A", "A4", "4");
            iniFile.Save();

 

读INI文件

           IniFile iniFile = new IniFile("C://1.ini");
           textBox3.Text=  iniFile.ReadString("A","A2""");
