ini文件写入

INIFile ab = new INIFile(@"D:\project\WebApplication9\Token");
                string iniFile = @"D:\project\WebApplication9\Token\Token.ini";
                if (!File.Exists(iniFile))
                {
                    using (FileStream fs = File.Create(iniFile))
                    {
                        fs.Close();
                    }
                }

                INIFile myINI = new INIFile(iniFile);

                myINI.IniWriteValue("User", T_USER .Text, T_PW.Text);

ini文件读取

INIFile ab = new INIFile(@"D:\project\WebApplication9\Token\Token.ini");
               pw = ab.IniReadValue("User", T_USER.Text );
