The easiest way to read/write AppSettings config file there is a special section in reserved which allows you to do exactly that. Simply add an <appsettings> section and add your data as key/value pairs of the form <add key="xxx" value="xxxx" /> . That's all to create a new app. config file with settings in it.
Add the App. config file to your project. After creating a . NET Framework project, right-click on your project in Solution Explorer and choose Add > New Item. Choose the Application Configuration File item and then select Add.
Try the following code:
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath); config.AppSettings.Settings.Add("YourKey", "YourValue"); config.Save(ConfigurationSaveMode.Minimal); It worked for me :-)
