Creatign new setting in userSettings section of app.config file

..NET 2 Winforms application.
How to create new setting and set it default value in userSettings section of app.config file or overwrite existing setting value ?

I found code below in this list which modifies Application setting section but how to add new item to userSettings ?

Andrus.


string sPath = Path.Combine(Environment.CurrentDirectory, "myapp.exe");
Configuration config = ConfigurationManager.OpenExeConfiguration(sPath);
// If your <appSettings> section doesn't contain "test_key" you should add it
config.AppSettings.Settings.Add("test_key", "test_value");
config.AppSettings.Settings["test_key"].Value = "test_value";
config.Save(ConfigurationSaveMode.Modified);
