Since it's a web application you want to change I'd go with the WebConfigurationManager.

If the configuration value you are about to change is in a separate section you need to get that section first:

var myConfiguration = (Configuration)WebConfigurationManager.OpenWebConfiguration("~");
var section = (MySectionTypeHere)myConfiguration.GetSection("system.web/mySectionName");
//Change your settings here
myConfiguration.Save();

Keep in mind that the web application will be restarted each time you change the web.config.

An article explaining it more in detail is available here.

You can use the Configuration class which resides in system.configuration.

string configLocation = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
string configPath = Path.Combine(configLocation, "yourAppName");
Configuration configFile = ConfigurationManager.OpenExeConfiguration(configPath); configFile.AppSettings.Settings["TheSettingYouWantToChange"].Value = "NewValue"; configFile.Save(ConfigurationSaveMode.Modified);
