Edit an external mapped configuration file

Question

I just found out that i can read an external XML file like a configuration file if it is in the right format.

ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
configMap.ExeConfigFilename = @"******\TextFile1.txt";
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);
string fileName = config.AppSettings.Settings["FileName"].Value;
string className = config.AppSettings.Settings["ClassName"].Value;
string methodName = config.AppSettings.Settings["MethodName"].Value;

I was wondering of it is possible to edit that Configuration file in some way, please let me know if ti is possible.
