Instead of using the Configuration class, open the file as a regular Xml file and make your changes. Note that when you are doing this, when you save the file back, any Comments in your .config file will be removed by the Xml class. To prevent this, you must read ALL types of Xml nodes from the original configuration file and write them all back.
