.NET Forum / .NET Framework / New Users / January 2006Writing to the APP.CONFIG file
How would I write or update a key in a section of the APP.CONFIG or my application's.EXE.CONFIG file? Treat like an XML document. Remember that you'll need to have modify rights on the file.

This is only possible in .Net Framework 2.0. You can use the ConfigurationElement.SerializeElement() method. The IsReadOnly Property will inform you if the ConfigurationElement can be modified.

As Christopher pointed out, you will need permissions on the config.file. The new System.Configuration namespace contains new classes for working with configuration files (using the ConfigurationManager). It is best documented in the "Protected Configuration" topics for ASP.NET apps, but can also be applied to Windows apps. See also "Storing and Retrieving Connection Strings" http://msdn2.microsoft.com/en-us/library/ms254494.aspx for some sample code demonstrating reading and writing to the connectionStrings section. --Mary >How would I write or update a key in a section of the APP.CONFIG or my >application's.EXE.CONFIG file?
