Writing a new KEY-VALUE pair into configuration file

[Guest]

Hi,
i have to write a new KEY VALUE pair programatically into the app.config file.

is this possible? i tried the ConfigurationSettings.AppSettings but it
raises an exception saying that Collection is Read Only.

so the question is ... upon clicking a button i want to add a new KEY VALUE
pair to the Config File.. how do i do this?

thanks

Well, there seems to be a reason that it is readonly. And here is one
article on why it is a bad idea to write to app.config:

But, if you really, really think you need to write to this file, you can
always load it into an XmlDocument object and add what you need that
way.
