Editing Web.config programmatically

Question

What is a good way to edit a Web.config file programmatically?

I looked into System.Xml but couldn\'t find any obvious answers.

Answer 1

Yes I agree with Josh. I have tried this before and I've had two negative effects:

1. Slow loading if the current page after postback because ASP.NET is loading the web.config and all related resources
2. If you change the web.config early enough in the load cycle (e.g. global.asax events) the site may never load or fail in unpredictable ways
