Windows forms text box should accept only url name

Question

Hi I need to validate that a textbox should accept only url names. Can anybody tell me please. I would be really thankful.

I don´t think there is a built in method or class that you can use to validate a string as a legal url. But you can use regex, something like ["^a-zA-Z0-9-._"]+.([a-zA-Z][a-zA-Z]) If you use the code from Ranhiru you will not get it right with for instance bild.de and s.int which are both valid urls.
