https://accounts.google.com/o/oauth2/token?code=[code]&grant_type=authorization_code&client_id=[clientId]&client_secret=[clientSecret]&redirect_uri=http://localhost:52731/Common/Index this is the url that i m sending in webrequest.create(url); is there any thing i m missing?

well if for example code will be "abcd+efg" you need to url-encode it. Because + means space in url wich is something you dont want. But I don't know if that is your case :). Might be something completly different, but it was first thing on my mind to check.

When I'm running your post I receive an 411 error - POST requests require a Content-length header

Something is definitely fishy.
