Help with C# HttpWebRequest URI losing its encoding

Question

Having a problem with HttpWebRequest decoding my encoded URL.

var requestUrl = "https://www.google.com/webmasters/tools/feeds/http%3A%2F%2Fwww%2example%2Ecom%2F/crawlissues/";   
var request = (HttpWebRequest)WebRequest.Create(requestUrl);

When looking at end request URL is becomes:

https://www.google.com/webmasters/tools/feeds/http://www.example.com//crawlissues/

Which of course returns a 400 Bad request. I am guessing it is something todo with the URI class rather than HttpWebRequest. How do I stop this from happening?

Answer 1

Not sure but may be HttpServerUtility.UrlEncode method will help.

Upd. Alternatively you may use WebClient class.

Answer 2

Apparently the Uri decodes it in parts. I don't know who's right or wrong here, but see this duplicate question that describes a hack to bypass it:
