The statuscode in webexception is not reliable.

Use the followingCode25 thousand domain names were identified and a small part of the results were incorrect.

// Lots of other interesting code up here... catch (webexception Wex) {// typical HTTP Error if (Wex. status = webexceptionstatus. protocolerror) {httpwebresponse wrsp = (httpwebresponse) wex. response; throw new httpexception (INT) wrsp. statuscode, wrsp. statusdescription);} else {Throw new httpexception (500, Wex. message) ;}} // other interesting code goes down here...

 

Google is a component and the test is accurate. It seems to be charged. Http://www.example-code.com/csharp/http_getStatus.asp
