我在第3行的GetResponseCallback（IAsyncResult asynchronousResult）中收到错误ie response =（HttpWebResponse）webRequest.EndGetResponse（asynchronousResult）;
如何解决这个问题请让我知道。没有得到如何摆脱这个问题

}
iam getting the error in GetResponseCallback(IAsyncResult asynchronousResult) at line 3 ie response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
how to solve this problem please let me know.iam not getting how to came out of this problem
