自己觉得比较有用的WindowsPhone7 Http异步请求的一段简单代码

WebClient webClient = new WebClient();    webClient.DownloadStringAsync(new Uri("urlstring"));  webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient_DownloadStringCompleted);//webClient_DownLoadStringCompleted Event        void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)        {            string result = e.Result;            System.Diagnostics.Debug.WriteLine(result);            MessageBox.Show(result);        }
