Question

我使用以下代码从实时服务器获取数据......

try
            {
    var httpReq = (HttpWebRequest)HttpWebRequest.Create(new Uri(url_builder.ToString()));
                httpReq.BeginGetResponse((ar) =>
                {
                        var request = (HttpWebRequest)ar.AsyncState;

                        using (var response = (HttpWebResponse)request.EndGetResponse(ar))
                        {

                            //Enter Code here............................

                            response.Close();
                        }
                });
                }, httpReq);
 }
            catch (Exception ex)
            {
                Global.EmailExceptionMessage(ex);
            }

获得内部异常，即

内部异常：在System.Net.WebConnection.HandleError（WebExceptionStatus st，System.Exception e，System.String where）在System.Net.WebConnection.ReadDone（IAsyncResult结果）

您可以尝试使用这一个代码来获取httpresponse。

HttpWebRequest request = WebRequest.Create("http://google.com") as HttpWebRequest;

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        WebHeaderCollection header = response.Headers;
        var encoding = ASCIIEncoding.ASCII;
        using (var reader = new System.IO.StreamReader(response.GetResponseStream(), encoding))
        {
            string responseText = reader.ReadToEnd();
        }

获取响应流时出错（ReadDone2）：ReceiveFailure
