请看代码：

    public sealed string GetGscCurrentUser()
    {
        HttpWebRequest webRequest = null;
        StreamReader responseReader = null;
        try
        {
            //ashx Url
            string getGscUserUrl = "http:/xxx.com/GscHandler.ashx";
            //加入参数，用于更新请求
            string urlHandler = getGscUserUrl + "?id=" + Guid.NewGuid();
            webRequest = (HttpWebRequest)HttpWebRequest.Create(urlHandler);
            webRequest.Timeout = 3000;//3秒超时
            //调用ashx，并取值
            responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
            string currentUserGulid = responseReader.ReadToEnd();
            return currentUserGulid.Trim();
        }
        catch
        {
            return "";
        }
        finally
        {
            responseReader.Close();
            responseReader.Dispose();
        }
    }

需要授权时写法如下：

        public string GetGscCurrentUser()
        {
            HttpWebRequest webRequest = null;
            StreamReader responseReader = null;
            try
            {
                string getGscUserUrl = System.Configuration.ConfigurationManager.AppSettings["GscGetUserUrl"];
                string urlHandler = getGscUserUrl + "?id=" + Guid.NewGuid();
                webRequest = (HttpWebRequest)HttpWebRequest.Create(urlHandler);
                webRequest.Timeout = 3000;//3秒超时
                webRequest.PreAuthenticate = true;
                NetworkCredential gscCred = new NetworkCredential("account", "***");
                webRequest.Credentials = gscCred;
                responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
                string currentUserGulid = responseReader.ReadToEnd();
                return currentUserGulid.Trim();
            }
            catch
            {
                return "";
            }
            finally
            {
                responseReader.Close();
                responseReader.Dispose();
            }
        }
