本文介绍了一种通过设置WebProxy属性来访问特定WebService的方法。详细展示了如何创建WebProxy实例，设置代理服务器的IP和端口，以及如何绕过本地请求的代理。同时，演示了如何使用HttpWebRequest发起GET请求，并正确设置请求头和代理信息。

try
            {
                const int port = 8***;//代理机器端口
                const string IP = "10.**.**.**"; //代理机器IP
                WebProxy _WP = new WebProxy(IP, port);
                _WP.BypassProxyOnLocal = true;
                ICredentials credentials = new NetworkCredential();
                _WP.Credentials = credentials;
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://192.****");//代理机器调用的webService地址
                request.Method = "GET";
                request.ContentType = "text/html;charset=UTF-8";
                request.Proxy = _WP;
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                Stream myResponseStream = response.GetResponseStream();
                StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
                string retString = myStreamReader.ReadToEnd();
                ClientScript.RegisterClientScriptBlock(Page.GetType(), "", "alert('" + retString + "');", true);
                myStreamReader.Close();
                myResponseStream.Close();
            }
            catch(Exception ex)
            {
                ClientScript.RegisterClientScriptBlock(Page.GetType(), "", "alert('" + ex.Message + "');", true);
            }
