GetResponse（）在我的proxychecker c＃中抛出错误

Question

我正在尝试执行多线程代理检查，但GetResponse会抛出错误。我试图使用catch webException，仍然无法正常工作。我被困了请求帮助。你能告诉我我应该更改或添加到这段代码中吗？

    {
        string path = "C:\\users\\zsolt\\desktop\\proxies.txt";
        //string path = args[0];
        List<string> proxies = File.ReadLines(path).ToList();

        Parallel.ForEach(proxies, proxy =>
        {
             WebProxy myproxy = new WebProxy(proxy);
            WebRequest myWebRequest = WebRequest.Create("http://www.google.com");
            myWebRequest.Timeout = 3000;
            myWebRequest.Proxy = myproxy;
       //   WebResponse myWebResponse = myWebRequest.GetResponse();
       //   myWebResponse.Close();

            try
            {
                using (WebResponse response = myWebRequest.GetResponse())
                {

                    using (Stream data = response.GetResponseStream())
                    {
                        string text = new StreamReader(data).ReadToEnd();
                        Console.WriteLine(proxy, text);
                    }
                }
            }

            });

            Console.Read();
        }
    }
