Question

我想在使用它们之前检查列表中的代理是否正常工作，是否可能？

对于HTTP / HTTPS来说很容易，因为你只需要使用webclient而不是袜子？

我认为这可以适用于所有人

public static bool SoketConnect(string addresse)
    {
        string[] proxy = addresse.Split(':');
        if (proxy.Count() == 2)
        {
            string host = proxy[0];
            int port = Convert.ToInt32(proxy[1]);

            var is_success = false;
            try
            {
                var connsock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                connsock.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 200);
                System.Threading.Thread.Sleep(500);
                var hip = IPAddress.Parse(host);
                var ipep = new IPEndPoint(hip, port);
                connsock.Connect(ipep);
                    try
                    {
                        byte[] outStream = System.Text.Encoding.ASCII.GetBytes("ping");
                        byte[] inStream = new byte[100];
                        connsock.Send(outStream);
                        connsock.ReceiveTimeout = 500;
                        connsock.Receive(inStream);
                        string message = System.Text.Encoding.ASCII.GetString(inStream);
                        foreach (var bytes in inStream)
                        {
                            if (bytes != 0)
                            {
                                is_success = true;
                                break;
                            }
                        }
                        connsock.Disconnect(false);
                    }
                    catch(Exception ex)
                    {
                        is_success = false;
                    }
                connsock.Close();
            }
            catch (Exception ex)
            {
                is_success = false;
            }
            return is_success;
        }
        else
            return false;
    }

但我总是得到例外

＆＃34;底层连接已关闭：连接已关闭出乎意料＆＃34。 System.Net.WebException

编辑：仍然没有帮助，需要一个答案 EDIT2：只有ping代理才是正确的事情

Answer 1

据我所知，您必须使用它们来查看它们是否正常工作。我建议以下其中一项：

ping - here班级：

using System.Net.NetworkInformation;

private static bool CanPing(string address)
{
    Ping myping = new Ping();

    try
    {
        PingReply reply = myping.Send(address, 2000);

        if (reply == null) 
            return false;

        return (reply.Status == IPStatus.Success);
    }
    catch (PingException e)
    {
        return false;
    }
}

做一个＆＃34;什么是我的IP？＆＃34;通过代理：

public static void TestProxies() 
{
    var lowp = new List<WebProxy> { new WebProxy("1.2.3.4", 8080), new WebProxy("5.6.7.8", 80) };

    Parallel.ForEach(lowp, wp => {

        var success = false;
        var errorMsg = "";
        var sw = new Stopwatch();

        try 
        {
              sw.Start();
              var response = new RestClient 
              {
                BaseUrl = "https://webapi.theproxisright.com/",
                Proxy = wp
              }.Execute(new RestRequest { Resource = "api/ip", Method = Method.GET, Timeout = 10000, RequestFormat = DataFormat.Json });

              if (response.ErrorException != null) 
                 throw response.ErrorException;

              success = (response.Content == wp.Address.Host);
        } 
        catch (Exception ex) 
        {
            errorMsg = ex.Message;
        } 
        finally 
        {
            sw.Stop();
        }
      });
}
