Question

我有一个很大的列表，包含代理服务器及其相应的端口。如果它们正在工作，我该如何检查？

Answer 1

工作？好吧，你必须使用它们来查看它们是否正常工作。

如果你想看看他们是否在线，我猜ping是第一步。

using System.Net.NetworkInformation;

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

    try
    {
        PingReply reply = ping.Send(address, 2000);
        if (reply == null) return false;

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

我喜欢通过代理进行WhatIsMyIP检查作为测试。

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();
      Console.WriteLine("Success:" + success.ToString() + "|Connection Time:" + sw.Elapsed.TotalSeconds + "|ErrorMsg" + errorMsg);
    }
  });
}

但是，我可能建议明确测试不同类型（即http，https，socks4，socks5）。以上仅检查https。在为https://theproxisright.com/#proxyChecker构建ProxyChecker时，我开始使用上面的代码，然后最终必须扩展其他功能/类型。

试试这个：

public static bool SoketConnect(string host, int port)
{
    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);
        if (connsock.Connected)
        {
            is_success = true;
        }
        connsock.Close();
    }
    catch (Exception)
    {
        is_success = false;
    }
    return is_success;
}

string strIP = "10.0.0.0";
int intPort = 12345;

  public static bool PingHost(string strIP , int intPort )
    {
        bool blProxy= false;
        try
        {
            TcpClient client = new TcpClient(strIP ,intPort );

            blProxy = true;
        }
        catch (Exception ex)
        {
            MessageBox.Show("Error pinging host:'" + strIP + ":" + intPort .ToString() + "'");
            return false;
        }
        return blProxy;
    }

    public void Proxy()
    {
        bool tt = PingHost(strIP ,intPort );
        if(tt == true)
        {
            MessageBox.Show("tt True");
        }
        else
        {
            MessageBox.Show("tt False");
        }
