获得了这些代码

这是c＃中的一个简单代理服务器。用我的Android手机我连接到它:(代理主机名：192.1.1.24（我的电脑的IP）代理端口：7777）。但是服务器没有得到任何请求。有谁知道为什么这不起作用以及为什么我的手机无法连接到代理？顺便说一句，这两个设备在一个网络中，我知道防火墙不会阻止请求。

这是代码：

using System;
using System.IO;
using System.Linq;
using System.Net;
using System.Threading;

namespace SimpleHttpProxy
{
public class Program
{
    private static void Main(string[] args)
    {
        var listener = new HttpListener();
        listener.Prefixes.Add("http://*:7777/");
        listener.Start();
        Console.WriteLine("Listening...");
        while (true)
        {
            var ctx = listener.GetContext();
            new Thread(new Relay(ctx).ProcessRequest).Start();
        }
    }
}

public class Relay
{
    private readonly HttpListenerContext originalContext;

    public Relay(HttpListenerContext originalContext)
    {
        this.originalContext = originalContext;
    }

    public void ProcessRequest()
    {
        string rawUrl = originalContext.Request.RawUrl;
        ConsoleUtilities.WriteRequest("Proxy receive a request for: " + rawUrl);

        var relayRequest = (HttpWebRequest) WebRequest.Create(rawUrl);
        relayRequest.KeepAlive = false;
        relayRequest.Proxy.Credentials = CredentialCache.DefaultCredentials;
        relayRequest.UserAgent = this.originalContext.Request.UserAgent;

        var requestData = new RequestState(relayRequest, originalContext);
        relayRequest.BeginGetResponse(ResponseCallBack, requestData);
    }

    private static void ResponseCallBack(IAsyncResult asynchronousResult)
    {
        var requestData = (RequestState) asynchronousResult.AsyncState;
        ConsoleUtilities.WriteResponse("Proxy receive a response from " + requestData.context.Request.RawUrl);

        using (var responseFromWebSiteBeingRelayed = (HttpWebResponse) requestData.webRequest.EndGetResponse(asynchronousResult))
        {
            using (var responseStreamFromWebSiteBeingRelayed = responseFromWebSiteBeingRelayed.GetResponseStream())
            {
                var originalResponse = requestData.context.Response;

                if (responseFromWebSiteBeingRelayed.ContentType.Contains("text/html"))
                {
                    var reader = new StreamReader(responseStreamFromWebSiteBeingRelayed);
                    string html = reader.ReadToEnd();
                    //Here can modify html
                    byte[] byteArray = System.Text.Encoding.Default.GetBytes(html);
                    var stream = new MemoryStream(byteArray);
                    stream.CopyTo(originalResponse.OutputStream);
                }
                else
                {
                    responseStreamFromWebSiteBeingRelayed.CopyTo(originalResponse.OutputStream);
                }
                originalResponse.OutputStream.Close();
            }
        }
    }
}

public static class ConsoleUtilities
{
    public static void WriteRequest(string info)
    {
        Console.BackgroundColor = ConsoleColor.Blue;
        Console.ForegroundColor = ConsoleColor.White;
        Console.WriteLine(info);
        Console.ResetColor();
    }
    public static void WriteResponse(string info)
    {
        Console.BackgroundColor = ConsoleColor.DarkBlue;
        Console.ForegroundColor = ConsoleColor.Yellow;
        Console.WriteLine(info);
        Console.ResetColor();
    }
}

public class RequestState
{
    public readonly HttpWebRequest webRequest;
    public readonly HttpListenerContext context;

    public RequestState(HttpWebRequest request, HttpListenerContext context)
    {
        webRequest = request;
        this.context = context;
    }
}

  }
