使用套接字的 C# 线程

Question

这是套接字的另一个问题。

我正在用 C# 为游戏制作机器人，到目前为止，我可以让它们进行连接以及类似的操作，但它只是在同一个套接字上同时连接多个帐户。我想我可以通过线程化包含 socket.connect() 函数的函数然后将数据包发送到服务器来做到这一点。我什至查看了过去的 python 脚本，它基本上在做同样的事情。

以下是 Python 代码示例：

if bots["loaded"] < b0ts:

                    bots["accounts"][acc[0]] = acc[1].replace("\n", "")

                    bot_thread = threading.Thread(target=self.verify_bot, args=(acc[0],))

                    bot_thread.start()

基本上我打算尝试将其转换为 C#，认为它会起作用。但另一方面，几乎所有的函数在几乎每种编程语言中都可能不同。

这是我在 C# 中用于线程部分的代码，出于某种原因我使用了后台工作程序，但我也不认为这是它无法正常工作的原因，所以为什么不呢。

Thread t;                                                             
    private void backgroundWorker2_DoWork(object sender, DoWorkEventArgs e)
    {
        for(int i = 0; i <= acc.Items.Count - 1; i++)
        {
            if(backgroundWorker2.CancellationPending == true)
            {
                e.Cancel = true;
                break;
            }
            else
            {
                t = new Thread(() => verify_bots(acc.Items[i].ToString().Split(':')[0], acc.Items[i].ToString().Split(':')[1]));
                t.Start();
            }
        }
    }

顺便说一句，拆分是为了用户名和密码，以防万一有人对此感到困惑。无论如何，只有 1 个机器人仍然连接，然后我从套接字收到错误，因为它之前已经通过一个连接或类似的东西连接，或者我认为的其他东西。

这就是我的问题所在，因为它在 python 中运行良好，而且通常我尝试转换为 C# 的东西都有效。这是 verify_bots 函数，以便人们更容易弄清楚。

private void verify_bots(string username, string password)
    {
        CheckForIllegalCrossThreadCalls = false;

        string login_data = string.Format("userID={0}&password={1}", username, password);
        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] data = encoding.GetBytes(login_data);

        HttpWebRequest request;

        request = (HttpWebRequest)WebRequest.Create("https://www.binweevils.com/login");

        getTick(request); // getting cookies

        request.Method = "POST";
        request.KeepAlive = true;
        request.UserAgent = "1337JjsHd";
        request.CookieContainer = logincookie;
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = data.Length;

        Stream stream;

        stream = request.GetRequestStream();
        stream.Write(data, 0, data.Length);
        stream.Close();

        HttpWebResponse response;

        response = request.GetResponse() as HttpWebResponse;

        StreamReader responsereader;

        responsereader = new StreamReader(response.GetResponseStream());

        string final = responsereader.ReadToEnd();

        if(final.Contains("register.php"))
        {
            console.Text = console.Text + username+" Failed!\n";
        }
        else
        {
            string post = "";
            ASCIIEncoding encoding1 = new ASCIIEncoding();
            byte[] data1 = encoding1.GetBytes(post);

            request = (HttpWebRequest)WebRequest.Create("https://lb.binweevils.com/php2/weevil/get-login-details.php");
            request.Method = "POST";
            request.KeepAlive = true;
            request.UserAgent = "1337JjsHd";
            request.CookieContainer = logincookie;
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data1.Length;

            stream = request.GetRequestStream();
            stream.Write(data1, 0, data1.Length);
            stream.Close();

            response = request.GetResponse() as HttpWebResponse;

            responsereader = new StreamReader(response.GetResponseStream());

            final = responsereader.ReadToEnd();

            try
            {
                string[] a = new string[] { "loginKey=" };
                var aa = final.Split(a, StringSplitOptions.None);

            {
                console.Text = console.Text + "Failed to get loginkey.\n";
            }

            sock.Connect(ip, port);

            byte[] recv = new byte[2048];

            sendRawPackets(sock, "<policy-file-request/>");
            sock.Receive(recv);

Answer 1

线程启动需要相当长的时间，所以当你的for 循环完成和i == acc.Items.Count - 1 时。这意味着每个线程都在使用acc.Items[acc.Items.Count - 1]，因此“在同一个套接字上同时连接多个帐户”。

简单的解决方法是这样的：

    for(int i = 0; i <= acc.Items.Count - 1; i++)
    {
        if(backgroundWorker2.CancellationPending == true)
        {
            e.Cancel = true;
            break;
        }
        else
        {
            int a_copy_of_i = i;
            t = new Thread(() => verify_bots(acc.Items[a_copy_of_i].ToString().Split(':')[0], acc.Items[a_copy_of_i].ToString().Split(':')[1]));
            t.Start();
        }
    }

已经想通了。好像每次我被一个项目困住的时候，我迟早会自己弄清楚:))))

还是谢谢。
