C＃客户试图发送信息而不是听，为什么会发生这种情况？

Question

所以我正在编写 c# 客户端服务器程序，其中客户端从服务器接收信息，但是客户端似乎在成功连接后尝试发送信息而不是接收信息，

public void SL_Click(object sender, EventArgs e)
{
    try
    {
        TcpClient tcpclnt = new TcpClient();
        tcpclnt.Connect(RecieveIP.Text, 8001); // use the ipaddress as in the server program

        MessageBox.Show("Connected");
        
        String str = Console.ReadLine();
        Stream stm = tcpclnt.GetStream();
       
        ASCIIEncoding asen = new ASCIIEncoding();
        byte[] ba = asen.GetBytes(str);
        MessageBox.Show("Listening for information......");

        stm.Write(ba, 0, ba.Length);

        byte[] bb = new byte[100];
        int k = stm.Read(bb, 0, 100);

        for (int i = 0; i < k; i++)
            Console.Write(Convert.ToChar(bb[i]));
            
        string toattk = str.ToString();

我认为这是因为客户端和服务器确实成功连接，但是从服务器发送的消息从未被实际接收到。

服务器连接并将消息发送到另一台计算机时执行操作的代码：

private void Connectnattk_DoWork(object sender, DoWorkEventArgs e)
{
    try
    {
        IPAddress ipAd = IPAddress.Parse(ipv4.Text); //use local m/c IP address, and use the same in the client

        /* Initializes the Listener */
        TcpListener myList = new TcpListener(ipAd, 8001);

        /* Start Listeneting at the specified port */
        myList.Start();

        MessageBox.Show("The server is running at port 8001...");
        MessageBox.Show("The local End point is  :" + myList.LocalEndpoint);
        MessageBox.Show("Looking for other computer");

        Socket s = myList.AcceptSocket();
        Console.WriteLine("Found buddy " + s.RemoteEndPoint);

        ASCIIEncoding asen = new ASCIIEncoding();
        s.Send(asen.GetBytes(satt.Text));
        MessageBox.Show("The command " + satt.Text + " was sent to the computer with IP address " + ipv4.Text);

        byte[] b = new byte[100];
        int k = s.Receive(b);
        for (int i = 0; i < k; i++)
            Console.Write(Convert.ToChar(b[i]));

        /* clean up */

        s.Close();
        myList.Stop();
    }
    catch (Exception)
    {
        MessageBox.Show("Could not find other computer.");
    }

它们连接没有问题，但从服务器发送的消息永远不会出现在客户端上。我推测这是因为客户端试图发回响应而不是接收服务器发送的消息。还是有其他原因导致电脑连接后收不到消息？谢谢。
