我让客户机/服务器工作，客户机向服务器发送数据没有问题，现在我只有一个richtextbox，显示从客户机接收的数据。
我想做的是让服务器在richtextbox中显示接收到的数据，然后将消息发送到活动窗口（发生这种情况时，服务器将最小化到系统托盘）。
客户部分：

using System.Net;
using System.Net.Sockets;

private TcpClient client = new TcpClient();
    private IPEndPoint serverEndPoint = new IPEndPoint(IPAddress.Parse("MyIP"), 8888);


public Console()
{
    InitializeComponent();
    client.Connect(serverEndPoint);

}

private void SendMessage(string msg)
{
    NetworkStream clientStream = client.GetStream();

    ASCIIEncoding encoder = new ASCIIEncoding();
    byte[] buffer = encoder.GetBytes(msg);

    clientStream.Write(buffer, 0, buffer.Length);
    clientStream.Flush();

}

///...

private void button1_Click(object sender, EventArgs e)
{
    SendMessage("T");
}

using System.Net;
using System.Net.Sockets;
using System.Threading;

private TcpListener tcpListener;
private Thread listenThread;
private int connectedClients = 0;
private delegate void WriteMessageDelegate(string msg);

public Form1()
{
    InitializeComponent();
    Server();
}

private void Server()
{
    this.tcpListener = new TcpListener(IPAddress.Any, 8888);
    this.listenThread = new Thread(new ThreadStart(ListenForClients));
    this.listenThread.Start();
}

private void ListenForClients()
{
    this.tcpListener.Start();

    while (true)
    {
        TcpClient client = this.tcpListener.AcceptTcpClient();


        connectedClients++; 
        lblNumberOfConnections.Text = connectedClients.ToString();

        Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm));
        clientThread.Start(client);

    }
}

private void HandleClientComm(object client)
{
    TcpClient tcpClient = (TcpClient)client;
    NetworkStream clientStream = tcpClient.GetStream();

    byte[] message = new byte[4096];
    int bytesRead;

    while (true)
    {
        bytesRead = 0;

        try
        {
            bytesRead = clientStream.Read(message, 0, 4096);
        }
        catch
        {
            break;
        }

        if (bytesRead == 0)
        {
            connectedClients--;
            lblNumberOfConnections.Text = connectedClients.ToString();
            break;
        }

        ASCIIEncoding encoder = new ASCIIEncoding();


//Write message in RichTextBox and send keystrokes to active window

        string msg = encoder.GetString(message, 0, bytesRead);
        WriteMessage(msg);
     // SendKeys.Send(msg);

    }

    tcpClient.Close();
}

private void WriteMessage(string msg)
{
    if (this.rtbServer.InvokeRequired)
    {
        WriteMessageDelegate d = new WriteMessageDelegate(WriteMessage);
        this.rtbServer.Invoke(d, new object[] { msg });

    }
    else
    {
        this.rtbServer.AppendText(msg + Environment.NewLine);
    }

//Write message in RichTextBox

            string msg = encoder.GetString(message, 0, bytesRead);
            WriteMessage(msg);

        }

        tcpClient.Close();
    }

    private void WriteMessage(string msg)
    {
        if (this.rtbServer.InvokeRequired)
        {
            WriteMessageDelegate d = new WriteMessageDelegate(WriteMessage);
            this.rtbServer.Invoke(d, new object[] { msg });

        }
        else
        {
            this.rtbServer.AppendText(msg + Environment.NewLine);

// SEND KEYSTROKES TO ACTIVE WINDOW

            SendKeys.Send(msg);
        }

// SEND KEYSTROKES TO ACTIVE WINDOW
        if (msg.Equals("CTRL-T"))
            {
                SendKeys.Send("{^T}");
            }
            else if (msg.Equals("CTRL-H"))
            {
                SendKeys.Send("{^H}");
            }
            else
            {
                SendKeys.Send(msg);
            }

最佳答案

我想我会回答我自己的问题，因为我已经具备了我现在正在寻找的基本功能。
基本上，我想接受来自客户端应用程序的消息，并将其显示在服务器应用程序的文本框中，然后将该消息转换为活动窗口中的模拟按键。
在将按键发送到窗口之前，我必须确保只有一个数字的按键被立即发送到活动窗口，并且在发送之前捕获其他两个需要附加到它们的修饰符的已知命令，并对其进行修改，以便它们充当已修改的k按键，而不是作为文本块（即“ctrl-t”）发送，而不是实际的

//Write message in RichTextBox

        string msg = encoder.GetString(message, 0, bytesRead);
        WriteMessage(msg);

    }

    tcpClient.Close();
}

private void WriteMessage(string msg)
{
    if (this.rtbServer.InvokeRequired)
    {
        WriteMessageDelegate d = new WriteMessageDelegate(WriteMessage);
        this.rtbServer.Invoke(d, new object[] { msg });

    }
    else
    {
        this.rtbServer.AppendText(msg + Environment.NewLine);

// SEND KEYSTROKES TO ACTIVE WINDOW

if (msg.Equals("CTRL-T"))
        {
            SendKeys.Send("^T");
        }
        else if (msg.Equals("CTRL-H"))
        {
            SendKeys.Send("^H");
        }
        else
        {
            SendKeys.Send(msg);
        }
