Invoke在C#中實現遠程控制的案例

在C#中，你可以使用System.Runtime.Remoting或更現代的System.Net.Sockets和System.Threading來實現遠程控制。這里我將給出一個簡單的基于TCP套接字的遠程控制示例。

服務器端

首先，我們創建一個簡單的服務器，它將監聽來自客戶端的連接，并執行一些操作（在這個例子中，我們只是返回一個字符串）。

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

class Server
{
    static void Main()
    {
        TcpListener server = null;
        try
        {
            Int32 port = 13000;
            IPAddress localAddr = IPAddress.Parse("127.0.0.1");

            server = new TcpListener(localAddr, port);

            server.Start();
            Console.WriteLine("Server started...");

            while (true)
            {
                TcpClient client = server.AcceptTcpClient();
                Console.WriteLine("Client connected!");

                NetworkStream stream = client.GetStream();
                byte[] data = new byte[256];
                int i = stream.Read(data, 0, data.Length);

                string received = Encoding.ASCII.GetString(data, 0, i);
                Console.WriteLine("Received: {0}", received);

                string response = "Hello from server!";
                data = Encoding.ASCII.GetBytes(response);
                stream.Write(data, 0, data.Length);

                client.Close();
                Console.WriteLine("Client disconnected!");
            }
        }
        catch (SocketException e)
        {
            Console.WriteLine("SocketException: {0}", e);
        }
        finally
        {
            if (server != null)
            {
                server.Stop();
            }
        }
    }
}

客戶端

接下來，我們創建一個簡單的客戶端，它將連接到服務器并發送一些數據。

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

class Client
{
    static void Main()
    {
        TcpClient client = null;
        try
        {
            Int32 port = 13000;
            IPAddress serverAddr = IPAddress.Parse("127.0.0.1");

            client = new TcpClient(serverAddr, port);
            Console.WriteLine("Connected to server!");

            NetworkStream stream = client.GetStream();
            string message = "Hello from client!";
            byte[] data = Encoding.ASCII.GetBytes(message);
            stream.Write(data, 0, data.Length);

            byte[] response = new byte[256];
            int i = stream.Read(response, 0, response.Length);
            string received = Encoding.ASCII.GetString(response, 0, i);
            Console.WriteLine("Received: {0}", received);
        }
        catch (SocketException e)
        {
            Console.WriteLine("SocketException: {0}", e);
        }
        finally
        {
            if (client != null)
            {
                client.Close();
            }
        }
    }
}

這個示例展示了如何使用TCP套接字在C#中實現簡單的遠程控制。你可以根據需要擴展這個示例，例如添加身份驗證、加密、多線程等。

請注意，這只是一個基本的示例，用于說明如何使用C#實現遠程控制。在實際應用中，你可能需要考慮更多的安全性和穩定性問題。
