WPF基本的客户端和服务端通信代码

WPF 中的客户端和服务端通信可以使用多种方式实现，包括但不限于：

1. 使用 Socket 进行通信

客户端代码示例：

using System.Net.Sockets;

private void ConnectToServer(string serverIP, int serverPort)
{
    Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    clientSocket.Connect(serverIP, serverPort);

    // 发送数据
    byte[] data = Encoding.UTF8.GetBytes("Hello, server!");
    clientSocket.Send(data);

    // 接收数据
    byte[] buffer = new byte[1024];
    int count = clientSocket.Receive(buffer);
    string message = Encoding.UTF8.GetString(buffer, 0, count);
    MessageBox.Show(message);

    // 关闭连接
    clientSocket.Shutdown(SocketShutdown.Both);
    clientSocket.Close();
}

服务端代码示例：

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

private void StartServer(int port)
{
    Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    serverSocket.Bind(new IPEndPoint(IPAddress.Any, port));
    serverSocket.Listen(10);

    while (true)
    {
        Socket clientSocket = serverSocket.Accept();

        // 接收数据
        byte[] buffer = new byte[1024];
        int count = clientSocket.Receive(buffer);
        string message = Encoding.UTF8.GetString(buffer, 0, count);
        MessageBox.Show(message);

        // 发送数据
        byte[] data = Encoding.UTF8.GetBytes("Hello, client!");
        clientSocket.Send(data);

        // 关闭连接
        clientSocket.Shutdown(SocketShutdown.Both);
        clientSocket.Close();
    }
}

2. 使用 WCF 进行通信

客户端代码示例：

using System.ServiceModel;

private void ConnectToServer(string serverIP, int serverPort)
{
    EndpointAddress endpoint = new EndpointAddress($"net.tcp://{serverIP}:{serverPort}/MyService");
    NetTcpBinding binding = new NetTcpBinding();

    using (MyServiceClient client = new MyServiceClient(binding, endpoint))
    {
        // 调用服务端方法
        string message = client.SayHello("Hello, server!");
        MessageBox.Show(message);
    }
}

服务端代码示例：

using System.ServiceModel;

[ServiceContract]
public interface IMyService
{
    [OperationContract]
    string SayHello(string message);
}

public class MyService : IMyService
{
    public string SayHello(string message)
    {
        MessageBox.Show(message);

        return "Hello, client!";
    }
}

private void StartServer(int port)
{
    ServiceHost host = new ServiceHost(typeof(MyService));
    host.AddServiceEndpoint(typeof(IMyService), new NetTcpBinding(), $"net.tcp://localhost:{port}/MyService");
    host.Open();
}

以上示例仅供参考，具体实现方式需要根据实际需求进行调整。
