TcpClient 案例二

# Tcp服务端：

```java
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

class TcpServerExample
{
    public static void Main()
    {
        TcpListener listener = new TcpListener(“127.0.0.1", 8000);
        listener.Start();
        Console.WriteLine("Server is listening on port 8000...");

TcpClient client = listener.AcceptTcpClient();
        NetworkStream stream = client.GetStream();

byte[] data = new byte[1024];
        int bytesRead = stream.Read(data, 0, data.Length);
        Console.WriteLine("Received: " + Encoding.ASCII.GetString(data, 0, bytesRead));

byte[] response = Encoding.ASCII.GetBytes("Hello, Client!");
        stream.Write(response, 0, response.Length);

stream.Close();
        client.Close();
        listener.Stop();
    }
}
```

# TCP客户端：

class TcpClientExample
{
    public static void Main()
    {
        TcpClient client = new TcpClient("127.0.0.1", 8000);
        NetworkStream stream = client.GetStream();

byte[] message = Encoding.ASCII.GetBytes("Hello, Server!");
        stream.Write(message, 0, message.Length);

byte[] data = new byte[1024];
        int bytesRead = stream.Read(data, 0, data.Length);
        Debug.WriteLine("Received: " + Encoding.ASCII.GetString(data, 0, bytesRead));

stream.Close();
        client.Close();
    }
}
