(unity)客户端与服务器创建的简单例子C#编写

客户端：

using System.Collections;
using System.Collections.Generic;
using System.Net;
using System.Net.Sockets;
using UnityEngine;
using UnityEngine.UI;
public class Client : MonoBehaviour
{
    public InputField send_text;//用来获取用户界面输入的信息
    public Text show;//显示是否连接
   
    public Text showing_text;//显示已经发送的消息
    Socket socket;
    // Start is called before the first frame update
    void Start()
    {
        
        
    }

    // Update is called once per frame
    void Update()
    {
        if(socket == null)
        {
            show.text = "未连接";
        }
        else
        {
            show.text = "已连接";
        }
    }
    public void Connected()
    {
        try
        {
            socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //IPAddress iPAddress = Dns.GetHostEntry(127.0.0.1)
            socket.Connect("127.0.0.1", 8888);//连接的服务器地址和端口

        }
        catch(SocketException ex)
        {
            socket = null;
            Debug.Log("连接失败" + ex.ToString());
        }
    }

    public void Send()
    {
        //byte[] bytes = new byte[1024];//创建容器用来储存服务器传来的消息
        string send_mas = send_text.text;
        byte[] bytes = System.Text.Encoding.UTF8.GetBytes(send_mas);
        socket.Send(bytes);

        int count = send_text.text.Length;

        string showing = System.Text.Encoding.UTF8.GetString(bytes);

        showing_text.text = showing;

		
    }
    public void Break()
    {
        socket.Close();//关闭客户端
    }
}

在unity中创建对应的组件，分别为不同的按钮选择监听事件

服务器：

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

namespace Severmyself
{
    
    class Program
    {
        static Socket socket;
        static void Main(string[] args)
        {
            try
            {
                socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//定义运转环境，传输方式，传输协议

                IPAddress iP = IPAddress.Parse("127.0.0.1");

                IPEndPoint endPoint = new IPEndPoint(iP, 8888);//定义网络终端

                socket.Bind(endPoint);

                socket.Listen(100);//定义最大连接数并且将程序由主动连接变为被动连接

                Console.WriteLine("服务器启动成功！");

               
                Socket socket1 =  socket.Accept();
                byte[] bytes = new byte[1024];//定义储存客户端发来的数据

                int count = socket1.Receive(bytes);
                
                
                    count = socket1.Receive(bytes);

                    string Receive_mas = System.Text.Encoding.UTF8.GetString(bytes, 0, count);

                    Console.WriteLine("客户端：" + Receive_mas);
                    
                   Console.ReadLine();
                
                socket1.Close();
        
               

            }
            catch (SocketException ex)
            {
                Console.WriteLine("Connect was failed" + ex.ToString());
            }
            
        }
    }
}

由于实现的是单个客户端与服务器的连接，所以这里面的监听只调用了一次，也就是说，仅能处理一个客户端的请求。
