简单的unity 客户端与服务端互相发送消息

服务器部分用C#写的

首先是 游戏client

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;
using System.Collections;

namespace wsocketbydx
{
    class GameClient
    {
        public static Hashtable allClient = new Hashtable();   
        public static List<string> ipList = new List<string>();
        private TcpClient _client;
        public string _clientIP;
        public string _clientNick;
        private byte[] data;
        
        public GameClient(TcpClient client)
        {
            this._client = client;
            this._clientIP = client.Client.RemoteEndPoint.ToString();
            if (allClient.Count <= 2)
            {
                allClient.Add(this._clientIP, this);
                ipList.Add(this._clientIP);
                data = new byte[this._client.ReceiveBufferSize];
                client.GetStream().BeginRead(data, 0, System.Convert.ToInt32(this._client.ReceiveBufferSize), RceiveMessage, null);
                this.sendMessage("login success");
            }
            else
            {
                this.sendMessage("connect num is max,so connect failed");
            }
        }
        public void RceiveMessage(IAsyncResult ar)
        {
            int bytesread;
            try
            {
                lock (this._client.GetStream())
                {
                    bytesread = this._client.GetStream().EndRead(ar);
