各位大神好:

想請問讀卡機透過tcpip模組連線，想寫程式讀1621port(soyal)傳來的資料，因為目前只有一台，但是以後想說有多台，先用其他電腦主機模擬..使用非同步與多執行緒處理，但如果用電腦主機(有個連線程式跟ConsoleClient連線)模擬讀卡機，大概過5小時或過1天，連線就與主程式中斷連線，想請問要怎麼有機制自動重新連線呢?
以下ip:166.187是用電腦模擬卡機跟主程式連線 ip:192.168.20.15是讀卡機跟主程式連線
謝謝

主程式ConsoleClient

public void ConnectToserver()
{
   int numberOfClients = 0;
   //預設主機IP
   string[] arrayIP = new string[] {"192.168.20.15", "192.168.20.16", "192.168.20.187" };  
   //先建立IPAddress物件,IP為欲連線主機之IP
   for (int i = 0; i < arrayIP.Length; i++)
   {
     string hostIP = arrayIP[i];
     IPAddress ipa = IPAddress.Parse(hostIP);
     //建立IPEndPoint
     IPEndPoint ipe = new IPEndPoint(ipa, 1621);
     //先建立一個TCPClient
     TcpClient tcpClient = new TcpClient();
       try
       {
         Console.WriteLine("讀卡機主機IP" + ipa.ToString());
         Console.WriteLine("連線至讀卡機主機中...\n");
           if (!tcpClient.ConnectAsync(ipa, 1621).Wait(1000)) //5s
                {
                   Console.WriteLine(ipa+ "連線失敗!");
                }
           if (tcpClient.Connected)
                {        
                  MultipleClient mutipleclient = new MultipleClient(tcpClient,ipa.ToString());
                  Thread myThread = new Thread(new ThreadStart(mutipleclient.Communicate));
                   numberOfClients += 1;
                   myThread.IsBackground = true;
                   myThread.Start();
                   myThread.Name = tcpClient.Client.RemoteEndPoint.ToString();                       
                 }

              else
               {
                  Console.WriteLine("連線失敗!");
               }
        }

       catch (Exception ex)
        {
              tcpClient.Close();
              Console.WriteLine(ex.Message);
         }

      } //for loop
            Console.Read();
}

MultipleClient 類別

private TcpClient mTcpClient;
        private String ip;
        public MultipleClient(TcpClient _tcpClient,String ip) /
        {
            this.mTcpClient = _tcpClient;
            this.ip = ip;
        }

        public void Communicate()
        {
            try
            {
                Console.WriteLine("連線成功aa"+this.ip.ToString());
                CommunicationBasic cb = new CommunicationBasic();
                Byte[] sendmessage = new byte[] { 0x7e, 0x04, 0x01, 0x25, 0xdb, 0x01 }; //送指令過去 看能不能讀卡
               // while (true)
                //{
                    cb.SendMsg(sendmessage, this.mTcpClient);
                    Console.WriteLine("TX:" + staticClass.ToHexString(sendmessage, sendmessage.Length)); //靜態類別不用new
                string[] array = cb.ReceiveMsg(this.mTcpClient);
                    Console.WriteLine("RX:" +array[0]); //卡機回覆的資訊,如果沒回覆會卡住
                    Console.WriteLine("字串長度:"+array[1]);
                //}
            }
            catch
            {
                Console.WriteLine("伺服器端強制關閉連線!" + this.ip.ToString());
                this.mTcpClient.Close();
            }
        }
