如何在WinForms中重启Timer？

Question

我在c＃中遇到计时器控制问题。请参阅代码中的解释，

Onform_Load
{ 
 // On form load initiating the timer control, to verify whether the server       connection is established or not
 timer2 = new Timer();
 timer2.Interval = 1000;
 timer2.Tick += new EventHandler(timer2_Tick);
 timer2.Start();
}

private void timer2_Tick(object sender, EventArgs e)
{     
   Socket sock = Sockets.CreateTCPSocket(IPAddress, Convert.ToInt32(Port));
   client = new ClientInfo(sock, false); // Don't start receiving yet
   client.OnReadBytes += new ConnectionReadBytes(ReadData);
   client.OnClose += new ConnectionClosed(OnClose);
   try
   {
       client.BeginReceive();
       OnConnected();
   }
   catch
   {
       OnClose();             
   }
}
void OnConnected()
{
  //connection established message
}
void OnClose(ClientInfo clnt)
{ 
  //Connection Closed
}                    

通过使用上述 timer2_Tick 事件，无论是否建立连接，应用程序都会不断访问服务器。

  

在建立连接时 停止计时器 。

和

  

启动计时器连接关闭时。

见下面的代码：

void OnConnected()
{
    timer2.Stop();
  //connection established message
}
void OnClose(ClientInfo clnt)
{ 
    timer2.Start();// here i tried timer2.Enabled and intiated the interval. but it is not working
  //Connection Closed
}  

任何人都可以帮助我，如何在基于条件的情况下启动和停止计时器，

提前致谢。
