winform 多个计时器操作问题

Question

目的：通过modbus TCP/IP 协议访问服务器端过程：现在有2个计时器，分别传不同的指令，向服务器请求，如下代码：
 
请求     
        private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            c.send("09 20 00 0A", "03");//发送请求指令
            ReciveData1();        private void timer2_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            c.send("09 34 00 0A", "03");//发送请求指令          
            ReciveData2();
         }接收：
        //从线程池接受响应数据(读T1-T10：Actual)
        private void ReciveData1()
        {
            ThreadPool.QueueUserWorkItem(new WaitCallback(LongTask1));
        }
        //从线程池接受响应数据(读T1-T10：Setpoint)
        private void ReciveData2()
        {
            ThreadPool.QueueUserWorkItem(new WaitCallback(LongTask2));
        }
       public void LongTask1(object obj)
       {
            string[] strReceive = new string[10];            strReceive = c.receive();            this.label65.Text = strReceive[0];
            this.label64.Text = strReceive[1];
            this.label63.Text = strReceive[2];
            this.label62.Text = strReceive[3];
            this.label61.Text = strReceive[4];
            this.label60.Text = strReceive[5];
            this.label59.Text = strReceive[6];
            this.label58.Text = strReceive[7];
            this.label57.Text = strReceive[8];
            this.label56.Text = strReceive[9]; 
        }
        public void LongTask2(object obj)
        {
            string[] strReceive = new string[10];            strReceive = c.receive();            this.label53.Text = strReceive[0];
            this.label52.Text = strReceive[1];
            this.label51.Text = strReceive[2];
            this.label50.Text = strReceive[3];
            this.label49.Text = strReceive[4];
            this.label48.Text = strReceive[5];
            this.label47.Text = strReceive[6];
            this.label46.Text = strReceive[7];
            this.label45.Text = strReceive[8];
            this.label44.Text = strReceive[9];
        }问题：如何通过队列，或者锁，对他们响应的数据进行异步处理。
      现在的结果是响应回来的数据，不能异步显示，会产生交叉显示。
      如： this.label65.Text =60，......
           this.label53.Text =50，......
      会出现这样的结果：
           this.label65.Text =50，......
           this.label53.Text =60，......

Answer 1

已用简单方法解决了下，，，，能达到我的要求，殊不知：稳定否？//定时发送请求(读T1-T10：Actual)
        private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            lock (this)
            {
                c.send("09 20 00 0A", "03");//发送请求指令
                ReciveData1();
            }         
          
        }
        private void timer2_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            lock (this)
            {
                c.send("09 34 00 0A", "03");//发送请求指令          
                ReciveData2();            
            }
        }

Answer 2

用一个计时器：
     //启动时钟，发送数据
            System.Windows.Forms.Timer timer1 = new System.Windows.Forms.Timer();
            timer1.Tick += new EventHandler(timer1_Elapsed);
            //timer1.Elapsed += new System.Timers.ElapsedEventHandler(timer1_Elapsed);
            timer1.Interval = 1000;//毫秒            timer1.Enabled = true;
 private void timer1_Elapsed(object sender, EventArgs e)
        {
            //lock (this)
            //{
            //    c.send("09 20 00 0A", "03");//发送请求指令 (读T1-T10：Actual)
            //    ReciveData1();
            //    Thread.Sleep(1000);
            //}
            lock (this)
            {
                c.send("09 20 00 0A", "03");//发送请求指令 (读T1-T10：Actual)
                LongTask1();
                c.send("09 34 00 0A", "03");//发送请求指令    (读T1-T10：Setpoint)       
                LongTask2();
                c.send("09 48 00 0A", "03");//发送请求指令 (读1B-10B：Actual)
                LongTask3();
                c.send("09 5C 00 0A", "03");//发送请求指令 (读B1-B10：Setpoint)
                LongTask4();            }        }
