winform 多个计时器操作问题

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，......
