winform timer 测试并行执行。

1，由于实际业务需要，需要设置定时执行某种活动。

如图。有四个按钮，和四个lable，还有四个timer，他们之间一一对应。但单击每一个按钮时，过两秒钟自动修改对应的label的值。

 

代码如下：

 

 1   public partial class timerTest : Form
 2     {
 3         public timerTest()
 4         {
 5             InitializeComponent();
 6         }
 7 
 8 
 9         private void SetLabelOne()
10         {
11             this.lbTime1.Text = "Time1 is called";
12         }
13 
14         private void SetLabelTwo()
15         {
16             this.lbTime2.Text = "Time2 is called";
17         }
18 
19         private void SetLabelThree()
20         {
21             this.lbTime3.Text = "Time3 is called";
22         }
23 
24         private void SetLabelFour()
25         {
26             this.lbTime4.Text = "Time4 is called";
27         }
28         private void btnTime1_Click(object sender, EventArgs e)
29         {
30             timer1.Enabled = true;
31         }
32 
33         private void btnTime2_Click(object sender, EventArgs e)
34         {
35             timer2.Enabled = true;
36         }
37 
38         private void btnTime3_Click(object sender, EventArgs e)
39         {
40             timer3.Enabled = true;
41         }
42 
43         private void btnTime4_Click(object sender, EventArgs e)
44         {
45             timer4.Enabled = true;
46         }
47 
48         private void timer1_Tick(object sender, EventArgs e)
49         {
50             SetLabelOne();
51         }
52 
53         private void timer2_Tick(object sender, EventArgs e)
54         {
55             SetLabelTwo();
56         }
57 
58         private void timer3_Tick(object sender, EventArgs e)
59         {
60             SetLabelThree();
61         }
62 
63         private void timer4_Tick(object sender, EventArgs e)
64         {
65             SetLabelFour();
66         }
67     }

 

 经过测试，这几个timer都可以独立运行，谁都不影响谁。
