ImplementationCode:

Copy code The Code is as follows: // <summary>
2 // execute the specified expression after the specified time
3 /// </Summary>
4 /// <Param name = "interval"> time elapsed between events (in milliseconds) </param>
5 /// <Param name = "action"> expression to be executed </param>
6 public static void setTimeout (double interval, action Action)
7 {
8 system. Timers. Timer timer = new system. Timers. Timer (interval );
9 timer. elapsed + = delegate (Object sender, system. Timers. elapsedeventargs E)
10 {
11 timer. Enabled = false;
12 action ();
13 };
14 timer. Enabled = true;
15}
16 /// <summary>
17 // execute the specified expression repeatedly in the specified time period
18 /// </Summary>
19 /// <Param name = "interval"> time elapsed between events (in milliseconds) </param>
20 /// <Param name = "action"> expression to be executed </param>

Because system. timers. timer is "server-based timer is designed for auxiliary threads in a multi-threaded Environment". Therefore, you should pay attention to it if you want to modify the UI object during use in winform, here is an example used in winform:
