CodePudding user response:

And ask why baidu to the example they are to create static Task
The static Task no horse directly

CodePudding user response:

 public partial class Form1: Form 
{
Public _click () 
{
InitializeComponent (); 
Non-static A=new non-static (); 
A. method (1); 
} 

} 
The class non-static 
{
Public void method (1) 
{
New Thread (the delegate () 
{
//you to execute method 
}). The Start (); 
} 
} 

So I can

CodePudding user response:

Do not need new static class, life period of the program is run (singleton), there is only one instance can be used directly,
Non-static class need generated after the new instance (object) to use,
Task not provided must use a static class, class is generally used like this:
Task t1=new Task (Open);//the Open is you the Open method
T1. Start ();

//wait for 10 seconds
System. Threading. Thread. Sleep (10 * 1000);

Task t2=new Task (Close);//Close is your Close method
T2. Start ();
