Another way to understand the meaning of delegation

Code
Yes

Private VoidAA (stirng name)
{
Console. Write (name)
}

PrivateDelegeteVoidAdd (stirng name );
PrivarVoidTest (StringName, add addde)

{
Addde (name );
}

Call:

Test ("Zhoujun", AA)

You can add a method to the delegate... it will automatically call each.

 

 

 

Delegate, you can simply think of it as a method call. It is equivalent to a method ..

 

Output sender and eventarg

 

In fact, both of them can be obtained, just like on the ASPX page.

 

 

Events are used during registration... the meaning of active notification... depends on delegation ..

 

The return value and parameter of the delegate must be the same as that of the method.
