About to get the return value from a method called by a delegate

[Jet Leung]

Hi all,
I had made a method that will return a string type value. And I invoke this
method in a string type delegate .And how can I get the return value when
the method finish processing.
for example:
public string A()
{
...
return A_value;
}
public class C_A
{
delegate string delegate_A;
public C_A()
{
delegate_A D_A=new deleagate_A(A);
D_A.BeginInvoke(null,null);
}
}

Like this the method has a string type return value, and when I call it in a
delegate ,how can I get the return value from the method A?

The crux is that when you call endinvoke on the delegate you will get
the return value. The various ways of calling EndInvoke are described in
the articles above. Hope that clears it up.
