Re: implement

J-L submitted this idea :
HI,

I don't find the method ro detect if a class implement an interface.

I try

if (MyObject implements MyInterface)

but it doesn't work.

if (MyObject is MyInterface)

work. Is it the only method to do that ?

J-L
the "is" operator works with both interfaces and (base)classes.
Basically it's "can I treat 'MyObject' as a 'MyInterface'".

A different way would be the "as" operator, which tries a cast but
gives a 'null' if it didn't work:
MyInterface mi = MyObject as MyInterface;
if (mi != null) ...

And if you really want to, you could also use reflection.
