Check if Object implements an Interface?

[Lucas Tam]

Hi all,

I like to dynamically check if an object implements a particular interface.

Currently I am doing:

Ctype(Object, IInterface)

If the object implements the interface it will not throw an error... Is
there a better way I can do this via System.Reflecti on?

Thanks!

Why do you want to use Reflection? The easiest way is

If TypeOf obj is IInterace Then

I suggest to use 'TypeOf...Is' when possible.

Oh Ha Ha... I didn't think TypeOf would check it's interfaces... I always
thought TypeOf only checked it's object type : )
