Telling if a class implements a specific interface

[Brian Henry]

Is there any way to tell if a class implements a specific interface such as
IComparable for example? thanks

If you have an instance of the class:

\\\
If TypeOf foo Is IComparable Then
...
End If
///

If you don't have an instance, 'GetType(Foo).GetInterface(...)'.

Yes - you can do that using reflection.

look at the GetInterfaces method of the 'Type' class. It will return an
array of 'Type' objects representing all the interfaces either implement or
inherited by a given type.

hope this helps..

Brian,
To check for a specific interface you can use:

GetType(IComparable).IsAssignableFrom(GetType(SomeClass))

Hope this helps
