How identify object by Interface type

[moondaddy]

I'm writing a .net3.0 WPF app in c# and want to determin if an object
implements a certain interface something like this:

UIElement elem = GetObjectClicke d(e.source as DependancyObjec t)

if(elem.type==I Selectable)
{
return elem;
}

Where ISelectable is the interface I'm looking for. In otherwords, how do I
determin if 'elem' implements ISelectable?

Thanks

You can also use Type.IsAssignab leFrom (if you have the type but not the
object ref)
