Generics in c#: "two levels of indirection"

Question

Hi,

There is a piece of code that I would implement like this in java:

public void doIt( T extends MyEventArgs<? extends MyBaseClass> obj ) {
   ...
}

How would I do that in c#? I first thought this would be it:

public void oIt( T obj ) where T : MyEventArgs<P> where P : MyBaseClass {
    ...
}

But apparantly my syntax is wrong.

any ideas?

PS: don't ask me why I'm doing this. Please :)

Answer 1

Just missing the generic type arguments:

public void oIt<T,P>( T obj )
     where T : MyEventArgs<P>
     where P : MyBaseClass
{
     ...
}

(the names oIt, T, P and obj could probably be clearer, but I'll assume that is anonymisation)
