Using the `is` operator with Generics in C#

Question

I want to do something like this:

class SomeClass<T> {    SomeClass()    {         bool IsInterface = T is ISomeInterface;    } } 

What is the best way for something like this?

Note: I am not looking to constrain T with a where, but I would like my code to be aware of what types of interfaces T implements. I would prefer that I don't have to construct a T.

I don't think you can use the is operator for this. But you can use IsAssignableFrom:

bool IsInterface = typeof(ISomeInterface).IsAssignableFrom(typeof(T));
