Define a class MyClass<T> or a function MyFunction<T>(T x) where T can only by a type that implements IMyInterface

Question

I want to define a class MyClass<T> and a very particular function MyFunc<T> , but I want to force T to inherit from (in any way) an interface or a class. Let's call this IMyInterface .

The only way my knowledge of C# allows me to do this is to define a generic class, check if it inherits (see How do I check if a type is a subtype OR the type of an object? for example), and throw an exception otherwise.

Is there a way to force this at compile-time, rather than runtime?

Answer 1

Generic type constraints:

public void MyFunc<T>() where T : IMyInterface {
}
