c# - How to check type parameter?

Question

I have class

class ManagerCar : IBlalba
{
   public void Render(IViewTemplate template)
   {
   }
}

and I know what the parameter template is CarViewTemplate I want check type and throw exception if IViewTemplate != CarViewTemplate

I can do check if(template is typeof(CarViewTemplate)).

But I have many Managers.

I want check this type on compilation and with help attribute like [IsType(typeof(CarViewTemplate))]

Is it possible ?

UPDATE I have interface with Render(IViewTemplate template)

Answer 1

This type of check already exists in the compiler, no need to try to help it.

Simply change your method signature to this:

public void RenderCar(CarViewTemplate template)
