Question

If I have a method with a parameter that’s an interface, whats the fasts way to see if the interface’s reference is of a specific generic type?

More specifically, if I have:

interface IVehicle{}  class Car<T> : IVehicle {}  CheckType(IVehicle param) {     // How do I check that param is Car<int>? } 

I’m also going to have to cast after the check. So if there is a way to kill 2 birds with one stone on this one let me know.

Answer 1

To check if param is a Car<int> you can use ‘is’ and ‘as’ as normal:

CheckType(IVehicle param) {     Car<int> car = param as Car<int>;     if (car != null)     {          ...     } }
