Test if object implements interface

Question

What is the simplest way of testing if an object implements a given interface in C#? (Answer to this question in Java)

Answer 1

This Post is a good answer.

public interface IMyInterface {}

public class MyType : IMyInterface {}

This is a simple sample:

typeof(IMyInterface).IsAssignableFrom(typeof(MyType))

or

typeof(MyType).GetInterfaces().Contains(typeof(IMyInterface))
