How to determine if a type implements an interface with C# reflection?

There are many ways to determine if a type implements an interface in C#

1) using: typeof(IMyInterface).IsAssignableFrom(typeof(MyType))

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

For a generic interface, it’s a bit different.

typeof(MyType).GetInterfaces().Any(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(IMyInterface<>))
