Is it possible to test whether an interface inheits another interface using reflection?

So I have the following Interface:

public interface Interface2 : Interface1
{
   //Properties here
}

and a Class like so:

public class MyClass
{
   public Interface2 MyDataAccess { get; set; }

   public void TestInheritance()
   {
        foreach (var property in typeof(MyClass).GetProperties())
        {
            var type = property.PropertyType;
            var inheritsproperty = type.IsAssignableFrom(typeof(Interface1));
            if (type is Interface1 || inheritsproperty)
            {
                //never hit
            }
        }
   }
}

and looking at it I would expect the above code to work,

But the inheritsProperty property is always false, and type is Interface1 is always false.

So is it possible to check if one interface inherits another using reflection? What am I doing wrong?
