Question

If an object inherit from an abstract class that inherite from an interface will the object inherit from the interface ?

Will this interface can be used with Dependency Injection Container ?

Thanks.

Answer 1

Yes it does implement that interface and since this is true it can be injected as a dependency.

Here is a quick test that proves the interface implementation:

using System;

interface IParent {}
abstract class Parent : IParent {}

class Example : Parent
{
    static void Main()
    {
        Console.WriteLine(new Example() is IParent);
    }
}
