How to flatten the list of array in Lambda expression

Question

I am writing a lambda expression to get all types of classes, which are implemented some specific interface types, from AppDomain.CurrentDomain.GetAssemblies(). I am using the below Lambda expression to find the result. But the problem is, I am getting a Collection of array like IEnumerable<Type[]>. But I need it like just IEnumberable. How do I flatten the this result.

var types = AppDomain.CurrentDomain.GetAssemblies().Where(t => t.GetType().GetInterfaces()
                .Any(type => type.IsGenericType && type.GetGenericTypeDefinition() == typeof (IMyInterface<,>)))
                .SelectMany(a => a.GetTypes());

Answer 1

Instead of using Select statement, use SelectMany(). That will flatten your result. Try below code.

var types = AppDomain.CurrentDomain.GetAssemblies().Where(t => t.GetType().GetInterfaces()
                .Any(type => type.IsGenericType && type.GetGenericTypeDefinition() == typeof (IMyInterface<,>)))
                .SelectMany(a => a.GetTypes());
