Create a generic list using reflection

Question

I have a function that uses reflection to set properties of object A from object B. At one point, I need to instantiate a generic collection. However, I am unable to get it work

Answer 1

You can't instantiate an interface. What you can do is instantiate a generic type that implements that interface. In your case, you'll want to get the Type representing the generic List<>, then call MakeGenericType on it.

That assumes that you know List will always work. If not, I suppose you could search for types that implement the interface, but how you'd pick one and be sure it has a parameterless constructor seems complicated to me. Seems like it would be easier to get the actual type of the object rather than the interface in that case.
