IList to IList

Question

I have a few classes:

class Vehicle
{
}

class Car : Vehicle
{
}

I have a list of the derived class: IList cars;

Answer 1

Here are a couple of approaches using Linq:

IList list = new List();
list.Add(new Derived());

IList otherlist = new List(from item in list select item as Base);
IList otherlist2 = new List(list.Select(item => item as Base));
