Holding derived class list objects in Base class list object

Question

How to hold Derived class list objects in Base class list object

class Base 
{
}

class Child : Base 
{
}

Base obj = new Child();

Will the same work for list.

List<Base> obj = new List<Child>();

This is giving me error, what is the best way to achive this.

Next line: `obj.Add(new SomeOtherClassInheritingFromBaseThatIsntChild())` - do you see the problem? — Damien_The_Unbeliever, Dec 31 '15 at 07:28

Just because Child and Base have an implicit conversion, doesn't mean List<Child> and List<Base> do as these are now List<> objects.

List<Base> = (List<Base>)(new List<Child>())

You need to cast the child list to the parent list.

That cast won't work. – Damien_The_Unbeliever Dec 31 '15 at 07:28
You're right. Would he have to define his own? – AustinWBryan Dec 31 '15 at 07:42
