converting List into IEnumerable

[Wallace Turner]

Hi,

Assume the class definitions

interface IOrder { }

class Order : IOrder { }

 

I understand why this doesn't compile:

 

var list = new List<Order>();

IEnumerable<IOrder> iOrders = list; //IEnumerable<IOrder> not same type as
List<Order>!

 

So using that logic, can't understand why this *does* compile:

 

var arr = new Order[0];

IEnumerable<IOrder> iOrders = arr; //IEnumerable<IOrder> assignable from
Order[] ?

 

Cheers,

 

Wal
