How to copy items from list to stack without using loop

I do have a Stack and a List. I need to copy all the items from list to stack without using loops i.e for, foreach.. etc.

Is there recommended way of doing it?

In java 1.8 Stack has a predefined method call addAll - Item will be push on to the stack

stack.addAll(list);

If you want to Pop the items in the same order as they appear in your list, then reverse your list before you create the stack from it.

var myStack = new Stack<MyObjectType>(myList.Reverse());

new Stack<T>(myListOfT)

Alternatively (without loops)

myStack.Push(myList[0]);
myStack.Push(myList[1]);
myStack.Push(myList[2]);
myStack.Push(myList[3]);
...

It's going to get pretty tedious. What's wrong with loops?

You can create a stack from anything that is IEnumerable 

var myStack = new Stack<MyObjectType>(myList);

See MSDN: http://msdn.microsoft.com/en-us/library/76atxd68.aspx

However, the stack constructor will be using a loop internally, you just don't see it.
