How to "Dequeue" Element from a List?

Question

I have a List of cards called _deck:

 private List<String> _deck = new List<String> {"2h", "3h", "4h", ... } 

And then I want to remove a card from the List and save into a variable. I'm trying to do:

 String p1FirstCard = _deck.RemoveAt(0); 

but I'm getting the error

Cannot convert type void to String

In C# List is there something like push/pop but which does that at the "head" or "start" of the List? (Push/pop works at the "tail" or "end" of the list.)

If not, how should I do remove the first element but save it in a variable?

If you want to dequeue the first element, you could simply use a Queue<T>.

class Program {     static void Main(string[] args)     {         var _deck = new Queue<String>();         _deck.Enqueue("2h");         _deck.Enqueue("3h");         _deck.Enqueue("4h");         _deck.Enqueue("...");          var first = _deck.Dequeue(); // 2h         first = _deck.Dequeue(); // 3h     } } 

If you want to pop the last element, you could use a Stack<T>.

class Program {     static void Main(string[] args)     {         var _deck = new Stack<String>();         _deck.Push("2h");         _deck.Push("3h");         _deck.Push("4h");         _deck.Push("...");          var first = _deck.Pop(); // ...         first = _deck.Pop(); // 4h     } }
