c# stack queue combination

Question

is there in C# some already defined generic container which can be used as Stack and as Queue at the same time? I just want to be able to append elements either to the end,

Answer 1

Here's a class to help people implement this easily:

public class StackQueue
{
    private LinkedList linkedList = new LinkedList();

    public void Push(T obj)
    {
        this.linkedList.AddFirst(obj);
    }

    public void Enqueue(T obj)
    {
        this.linkedList.AddFirst(obj);
    }

    public T Pop()
    {
        var obj = this.linkedList.First.Value;
        this.linkedList.RemoveFirst();
        return obj;
    }

    public T Dequeue()
    {
        var obj = this.linkedList.Last.Value;
        this.linkedList.RemoveLast();
        return obj;
    }

    public T PeekStack()
    {
        return this.linkedList.First.Value;
    }

    public T PeekQueue()
    {
        return this.linkedList.Last.Value;
    }

    public int Count
    {
        get
        {
            return this.linkedList.Count;
        }
    }
}
