C# quickest way to shift array

Question

How can I quickly shift all the items in an array one to the left, padding the end with null?

For example, [0,1,2,3,4,5,6] would become [1,2,3,4,5,6,null]

Couldn't you use a System.Collections.Generic.Queue instead of an array ?

I feel like you need to perform actions on your value the discard it, thus using a queue seems to be more appropriate :

// dummy initialization
        System.Collections.Generic.Queue queue = new Queue();
        for (int i = 0; i < 7; ++i ) { queue.Enqueue(i); }// add each element at the end of the container

        // working thread
        if (queue.Count > 0)
            doSomething(queue.Dequeue());// removes the last element of the container and calls doSomething on it
