Iterating though an array isn’t a problem but what if I only wanted to incremented only when the method is called?

Im not even sure if this would work but is there an easier way of doing this

    int counter;
    string[] myArray = {"foo", "bar", "something", "else", "here"};

    private string GetNext()
    {
        string myValue = string.Empty;

        if (counter < myArray.Length) {
            myValue = myArray [counter];
        } else {
            counter = 0;
        }

        counter++;

        return myValue;
    }
