Question

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;
    }

What you want is an iterator

private IEnumerable<String> myEnumarable()
{
    foreach(string i in myArray)
    {
       yield return i;
    }
}

However just calling myArray.GetEnumerator(); has the same effect.

You use it by

string[] myArray = { "foo", "bar", "something", "else", "here" };
IEnumerator<String> myEnum;

private string GetNext() //Assumes there will be allways at least 1 element in myArray.
{
    if(myEnum == null)
       myEnum = myArray.GetEnnumerator();
    if(!myEnum.MoveNext())
    {
       myEnum.Reset();
       myEnum.MoveNext();
    }
    return myEnum.Current;
}
