Yield Return with Null

Question

Is there any way to optionally return a null with a \"return yield\" driven iterator?

I would like to return a null in some cases and I don\'t think this is particul

You're not using an enumerable as it was intended (to iterate objects in a collection). If you want to keep your code similar to what it is now, you should do something like this:

static void Main(string[] args)
{
    var Items = GetItems();

    foreach (var item in Items) //this will not enter the loop because there are no items in the Items collection
    {
            Console.WriteLine(item);
    }

    //if you still need to know if there were items, check the Count() extension method
    if(Items.Count() == 0)
    {
      Console.WriteLine("0 items returned");
    }


}

static IEnumerable GetItems()
{
    if (false)
    {
        yield return "Andy";
        yield return "Jennifer";
    }

    yield break;
}
