Yield Return with Null
<p>Is there any way to optionally return a null with a "return yield" driven iterator?</p>

<p>I would like to return a null in some cases and I don't think this is particular to IEnumerable of type string. Same goes for IEnumerable of type int etc. Thanks</p>

<pre><code>static void Main(string[] args)
{
    var Items = GetItems();

    if (Items != null)
    {
        foreach (var item in Items)
        {
            Console.WriteLine(item);
        }
    }
    else
    {
        Console.WriteLine("&lt;null&gt;");
    }
}

static IEnumerable&lt;string&gt; GetItems()
{
    if (false)
    {
        yield return "Andy";
        yield return "Jennifer";
    }

    return null; // &lt;- Compiler Error:
    // Cannot return a value from an iterator. 
    // Use the yield return statement to return a value,
    // or yield break to end the iteration.
}
</code></pre>
