Shorthand for single item to collection c#
<p>I have a lot of code that takes on the following pattern</p>

<pre><code>void Add(int foo)
{
 $my question
}

void Add(List&lt;int&gt; bar)
{
//do stuff
}
</code></pre>

<p>I was wondering (other than writing an extension method) if there was something 'shorter than writing:</p>

<p><code>Add(new List&lt;int&gt;(new int[]{foo}));</code> </p>

<p>everytime I wanted to call the second method. Hoping to find a gem ive missed in the .net library.</p>
