What is the integer reference type in C#?
<p>I'd like to have an integer variable which can be set to null and don't want to have to use the <code>int? myVariable</code> syntax. I tried using <code>int</code> and <code>Int16</code> to no avail. Do I have to use <code>int? myVariable</code>?</p>

<p>I mentioned this because in Java there is both an 'int' type (a primitive) and 'Integer' (a reference type). I wanted to be sure that there isn't a built-in integer reference type that I could be using. I'll use 'int?' for what I'm doing.</p>
