Assign null to empty instance?
<p>I have an empty instance of an object which I assign values under certain conditions. If those conditions are not met I assign null to the instance, like the following:</p>

<pre><code>SomeCustomClass someCustomClass = new SomeCustomClass();
if (myItem != null)
{
    someCustomClass.Id = myItem.Id;
}
else
{
    someCustomClass = null;
}
</code></pre>

<p>If <code>myItem</code> is null is it appropriate to assign null to someCustomClass?</p>
