title: Assign null to empty instance?
body: <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>
