what happens if default value is null and convert to string
<p>to be more specific, I have DateTime? BirthDate</p>

<p>my question is what will happen in this case:</p>

<pre><code>lblBirthDate.Text = myObject.BirthDate.GetValueOrDefault().ToString();
</code></pre>

<p>if BirthDate will be null. I have resharper installed, and it doesn't warn me that I could have a null problem there...</p>
