C# elegant way to check if a property's property is null
<p>In C#, say that you want to pull a value off of PropertyC in this example and ObjectA, PropertyA and PropertyB can all be null.</p>

<p>ObjectA.PropertyA.PropertyB.PropertyC</p>

<p>How can I get PropertyC safely with the least amount of code?</p>

<p>Right now I would check:</p>

<pre><code>if(ObjectA != null &amp;&amp; ObjectA.PropertyA !=null &amp;&amp; ObjectA.PropertyA.PropertyB != null)
{
// safely pull off the value
int value = objectA.PropertyA.PropertyB.PropertyC;
}
</code></pre>

<p>It would be nice to do something more like this (pseudo-code).</p>

<pre><code>int value = ObjectA.PropertyA.PropertyB ? ObjectA.PropertyA.PropertyB : defaultVal;
</code></pre>

<p>Possibly even further collapsed with a null-coalescing operator.</p>

<p><strong>EDIT</strong> Originally I said my second example was like js, but I changed it to psuedo-code since it was correctly pointed out that it would not work in js.</p>

<p>Thanks much,
Jon</p>
