<overview>
<p>Classes that implement <code>IDisposable</code> and have members of <code>IDisposable</code> type should
dispose those members in their <code>Dispose()</code> method.</p>

</overview>
<recommendation>
<p>Add a call to <code>m.Dispose()</code> in your <code>Dispose</code> method for each member <code>m</code> that implements <code>IDisposable</code>.</p>

</recommendation>
<example>
<p>In this example, the class <code>Bad</code> contains two disposable fields <code>stream1</code> and
<code>stream2</code>, but only <code>stream1</code> is disposed in <code>Bad</code>'s <code>Dispose()</code>
method.
</p>
<sample src="MissingDisposeCallBad.cs" />
