How can I know which method called event handler
<p>I have two methods:</p>

<pre><code>private void RvListen_OPT()

private void RvListen_FUT()
</code></pre>

<p>On a certain event, both call:</p>

<pre><code>void OnRvMessageReceived(object sender, SigRvMessageEventArgs args)
</code></pre>

<p>When OnRvMessageReceived is called, how can I check which of the two methods called it? I know it can be done using the object sender, but I'm not sure how to do it.</p>
