Using "this" - many instances of class, calling private method
<p>I have a server where every connected client is represented by an instance of client class. This class is responsible for data processing. I always thought that when calling private function even when there are more instances of the same class, I dont need to use "this" keyword because its considered as local call, also:</p>

<pre><code>if (data[1]==2 &amp;&amp; data [3]==2)
   SendAck();
</code></pre>

<p>But when there were more players (more client classes), sometimes the message was sent to another player and the same with other methods. All was OK when I added "this" to all methods call. Is it possible that wihout "this" it calls method from some other class?
Thanks!</p>

<p>EDITL: What about using public members like public dictionary in each instance and then not using this keyword /like when calling TryGetValue/?</p>
