title: C# pass parameters to event handler
body: <p>A question that has come to my mind. Let's say I want to pass a variable theVar to the event handler declaration below</p>
  
  <pre><code>new EventHandler&lt;AsyncCompletedEventArgs&gt;(evHandler)
  </code></pre>
  
  <p>and receive it in the definition below:</p>
  
  <pre><code>public void evHandler(object sender, EventArgs e)
  {
  }
  </code></pre>
  
  <p>How do I proceed?</p>
