Are Action and Action<T> completely different? : <p>I want to check <code>if (obj is Action)</code> but don't know its parameters?</p>

<p>so I want to execute this code whether the obj is <code>Action</code>, <code>Action&lt;string&gt;</code>, or
<code>Action&lt;sting, int, bool&gt;</code>.. etc.</p>

<pre><code>if(obj is Action)
{
   //..
}
</code></pre>
