title: I can't get Id of some image resource in Xamarin Project?
body: <p>I am trying to get Id of image resource in drawable folder.
  <a href="https://i.stack.imgur.com/igCu6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/igCu6.png" alt="enter image description here"></a></p>
  
  <p>Here is my code.</p>
  
  <pre><code>...
  int resourceId = Context.Resources.GetIdentifier("Elements_ok", "drawable", this.context.PackageName);
  </code></pre>
  
  <p>I always got the result of Zero.
  But I got Id of image named error.png.</p>
  
  <pre><code>int resourceId = Context.Resources.GetIdentifier("error", "drawable", this.context.PackageName);
  </code></pre>
  
  <p>Is there a way that I can fix it?</p>
