title: WPF Canvas Is rectangle at position
body: <p>How can I check if a rectangle object is at a specific position in a canvas? The only solution I found is going through all children in the canvas and check if their position matches, but I don't think that is a good solution. </p>
  
  <p>So I need something like <code>Canvas.IsRectangleAtPosition(Point x)</code>, is there anything like that? </p>
  
  <p>If not, how can I implement such a method?</p>
  
  <p>Kind regards</p>
