How to delete Rect object after intersect in WPF?

Question

I would like to delete some Rect object after IntersectsWith another one. For example:

if (rect1.IntersectsWith(rect2))
{
    rect1.Remove()?!
}

How could I do that? Those rects are in myCanvas.Children, but I don't know how to get their index for myCanvas.Children.RemoveAt(index) .

Answer 1

Use

if (rect1.IntersectsWith(rect2))
{
    myCanvas.Children.Remove(rect1);
}

That way you don't need to find the index first.

In case you need the index use IndexOf

if (rect1.IntersectsWith(rect2))
{
    var index = myCanvas.IndexOf(rect1);
    if(index > -1)
    {
        myCanvas.Children.RemoveAt(index);
    }
}
