WPF 碰撞检测

have tested this, it worked, at least for me

var x1 = Canvas.GetLeft(e1);

var y1 = Canvas.GetTop(e1);

Rect r1 = new Rect(x1, y1, e1.ActualWidth, e1.ActualHeight);

var x2 = Canvas.GetLeft(e2);

var y2 = Canvas.GetTop(e2);

Rect r2 = new Rect(x2, y2, e2.ActualWidth, e2.ActualHeight);

if (r1.IntersectsWith(r2))

    MessageBox.Show("Intersected!");

else

    MessageBox.Show("Non-Intersected!");

ar ellipse1Geom = ellipse1.RenderedGeometry;

var ellipse2Geom = ellipse2.RenderedGeometry;

var detail = ellipse1Geom.FillContainsWithDetail(ellipse2Geom);

if(detail != IntersectionDetail.Empty)

{

    // We have an intersection or one contained inside the other

}

The Geometry.FillContainsWithDetail(Geometry) method is defined as

Returns a value that describes the intersection between the current geometry and the specified geometry.
