C# - Detect PictureBox overlap

问题

Is it possible to detect if a pictureBox is colliding with/overlapping with another pictureBox? Sorry for the vague question formulation.

回答1:

To check if 2 rectangles overlapped you can use IntersectsWith:

bool overlapped= pictureBox1.Bounds.IntersectsWith(pictureBox12.Bounds);

To find the intersection area you can use Rectangle.Intersect:

Rectangle intersectionArea = Rectangle.Intersect(pictureBox1.Bounds, pictureBox2.Bounds);

回答2:

You can use Rectangle.Intersect.
Just give Bounds of both PictureBoxes to the method:

Rectangle unionRect = Rectangle.Intersect(pictureBox1.Bounds, pictureBox2.Bounds);
if (unionRect.IsEmpty) {
    // no intersecion
}
