How to make a program check a picture box intersects with another control?

问题

I was wondering how I could check if a picturebox intersects with another thing on the form. I know for a rectangle its:

if (rectangle.IntersectsWith(otherRectangle))

but (i know, not possible) i want to do like the above:

if (pictureBox1.IntersectsWith(pictureBox2))

Anyone know a good way to check? Also, im making a game in which you can move the picture box 1 with arrows keys, and jump with space. Thanks!

回答1:

If two controls are children of the same form or container, then you can check whether the controls overlap by getting their Bounds and calling IntersectsWith:

if (pictureBox1.Bounds.IntersectsWith(pictureBox2.Bounds))

DisplayRectangle is the wrong property to access; for a PictureBox, it returns (0, 0, Width, Height), so IntersectsWith will always return true if Width and Height are nonzero.

回答2:

If two picture boxes are within the same parent then:

pictureBox1.DisplayRectangle.IntersectsWith(pictureBox2.DisplayRectangle)
