无论分辨率如何，Winform在屏幕上的大小和位置

I have a winform (c#, let's say 250px by 250px) that needs to stay in one location on the screen regardless of screen resolution i.e 800x600, 1920x1080 etc. The Winform itself contains only one element - a picturebox so what's inside really doesn't matter (no need to worry about fonts, etc.). I just need it to stick in one place on the screen from one monitor to another.I have a winform (c#, let's say 250px by 250px)
