Form.DesktopBounds.Width似乎偏离了10个像素。 如何确定正确的表格宽度？

Question

When accessing the Form.DesktopBounds.Width property it seems to be off by 10 pixels. It also seems that the window border is 5 pixels on each side. How can I determine the correct form width, including the border around the form.

Answer 1

According to the documentation , if you want to get the size and location of the control including its nonclient elements, you just want to use Form.Bounds . In the case of width, that would be Form.Bounds.Width .

I believe my comment suggestion of Form.Width will work as well, since Top , Left , Width , and Height all come from the Bounds themselves.

Answer 2

I just ran into this problem.

I get the "off by 10" numbers from Form.Height and from Form.Bounds.Height . The height values are correct on Windows XP, but off by 10 on Windows 7. ( Width values are also off.)

When the FormBorderStyle is Sizable then the values are correct. But when it is FixedToolWindow I get the off-by-10 values.
