In different Windows versions, winform keeps the window size and controls unchanged.

Because different versions of Windows (such as XP and win7) have different default font sizes for different character sets of windowsProgramThe form to another environment will become larger or smaller, and the control is not arranged neatly.

Solution: Set the autoscalemode attribute of form to none (Font by default), and autosize attribute to false (false by default)

Autoscalemode attribute value:
None
Font scales based on font size (default)
DPI Scaling Based on DPI
Inherit inherits the autoscalemode of the container

By the way: Setting form autoscalemode to font and autosize to true can achieve automatic scaling of form and internal controls under different settings, but pay attention to the image scaling problem.
