推荐答案

可能，您的问题是单位选择:

Probably, your problem is your unit selection:

e.Graphics.PageUnit = GraphicsUnit.Pixel;

由于像素的大小将取决于设备的输出分辨率，因此我希望大小会在设备之间发生变化.尝试改用设备独立单位:尝试改用点"，英寸"，文档"或毫米"-随便哪个.

Since the size of a pixel will be dependant on the output resolution of the device, I would expect the size to change between devices. Try using a device independant unit instead: try Point, Inch, Document or Millimeter instead - whichever you are comfortable with.
