The TransparencyKey should be a color on the background image, not a color on the form itself. TransparencyKey应该是背景图片上的颜色，而不是表单本身上的颜色。 So you can't set the TransparencyKey to the form's BackColor since the form is not its own background image. 因此，您不能将TransparencyKey设置为表单的BackColor因为表单不是它自己的背景图像。
It's been a very long time I read it but I'll post a reference link as I've found it. 我已经读了很长时间，但是找到后我会发布一个参考链接。 It's on MSDN, I believe. 我相信它在MSDN上。
