我的C＃表单的不透明度值没有调整

Question

I wanted to make one of my forms opaque. I did this by changing the opacity value in the form between 0 and 100. I later wanted to change this value during run-time, so i wrote some code:

Opacity = 80;

However my form doesn't seem to change opacity. Does anyone know what i'm doing wrong.

Answer 1

Form.Opacity属性的范围是0到1。因此，要达到80％的不透明度，您可以编写Opacity = 0.8
