推荐答案

WinForms 并不真正支持透明控件，但您可以自己制作透明控件.在这里查看我的答案.

WinForms doesn't really support transparent controls, but you can make a transparent control yourself. See my answer here.

在您的情况下，您可能应该将进度条子类化并覆盖 OnPaint 方法以在进度条上绘制文本.

In your case you should probably subclass the progress bar and override the OnPaint method to draw a text on the progress bar.
