[Reprinted] Key Points of transparent control settings in winform

I usually do not use it much. I have forgotten it for three times, so I have to go online every time and write it to my blog as a record.
Basic Theory:
The background color of a widget is often inherited from the parent widget.

Label1.parent = picturebox1; // set the parent control of the label to picturebox.
Label1.backcolor = color. Transparent; // set the background to transparent.
