Transparent picturebox

Question

I'm trying to add an icon to a Win Forms project, but I can't get the transparency working. I've tried with several different images but I'm not able to set the background color to blue.

What am I doing wrong?

Answer 1

Change back color of picturebox to Color.Transparent.

You can also try to use png file with transparency channel.

Answer 2

如前所述，PictureBox是透明的，您需要使用透明图像（例如PNG）。
