推荐答案

尝试使用半透明笔刷绘制一个填充的矩形:

Try drawing a filled rectangle with a semi transparent brush:

SolidBrush semiTransparentBrush = new SolidBrush(Color.FromArgb(90, 255, 0, 0)); // 90 is the alpha value (range goes from 0 - completely transparent, 255 - solid)
image.FillRectangle(semiTransparentBrush, 0, 0, image.Width, image.Height);

祝你好运！

Good luck!
