推荐答案

尝试将所有儿童图片绘制为父图片!!

Try draw all child picture to parent picture!!

void ParentPictureBox_Paint(object sender, PaintEventArgs e)
{
    Graphics g = e.Graphics;

    var controls = this.ParentPictureBox.Controls.OfType<PictureBox>();
    foreach (var c in controls)
    {
        g.DrawImage(c.Image, c.Location.X, c.Location.Y, c.Width, c.Height);
    }
}

这是结果！

只是将背景设置为transparaent

pictureBox.BackColor = Color.Transparent;
