//加边框
try

Bitmap Backbmp = new Bitmap(@"" + Path);
float w = (float)(Backbmp.Width * 0.2);
using (Graphics g = Graphics.FromImage(Backbmp))
{
using (Brush brush = new SolidBrush(Color.FromArgb(0, 156, 255)))
{
using (Pen pen = new Pen(brush, w))
{
pen.DashStyle = DashStyle.Custom;

pic.BackgroundImage = Backbmp;
}
}
}
}
