史上最简洁C# 生成条形码图片思路及示例分享

            img = new Bitmap(intWidth, intHeight);
            g = Graphics.FromImage(img);
            g.Clear(Color.White);
            g.CompositingQuality = CompositingQuality.HighQuality;
            g.SmoothingMode = SmoothingMode.HighQuality;
            g.DrawString(strNumber, font, Brushes.Black, 0, 0);
            MemoryStream stream = new MemoryStream();
            img.Save(stream, ImageFormat.Jpeg);
            HttpContext.Current.Response.ClearContent();
            HttpContext.Current.Response.ContentType = "image/Jpeg";
            HttpContext.Current.Response.BinaryWrite(stream.ToArray());
            g.Dispose();
            img.Dispose();
        }
