Error While Uploading the image.

Hi,

  Use "using System.Drawing;"  and try following code. Here am using photo upload using XML. You can change this as Database

Code :

if (FUfile.PostedFile.ContentLength > 0)
                        {
                            FUfile.SaveAs(Server.MapPath("~/Admin/Content/classphotos/Large/" + FUfile.FileName));
                            String imageUrl = FUfile.FileName;
                            ss = "SS" + FUfile.FileName;
                            imageUrl = "~/Admin/Content/classphotos/Large/" + imageUrl;
                            System.Drawing.Image image1 = System.Drawing.Image.FromFile(Server.MapPath(imageUrl));


                            var newWidth = 800;

                            var newHeight = 500;

                            var thumbnailBitmap = new Bitmap(newWidth, newHeight);



                            var thumbnailGraph = Graphics.FromImage(thumbnailBitmap);

                            thumbnailGraph.CompositingQuality = CompositingQuality.HighQuality;

                            thumbnailGraph.SmoothingMode = SmoothingMode.HighQuality;

                            thumbnailGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;

                            String MyString = ss;

                            var imageRectangle = new Rectangle(0, 0, newWidth, newHeight);

                            thumbnailGraph.DrawImage(image1, imageRectangle);

                            string tostream = Server.MapPath("~/Admin/Content/classphotos/Large/" + MyString);

                            thumbnailBitmap.Save(tostream, image1.RawFormat);

                            thumbnailGraph.Dispose();

                            thumbnailBitmap.Dispose();

                            image1.Dispose();
                            filenodelarge.InnerText = ss;

                        }
