Hi, I am trying to resize an image in a folder. The code am using is this

string logoUrl = HttpContext.Current.Server.MapPath("DeviceLogo");
                System.Drawing.Image SourceLogo = System.Drawing.Image.FromFile(logoUrl + @"\" + objDevice.FileName);

                //Create a logo for this device and reseller/client business              
                Bitmap newImage = new Bitmap(objDevice.LogoWidth, objDevice.LogoHeight, PixelFormat.Format24bppRgb);
                using (Graphics graphics = Graphics.FromImage(newImage))
                {
                    graphics.CompositingQuality = CompositingQuality.HighQuality;
                    graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
                    graphics.SmoothingMode = SmoothingMode.HighQuality;
                    graphics.DrawImage(SourceLogo, 0, 0, objDevice.LogoWidth, objDevice.LogoHeight);
                }
                string filepath = HttpContext.Current.Server.MapPath("DeviceLogo");                

                //Save the resized image
