Hi,

I am creating an image file using the code below

Bitmap newImage = new Bitmap(Convert.ToInt32(dtDevice.Rows[0]["LogoWidth"]), Convert.ToInt32(dtDevice.Rows[0]["LogoHeight"]));

                                       using (Graphics gr = Graphics.FromImage(newImage))
                                       {
                                           gr.SmoothingMode = SmoothingMode.AntiAlias;
                                           gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
                                           gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
                                           gr.DrawImage(SourceLogo, new Rectangle(0, 0, Convert.ToInt32(dtDevice.Rows[0]["LogoWidth"].ToString()), Convert.ToInt32(dtDevice.Rows[0]["LogoHeight"].ToString())));
                                       }

                                       fileName = dr["DeviceID"].ToString() + "_" + objBusiness.ID + "_" + objBusiness.ResellerId + imgExtension;

                                       //Save the resized image
                                       newImage.Save(filePath + fileName);

The save method saves the file in the specified folder. But before saving i want to get the raw data of the image . Currently am doing this

FileInfo fileInfo = new FileInfo(tempFilePath + fileName);
                                       byte[] fileData = new byte[fileInfo.Length];
                                       DataTable dtBusiness = new Businesses().GetBusiness(objBusiness.ID);
                                       if (dtBusiness != null && dtBusiness.Rows.Count > 0)
                                       {
                                           httpUserName = dtBusiness.Rows[0]["httpUserName"].ToString();
                                           httpPassword = dtBusiness.Rows[0]["httpPassword"].ToString();
                                       }
                                       fileData = File.ReadAllBytes(filePath + fileName);

                                       using (FileStream fs = new FileStream(filePath + fileName, FileMode.Open, FileAccess.Read))
                                       {
                                           fileData = new byte[fs.Length];
                                           fs.Read(fileData, 0, Convert.ToInt32(fs.Length));
                                           fs.Close();
                                       }
                                       imageContent = Convert.ToBase64String(fileData);

so that image content will be a base64String.But the problem is that to read the file bytes i have to save it which i want to skip.

Is it possible to get it before saving in the folder?Thanks in advance
