Question

Basically I am inserting an image using the listviews inserting event, trying to resize an image from the fileupload control, and then save it in a SQL database using LINQ.

I found some code to create a new bitmap of the content in the fileupload control, but this was to store it in a file on the server, from this source, but I need to save the bitmap back into the SQL database, which I think I need to convert back into a byte[] format.

So how do I convert the bitmap to a byte[] format?

If I am going about this the wrong way I would be grateful it you could correct me.

Here is my code:

            // Find the fileUpload control             string filename = uplImage.FileName;              // Create a bitmap in memory of the content of the fileUpload control             Bitmap originalBMP = new Bitmap(uplImage.FileContent);              // Calculate the new image dimensions             int origWidth = originalBMP.Width;             int origHeight = originalBMP.Height;             int sngRatio = origWidth / origHeight;             int newWidth = 100;             int newHeight = sngRatio * newWidth;              // Create a new bitmap which will hold the previous resized bitmap             Bitmap newBMP = new Bitmap(originalBMP, newWidth, newHeight);              // Create a graphic based on the new bitmap             Graphics oGraphics = Graphics.FromImage(newBMP);              // Set the properties for the new graphic file             oGraphics.SmoothingMode = SmoothingMode.AntiAlias;             oGraphics.InterpolationMode = InterpolationMode.HighQualityBicubic;              // Draw the new graphic based on the resized bitmap             oGraphics.DrawImage(originalBMP, 0, 0, newWidth, newHeight);                PHJamesDataContext db = new PHJamesDataContext();              System.IO.MemoryStream stream = new System.IO.MemoryStream();             newBMP.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);             stream.Position = 0;             byte[] data = new byte[stream.Length];              PHJProjectPhoto myPhoto =                 new PHJProjectPhoto                 {                     ProjectPhoto = data,                     OrderDate = DateTime.Now,                     ProjectPhotoCaption = ProjectPhotoCaptionTextBox.Text,                     ProjectId = selectedProjectId                 };              db.PHJProjectPhotos.InsertOnSubmit(myPhoto);             db.SubmitChanges();

You should be able to change this block to

        System.IO.MemoryStream stream = new System.IO.MemoryStream();         newBMP.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);          PHJProjectPhoto myPhoto =             new PHJProjectPhoto             {                 ProjectPhoto = stream.ToArray(), // <<--- This will convert your stream to a byte[]                 OrderDate = DateTime.Now,                 ProjectPhotoCaption = ProjectPhotoCaptionTextBox.Text,                 ProjectId = selectedProjectId             };
