How do I convert a Bitmap to byte[]?

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.<

Answer 1

If you've got a MemoryStream already, just call MemoryStream.ToArray to get the data out.

Answer 2

Assuming, that your bitmap is bmp

byte[] data;
using(System.IO.MemoryStream stream = new System.IO.MemoryStream()) {
   bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);
   stream.Position = 0;
   data = new byte[stream.Length];
   stream.Read(data, 0, stream.Length);
   stream.Close();
}

Answer 3

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
            };
