c# - WPF Image to byte[]

Question

I'm trying to convert from System.Windows.Controls.Image to byte[] and I didnt know which method from Image class could help in this scenary, by the way I really dont know what should I do, cause in my LINQ model the field appears as Binary type, I have to change this if I want to save it like a byte[] type?

I found code posted here, but without using WPF:

Bitmap newBMP = new Bitmap(originalBMP, newWidth, newHeight);
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
};

Real Solution... if want to save jpg images from an System.Windows.Control.Image when your database mapped field on your ORM is Byte[] / byte[] / Bynary

public byte[] getJPGFromImageControl(BitmapImage imageC)
{
       MemoryStream memStream = new MemoryStream();              
        JpegBitmapEncoder encoder = new JpegBitmapEncoder();
        encoder.Frames.Add(BitmapFrame.Create(imageC));
        encoder.Save(memStream);
        return memStream.ToArray();
}

call as :

getJPGFromImageControl(firmaUno.Source as BitmapImage)

Hopes helps :)
