c# – WPF Image to byte []

我正在尝试从System. Windows.Controls.Image转换为byte [],我不知道Image类中的哪个方法可以帮助这个场景,我的方式真的不知道该怎么做,因为在我的LINQ模型该字段显示为二进制类型,如果我想要保存它像一个byte []类型,我必须改变这个？

我发现这里贴了代码,但没有使用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
};

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();
}

getJPGFromImageControl(firmaUno.Source as BitmapImage)
