How WPF displays binary picture data from a database on an image control

First, define an image control in a XAML file named img

MemoryStream stream = new MemoryStream (acquired database object);

BitMapImage bmp = new BitMapImage ();

Bmp. BeginInit ();//initialization

Bmp. Streamsource = stream;//Set source

Bmp. EndInit ();//Initialization end

Img. Source = bmp;//Set Image source

Many people do not initialize the BitmapImage with this method, which will result in errors and not get the image data properly.

public class EMP

{

Public byte[] Photo{set;get;}

}

Code in XAML

private void Btnchoosephoto_click (object sender, RoutedEventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog ();//Open the Select File window
Ofd. Filter = "jpg|*.jpg|png|*.png";//Filters
if (OFD. ShowDialog () = = True)
{
String fileName = Ofd. filename;//get the full path to the file
Emp. Photo = File.readallbytes (fileName);//store the binary data of the image in the photo property of the EMP
Img. Source = new BitmapImage (new Uri);//Display the picture on the image control
}
}
