ExportToImage for saving diagram's image in database

[Egemen]

Hi,

I'd like to export and save the image of diagram in database.
I try to do this...

 Byte[] bytes = null;
            using (var stream = new MemoryStream())
            {
                diagram.ExportToImage(stream, null, new Rect(0, 0, 400, 400), new Size(200, 200), backgroundBrush: new     SolidColorBrush(Colors.White));
                bytes = new Byte[stream.Length];
                stream.Read(bytes, 0, bytes.Length);
            }

Here is the result   0x000000000000000000000000000000000000......................................

Thank you

Hello Egemen,

 You have to re-position the Stream to its beginning before reading it or you can use some special StreamReader for example.

Byte[] bytes = null;
            using (var stream = new MemoryStream())
            {
                TemplateEditorDiagram.ExportToImage(stream, null, new Rect(0, 0, 400, 400), new Size(200, 200), backgroundBrush: new SolidColorBrush(Colors.White));
                bytes = new Byte[stream.Length];
                stream.Position = 0;
                stream.Read(bytes, 0, bytes.Length);
            }
