Question

I have several PathGeometry-s which are showing line between places. I want to save these lines. I couldn’t serialize it to XML and don’t know how to store these lines. Is there any chance to do it ?

[EDIT] I have PathGeometry-s at code behind, not in XAML. When i try to use XMLWriter class to store these it gives exception “… classes couldn’t be restored because they dont be known as known types “

In case you have the PathGeometry already instantiated as an object you can try to use the XAMLWriter to serialize it MSDN

e.g.

        var pathgeo = new PathGeometry();
        pathgeo.AddGeometry(new PathGeometry(new PathFigureCollection() { new PathFigure(new Point(10, 50), new List<PathSegment>() { new LineSegment(new Point(200, 70), true) }, false) }));

        // Save
        var s = XamlWriter.Save(pathgeo);

        byte[] byteArray = Encoding.ASCII.GetBytes(s);
        var stream = new MemoryStream(byteArray);

        // Load
        var ob = XamlReader.Load(stream);

        // test beeing a System.Windows.Shapes.Path
        test.Data = ob as PathGeometry;
