Question

Suppose we have WPF element, in code we add content/controls to it.
How do we get the generated content as XAML?

for example in XAML we have:

In code behind:

  pLines.Points.Add(new Point(10, 140));
        pLines.Points.Add(new Point(270, 140));
        pLines.Points.Add(new Point(270, 220));
        pLines.Points.Add(new Point(255, 220));
        pLines.Points.Add(new Point(230, 175));
        pLines.Points.Add(new Point(205, 220));

Now how to get the generated XAML after the code behind is executed?

Answer 1

You can use the XamlWriter class.

var pLines = new Polyline();
pLines.Points.Add(new Point(10, 140));
pLines.Points.Add(new Point(270, 140));
pLines.Points.Add(new Point(270, 220));
pLines.Points.Add(new Point(255, 220));
pLines.Points.Add(new Point(230, 175));
pLines.Points.Add(new Point(205, 220));
string asXaml = XamlWriter.Save(pLines);
//<Polyline Points="10,140 270,140 270,220 255,220 230,175 205,220" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" />
