在WPF中以编程方式创建ControlTemplate

Polygon buttonPolygon = new Polygon();
buttonPolygon.Points = buttonPointCollection;
buttonPolygon.Stroke = Brushes.Yellow;
buttonPolygon.StrokeThickness = 2;

// create ControlTemplate based on polygon
ControlTemplate template = new ControlTemplate();
template.Childeren.Add(buttonPolygon); // This does not work! What's the right way?

//create button based on controltemplate
Button button = new Button();
button.Template = template;

所以我需要一种方法来设置我的多边形作为按钮的模板。建议?

谢谢。
