Silverlight XamlWriter

我发现.Net XamlWriter在Silverlight中不可用。好吧，反正我需要一个，所以我想有一个解决办法

---

我有一些UIElement对象（路径、椭圆、矩形等等），我想存储它们的Xaml定义，以便以后可以使用XamlWriter.load（）加载它们。有什么办法吗？是否有推荐的第三方XamlWriter实现等

对于Silverlight，似乎有一些XamlWriter的实现。我所看到的看起来最严重的是Silverlight Contrib，但我正在使用的SL3还不支持它

因为我只有几个特定的对象可以从中提取xaml，所以我自己创建了相应的函数。还将进行一些重构，但这一次可以用于查找路径图的xaml—存储为InkPresenter：

    public static string ConvertPathToXaml(InkPresenter drawObject)
    {
        string xmlnsString = "http://schemas.microsoft.com/client/2007";
        XNamespace xmlns = xmlnsString;

        var strokes = new XElement(xmlns + "StrokeCollection");             

        foreach (var strokeData in drawObject.Strokes)
        {
            var stroke = new XElement(xmlns + "Stroke",
                new XElement(xmlns + "Stroke.DrawingAttributes",
                    new XElement(xmlns + "DrawingAttributes",
                        new XAttribute("Color", strokeData.DrawingAttributes.Color),
                        new XAttribute("OutlineColor", strokeData.DrawingAttributes.OutlineColor),
                        new XAttribute("Width", strokeData.DrawingAttributes.Width),
                        new XAttribute("Height", strokeData.DrawingAttributes.Height))));                        
            var points = new XElement(xmlns + "Stroke.StylusPoints");

            foreach (var pointData in strokeData.StylusPoints)
            {
                var point = new XElement(xmlns + "StylusPoint",
                    new XAttribute("X", pointData.X),
                    new XAttribute("Y", pointData.Y));
                points.Add(point);
            }
            stroke.Add(points);
            strokes.Add(stroke);
        }

        var strokesRoot = new XElement(xmlns + "InkPresenter.Strokes", strokes);
        var inkRoot = new XElement(xmlns + "InkPresenter", new XAttribute("xmlns", xmlnsString), 
            new XAttribute("Opacity", drawObject.Opacity), strokesRoot);

        return inkRoot.ToString();
    }
