主要核心使用.Net Silverlight SDK的类库中委托语言如（C#）的动态创建控件方法，在初始化时调用了LoadXaml方法，并且使用System.Windows.Markup.XamlReader方法读取Xaml数据并创建对象，并使用this.LayoutRoot.Children.Add添加了创建的对象控件：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.IO;
using System.Windows.Markup;
public partial class Page : UserControl
{
public Page()
{
InitializeComponent();
this.LoadXaml();
}
private const string xaml =
"<Rectangle xmlns=\"http://schemas.microsoft.com/client/2007\" Width=\"20\" Height=\"40\" Stroke=\"#808080\" StrokeThickness=\"1.5\" RadiusX=\"2\" RadiusY=\"2\" Opacity=\"1\">" +
"<Rectangle.Fill>" +
"<LinearGradientBrush StartPoint=\"0.5,0\" EndPoint=\"0.5,1\" >" +
"<GradientStop Color=\"#0076E0\" Offset=\"0.0\" />" +
"<GradientStop Color=\"#0046B0\" Offset=\"1.0\" />" +
"</LinearGradientBrush>" +
"</Rectangle.Fill>" +
"</Rectangle>";
public void LoadXaml()
{
Rectangle rect = XamlReader.Load(xaml) as Rectangle;
this.LayoutRoot.Children.Add(rect);
}
}// end for method
