本文详细介绍了如何使用Silverlight 3.0 和 Visual Studio 2010 创建动态启动页面，包括直接修改 App.xaml.cs 文件的方式以及通过 HTML 页面或 ASP.NET 页面添加启动参数并根据参数运行不同 xaml 文件的方法。

工具：Visual Studio 2010，Silverlight 3.0

目前知道的就2种方式。
1、直接在App.xaml.cs文件里修改当前启动的xaml
    private void Application_Startup(object sender, StartupEventArgs e)
        {
            //SilverlightControl1是新建的xaml文件名称
            this.RootVisual = new SilverlightControl1();//new MainPage();
       }

2、在.html页面或.aspx页面里添加启动参数，然后在App.xaml.cs获取启动参数，根据不同的参数运行不同的xaml文件。
     如下：
     在.html页面或.aspx页面添加红色字体部分：
    <div id="silverlightControlHost">
        <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
        <param name="source" value="ClientBin/Video.xap"/>
        <param name="onError" value="onSilverlightError" />
        <param name="background" value="white" />
        <param name="minRuntimeVersion" value="3.0.40818.0" />
        <param name="autoUpgrade" value="true" />
         <param name="initParams" value="StartParm=Grid" />
        <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0" style="text-decoration:none">
             <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="获取 Microsoft Silverlight" style="border-style:none"/>
        </a>
        </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>
    在App.xaml.cs文件里获取参数：
        private void Application_Startup(object sender, StartupEventArgs e)
        {
            string start = " StartParm";　//对应.html页面或.aspx页面的参数里，value对应表达式的左边StartParm
            if (!e.InitParams.ContainsKey(start))//如果找不到对应的参数，则返回一个默认启动项
                this.RootVisual = new MainPage();
            else
            {
                switch (e.InitParams[start]) //根据参数不同启动不同xaml
                {
                    case "Ellipse":
                        this.RootVisual = new GridExam();
                        break;
                    case "Grid": //此例中传进的StartParm=Grid，因此将启动名称为SilverlightControl1的xaml文件
                        this.RootVisual = new SilverlightControl1();
                        break;
                    case "Rect":
                        this.RootVisual = new RectExam();
                        break;
                    case "Full":
                        this.RootVisual = new Fullscreen();
                        break;
                    default:
                        this.RootVisual = new MainPage();
                        break;
                }
            }

}
