          {
 
              this.RootVisual = new MainPage();
 
              return;
 
          }
 
 
 
          Assembly assembly = Assembly.GetExecutingAssembly();
 
          String rootName = String.Format("Binglang.SilverlightDemo19.{0}", e.InitParams["InitPage"]);
 
          UIElement rootVisual = assembly.CreateInstance(rootName) as UIElement;
 
          this.RootVisual = rootVisual;
 
 
 
      }

 以上反射取得所需控件，也可以用下面反射代码：

 

 

?

String rootName = String.Format("Binglang.SilverlightDemo19.{0}", e.InitParams["InitPage"]);

 

?

Type type = Type.GetType(rootName );
  UIElement rootVisual = Activator.CreateInstance(type)  as UIElement;
 
 this.RootVisual  = (UIElement)this._contentPage;

                </a>
 
           </object><iframe id="_sl_historyFrame" style='visibility:hidden;height:0;width:0;border:0px'></iframe></div>

 2.调用不同SilverLight项目中的指定控件 

 

2.1.建立项目

(1)Binglang.SilverlightDemo20

(2)Binglang.SilverlightDemo20.Web

(3) Binglang.ExternalProject

 

注意：项目Binglang.SilverlightDemo20中需要引用using System.Xml.Linq;

 

假设(1)和(3)中各有一个控件，名称都为MainPage.xaml (不一定要相同)
