Silverlight传递初始化时的参数

 

1.第一种方式

 

 //第一种方式
            foreach (var item in HtmlPage.Document.QueryString)
            {
                TextBlock tb = new TextBlock();
                tb.Text = string.Format("{0}:{1}", item.Key, item.Value);
                InitParams.Children.Add(tb);
            }

2.第二.三种方式前台

 <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>
     <asp:Silverlight ID="Silverlight1" runat="server" Source ="~/ClientBin/InitParams.xap"
       InitParameters ="name=hahacjh" Height="100px" Width="100px">
    </asp:Silverlight>
    </div>
<!-----------------------------------------或---------------------------------------->
<object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" width="100%" height="100%">
            <param name="source" value="ClientBin/InitParams_CS.xap"/>
            <param name="onerror" value="onSilverlightError" />
            <param name="background" value="white" />
            <param name="initParams" value="name=tim,lastname=heuer" />
            <a href="http://go.microsoft.com/fwlink/?LinkID=115261" style="text-decoration: none;">
                 <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
            </a>
        </object>

 

 

第二种方式后台：

App.xaml.cs
  private void Application_Startup(object sender, StartupEventArgs e)
        {
            if (e.InitParams != null)
            {
                foreach (var item in e.InitParams)
                {
                    this.Resources.Add(item.Key, item.Value);
                }
            }
            this.RootVisual = new Page();
        }
Page.xaml.cs
void Page_Loaded(object sender, RoutedEventArgs e)
        {
            if (App.Current.Resources.Contains("name"))
            {
                string  fname = App.Current.Resources["name"].ToString();
                TextBlock tb = new TextBlock();
                tb.Text = fname;
                InitParams.Children.Add(tb);
            }
        }

第三种方式

App.xaml.cs
  private void Application_Startup(object sender, StartupEventArgs e)
  {
            string name = string.Empty;
            if (e.InitParams.Keys.Contains("name"))
            {
                name = e.InitParams["name"].ToString();
            }
            this.RootVisual = new Page(name);
  }
Page.xaml.cs
 public partial class Page : UserControl
    {
        string firtName = string.Empty;
        public Page(string name)
        {
            InitializeComponent();
            Loaded += new RoutedEventHandler(Page_Loaded);
            this.Name = name;
        }
        void Page_Loaded(object sender, RoutedEventArgs e)
        {
            TextBlock tb = new TextBlock();
            tb.Text = this.Name;
            InitParams.Children.Add(tb);
        }
    }
