asp.net ajax调用后台方法 -- asp.net传值到silverlight

ajax调用asp.net后台方法：

test.aspx.cs后台代码如下：

 [WebMethod]
        public static string test1()
        {
            return "hello";
        }
//特别要提醒的是此处返回的值是{"d":""}格式，也就是说返回的值是{"d":"hello"}

test.aspx ajax代码

 $.ajax({
            type: "Post",
            url: "deepzooming.aspx/imgsall",
            contentType: "application/json; charset=utf-8",
            success: function (ms) {
                                alert("msg" + ms.d);
                
            }
        });

asp.net传值到silverlight：

显示silverlight控件的html代码：

在app.xaml.cs注册TrendMethod的代码：

private void Application_Startup(object sender, StartupEventArgs e)
        {
            this.RootVisual = new MainPage();
            System.Windows.Browser.HtmlPage.RegisterScriptableObject("TrendMethod", this.RootVisual);
        }

在Mainpage.xaml.cs中添加要调用的方法代码如下：

[ScriptableMember]
        public void GetThree(string imgfile)
        {
            msi.Source = new DeepZoomImageTileSource(new System.Uri("/"+imgfile+"/dzc_output.xml", UriKind.Relative));
            // LayoutRoot.Children.Add(msi);
            msi.UpdateLayout();
        }
