silverlight 用户浏览器未安装SL插件问题

1.在Silverlight启动页面

 <%@ Page Language="C#" AutoEventWireup="true" %>

 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

 <html xmlns="http://www.w3.org/1999/xhtml">

 <head runat="server">

     <title>SilverlightApplication9</title>

     <style type="text/css">

         html, body {

             height: %;

             overflow: auto;

         }

         body {

             padding: ;

             margin: ;

         }

         #silverlightControlHost {

             height: %;

             text-align: center;

         }

     </style>

     <script type="text/javascript" src="SplashScreen.js"></script>

     <script type="text/javascript" src="Silverlight.js"></script>

     <script type="text/javascript">

         function onSilverlightError(sender, args) {

             var appSource = "";

             if (sender != null && sender != ) {

                 appSource = sender.getHost().Source;

             }

             var errorType = args.ErrorType;

             var iErrorCode = args.ErrorCode;

             if (errorType == "ImageError" || errorType == "MediaError") {

                 return;

             }

             var errMsg = "Silverlight 应用程序中未处理的错误 " + appSource + "\n";

             errMsg += "代码: " + iErrorCode + "    \n";

             errMsg += "类别: " + errorType + "       \n";

             errMsg += "消息: " + args.ErrorMessage + "     \n";

             if (errorType == "ParserError") {

                 errMsg += "文件: " + args.xamlFile + "     \n";

                 errMsg += "行: " + args.lineNumber + "     \n";

                 errMsg += "位置: " + args.charPosition + "     \n";

             }

             else if (errorType == "RuntimeError") {

                 if (args.lineNumber != ) {

                     errMsg += "行: " + args.lineNumber + "     \n";

                     errMsg += "位置: " + args.charPosition + "     \n";

                 }

                 errMsg += "方法名称: " + args.methodName + "     \n";

             }

             throw new Error(errMsg);

         }

     </script>

 </head>

 <body>

     <form id="form1" runat="server" style="height: 100%">

         <div id="silverlightControlHost">

             <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

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

         </div>

     </form>

 </body>

 </html>

2.在Silverlight.web服务端添加要显示的图片及路径、silverlight插件的两个版本（32位、64位）

3.在silverlight.web服务端添加DownloadSilverlight.aspx项

 using System;

 using System.Linq;

 using System.Web.UI;

 using System.Web.UI.WebControls;

 namespace SilverlightApplication9.Web

 {

     public partial class DownloadSilverlight : System.Web.UI.Page

     {

         protected void Page_Load(object sender, EventArgs e)

         {

             //string info = "客户端IP：" + Page.Request.UserHostAddress;

             //// Load ServerVariable collection into NameValueCollection object.

             //coll = Request.ServerVariables;

             //// Get names of all keys into a string array.

             //String[] arr1 = coll.AllKeys;

             //for (loop1 = 0; loop1 < arr1.Length; loop1++)

             //{

             //    Response.Write("Key: " + arr1[loop1] + "<br>");

             //    String[] arr2 = coll.GetValues(arr1[loop1]);

             //    for (loop2 = 0; loop2 < arr2.Length; loop2++)

             //    {

             //        Response.Write("Value " + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>");

             //    }

             //}

             //Response.End();

             if (Request.ServerVariables["HTTP_USER_AGENT"].ToString().Contains("WOW64"))

             {

                 Response.Redirect("/Silverlight/Silverlight_x64.exe");

             }

             else

             {

                 Response.Redirect("/Silverlight/Silverlight.exe");

             }

         }

     }

 }
