silverlight 可以通过属性InitParams 获得参数，如果参数是动态的需要web程序传递的，具体操作如下：
web程序后台：
this.frmReport.Attributes["src"] = String.Format("../../SilverlightApplicationTestPage.aspx?AppID={0}&USERID={1}", AppID, this.CurrentUserInfo.CurrUserInfo.USERID.ToString());
silverlight项目会生产一个 测试页面文件：SilverlightApplicationTestPage.aspx，代码如下：
<%@ Page Language="c#" AutoEventWireup="true" %>

function onSilverlightError(sender, args)

var errorType =
args.ErrorType;
var iErrorCode = args.ErrorCode;
if (errorType ==

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

throw new

}
//加载参数
function WindOnLoad()
{
var xmlDoc;
var initParamsString = ‘‘;
var url = location.href;
var paraString = url.substring(url.indexOf("?") + 1,
url.length).split("&");
for (var i = 0; i < paraString.length; i++) {
initParamsString += paraString[i];
if (i != paraString.length) {
initParamsString += ",";
}
}
SetInitParams(initParamsString);
}
//构造页面
function
SetInitParams(initParamsString)
{
var
silverlightControlHtml = ‘ <object id="silverlightControl"

}
window.onload = WindOnLoad;

silverlight程序会生成app.xaml 文件作为起始页面，代码如下：
public App()
{
this.Startup +=
this.Application_Startup;
this.UnhandledException += this.Application_UnhandledException;
InitializeComponent();
}
//在Application_Startup方法中得到web程序的参数，具体代码如下：
private void Application_Startup(object sender, StartupEventArgs
e)
{
paras = e.InitParams;
AppID = e.InitParams["AppID"];
USERID =
e.InitParams["USERID"];
this.RootVisual = new BeginHome(AppID,
USERID);//跳转到其他页面
}
