Silverlight之Frame傳遞多個引數並獲取完整引數

          

    if (strXapOrXaml == "xaml")
                {
                    string[] s = { "ClientBin" };
                    //這裡控制是相對地址還是絕對地址
                    string url = "";
                    if (menuUrl.StartsWith("http://"))
                    {
                        url = menuUrl.ToString().Trim();
                    }
                    else
                    {
                        url = App.Current.Host.Source.OriginalString.ToString().Split(s, StringSplitOptions.RemoveEmptyEntries)[0] + menuUrl.ToString().Trim(new char[] { '.', '/' });
                    }
                    cpt.frmMain.Navigate(new Uri("/AspxContainer.xaml?tourl=" + url, UriKind.Relative)); 
                    tchA.imgRefresh.Tag = url; //獲取頁面URL地址並賦值 2013-01-30
                }

 

這裡比如url中帶多個引數：

./YSQ/page2.aspx?stype=2&sdefault=0

 

<navigation:Page x:Class="WebMain.AspxContainer"

        protected override void OnNavigatedTo(NavigationEventArgs e)
        {

            if (this.NavigationContext.QueryString.ContainsKey("tourl"))
            { 
                //載入頁面
                string url = e.Uri.ToString().Substring(26); //去掉前面的字串/AspxContainer.xaml?tourl=
                this.htmlPlaceholderHost1.SourceUri = new Uri(url, UriKind.RelativeOrAbsolute);
            }

        {
            base.OnNavigatedFrom(e);

    }
}

 

 

在重構函式OnNavigatedTo函式中使用引數e的Uri屬性，是解決這個問題的關鍵！
