silverlight中实现页面传值


   
   该实例中使用独立存储的IsolatedStorageSettings 对象进行页面之间的传值

    将文本框txtName的值由MainPage.xaml页面传到Main.xaml页面。

   (1)使用该对象前,要在cs页面调用命名空间:System.IO.IsolatedStorage
   (2)MainPage.xaml:
     //定义独立的存储对象
        private IsolatedStorageSettings appSetting = IsolatedStorageSettings.ApplicationSettings;
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (txtName.Text != null && txtPwd.Text != null)
            {
                if (txtName.Text == "rainie" && txtPwd.Text == "123")
                {
                    //页面传值
                    if (!appSetting.Contains("name"))
                    {
                        appSetting.Add("name", txtName.Text.Trim());
                    }
              else
              {
               appSetting.Clear();
               appSetting.Add("name",txtName.Text.Trim());
            }

                    App.Navigation(new Main());
                }
            }
        }

    (3)Main.xaml接收值:
     //申明变量
        private IsolatedStorageSettings appSetting = IsolatedStorageSettings.ApplicationSettings;
        private void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
        {
            if (appSetting.Contains("name"))
            {
                tbName.Text = appSetting["name"].ToString();
            }
        }

    
    这样就实现了silverlight的页面传值功能。
