windows phone不同页面间传值

在windows phone中，不同页面间传值是用以下代码就可以了

PhoneApplicationService.Current.State[“strKey”]

我自己封装的代码：

TripDealer.cs:

using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.Phone.Shell;

namespace lifeCircle.Classes {     public class TripDealer     {         private const string tripKey = "trip";

        public TripInfo CurrentTrip         {             get             {                 if (!PhoneApplicationService.Current.State.ContainsKey(tripKey))                 {                     return null;                 }                 else                 {                     return PhoneApplicationService.Current.State[tripKey] as TripInfo;                 }             }             set { PhoneApplicationService.Current.State[tripKey] = value; }         }             } }

consuming Code:

using lifeCircle.Classes;

TripDealer objDealer = new TripDealer();

if (null == objDealer.CurrentTrip)             {                 tbDate.Text = DateTime.Now.ToString("yyyy-MM-dd");             }

 

if (null == objDealer.CurrentTrip)             {                 objDealer.CurrentTrip = new TripInfo();             }             objDealer.CurrentTrip.Name = tbTripName.Text;             objDealer.CurrentTrip.TripDate = DateTime.Parse(tbDate.Text);             objDealer.CurrentTrip.MemberList = tbMembers.Text;             NavigationService.Navigate(new Uri("/Pages/TripEditSecond.xaml",UriKind.Relative));
