C# 如何将事件提醒添加到我的windows phone 7应用程序

我正在windows phone 7中构建一个应用程序，需要在其中添加事件提醒。单击按钮时，应设置提醒。我的cs文件是：

namespace KejriwalPhoneApp
{
public partial class EventDetails : PhoneApplicationPage
{

    public EventDetails()
    {
        InitializeComponent();

        ApplicationBar = new ApplicationBar();
        ApplicationBar.Mode = ApplicationBarMode.Default;
        ApplicationBar.Opacity = 1.0;
        ApplicationBar.IsVisible = true;


        ApplicationBarIconButton home = new ApplicationBarIconButton();
        home.IconUri = new Uri("/Image/icon_home_deselect.png", UriKind.Relative);
        home.Text = "Home";
        ApplicationBar.Buttons.Add(home);
        home.Click += new EventHandler(home_Click);


        ApplicationBarIconButton share = new ApplicationBarIconButton();
        share.IconUri = new Uri("/Image/icon_share_deselect.png", UriKind.Relative);
        share.Text = "Share";
        ApplicationBar.Buttons.Add(share);
        share.Click += new EventHandler(share_Click);

        ApplicationBarIconButton news = new ApplicationBarIconButton();
        news.IconUri = new Uri("Image/icon_news_deselect.png", UriKind.Relative);
        news.Text = "News";
        ApplicationBar.Buttons.Add(news);
        news.Click += new EventHandler(news_Click);

        ApplicationBarIconButton events = new ApplicationBarIconButton();
        events.IconUri = new Uri("/Image/icon_event_deselect.png", UriKind.Relative);
        events.Text = "Video";
        ApplicationBar.Buttons.Add(events);
        events.Click += new EventHandler(events_Click);
    }

    void events_Click(object sender, EventArgs e)
    {
        NavigationService.Navigate(new Uri("/Events.xaml", UriKind.Relative));
    }

    void news_Click(object sender, EventArgs e)
    {
        NavigationService.Navigate(new Uri("/News.xaml", UriKind.Relative));
    }

    void share_Click(object sender, EventArgs e)
    {
        NavigationService.Navigate(new Uri("/share.xaml", UriKind.Relative));

    }

    void home_Click(object sender, EventArgs e)
    {
        NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative));
    }

    private void Image_Back(object sender, RoutedEventArgs e)
    {
        NavigationService.Navigate(new Uri("/Events.xaml", UriKind.Relative));
    }

    protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
    {
        base.OnNavigatedTo(e);
        var imagePath = "";
        var eventdate = "";
        var location = "";
        var utimee = "";
        var tzone = "";
        var ename = "";
        var desc = "";

        //check if particular parameter available in uri string
        if (this.NavigationContext.QueryString.ContainsKey("image_path"))
        {
            //if it is available, get parameter value
            imagePath = NavigationContext.QueryString["image_path"];

            eventimage.Source = new BitmapImage(new Uri(@"http://political-leader.vzons.com/ArvindKejriwal/images/uploaded/" + imagePath, UriKind.Absolute));


        }

        if (this.NavigationContext.QueryString.ContainsKey("Time_Zone"))
        {
            tzone = NavigationContext.QueryString["Time_Zone"];
            timezone.Text = tzone;
        }

        if (this.NavigationContext.QueryString.ContainsKey("uTime"))
        {
            utimee = NavigationContext.QueryString["uTime"];
            utime.Text = utimee;
        }

        if (this.NavigationContext.QueryString.ContainsKey("Event_Date"))
        {
            //if it is available, get parameter value
            eventdate = NavigationContext.QueryString["Event_Date"];
            evntdate.Text = eventdate;
        }

        if (this.NavigationContext.QueryString.ContainsKey("Location"))
        {
            //if it is available, get parameter value
            location = NavigationContext.QueryString["Location"];
            loc.Text = location;
        }

        if (this.NavigationContext.QueryString.ContainsKey("Event_Name"))
        {
            //if it is available, get parameter value
            ename = NavigationContext.QueryString["Event_Name"];
            enamee.Text = ename;
        }
        if (this.NavigationContext.QueryString.ContainsKey("Event_Description"))
        {
            //if it is available, get parameter value
            desc = NavigationContext.QueryString["Event_Description"];
            edescription.Text = desc;
        }

}

}现在，当点击提醒按钮时，我希望设置utimee、tzone字段，并弹出消息“事件提醒添加成功”

我不知道如何做

您可以执行以下步骤：

1.从webservice获取作为全局变量的值：

事件日期、位置、utimee、tzone、ename、描述

2.点击提醒按钮，执行点击方式

private void BtnReminderClick(object sender, EventArgs e)
{
    RegisterReminder();
}

3.做提醒登记

    private void RegisterReminder()
    {
        var reminder = ScheduledActionService.Find(ename) as Reminder ?? new Reminder(ename);
        reminder.Title = ename;
        reminder.Content = desc;
// parse eventDate,utimee to beginDateTime
        reminder.BeginTime = DateTime.Parse(eventDate).Date + DateTime.Parse(utimee).TimeOfDay;
        reminder.ExpirationTime = reminder.BeginTime.AddDays(1);
        reminder.RecurrenceType = RecurrenceInterval.None;
        if (ScheduledActionService.Find(ename) == null)
           ScheduledActionService.Add(reminder);
        else
           ScheduledActionService.Replace(reminder);
       MessageBox.Show("reminder set succeed!");
    }

你试过什么了吗？你说的“我想设置utimee、tzone字段，然后我会弹出一个窗口”是什么意思？@ChrisShao点击提醒按钮时，会看到我从web服务获得的数据，即日期、时区和utime，这些数据应该在我的设备中设置，我应该会收到一条弹出消息，提示已设置。我能把事情说清楚吗？是的，你应该根据你的数据在提醒中设置标题、内容、开始时间、过期时间和重复发生类型，之后，你可以弹出一条消息。嗨，@user3156298，请阅读我的代码。我收到一些错误：ename、desc、begindatetime在当前上下文中不存在。我知道，你可以设置aname、desc eventDate，utimee作为全局变量。beginDateTime是一个DateTime类型的变量，可以从eventDate和utimee解析。我已经设置了这些全局变量，即ename、desc、eventDate和utimee。你能在你的代码中解析beginDateTime吗？它工作得很好。谢谢你能告诉我一件事吗。。。是否有办法在中央显示消息框？默认消息框位于屏幕顶部。这是wp的默认syle。

    private void RegisterReminder()
    {
        var reminder = ScheduledActionService.Find(ename) as Reminder ?? new Reminder(ename);
        reminder.Title = ename;
        reminder.Content = desc;
// parse eventDate,utimee to beginDateTime
        reminder.BeginTime = DateTime.Parse(eventDate).Date + DateTime.Parse(utimee).TimeOfDay;
        reminder.ExpirationTime = reminder.BeginTime.AddDays(1);
        reminder.RecurrenceType = RecurrenceInterval.None;
        if (ScheduledActionService.Find(ename) == null)
           ScheduledActionService.Add(reminder);
        else
           ScheduledActionService.Replace(reminder);
       MessageBox.Show("reminder set succeed!");
    }
