<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">

<TextBox Height="72" HorizontalAlignment="Left" Name="param2TextBox" Text="" VerticalAlignment="Top" Width="440" MaxLength="63"/>
</StackPanel>
</ScrollViewer>
</Grid>
和 C#:
private void ApplicationBarSaveButton_Click(object sender, EventArgs e)
{
String name = System.Guid.NewGuid().ToString();
DateTime date = (DateTime)beginDatePicker.Value;
DateTime time = (DateTime)beginTimePicker.Value;
DateTime beginTime = date + time.TimeOfDay;
if (beginTime < DateTime.Now)
{
MessageBox.Show("the begin date must be in the future.");
return;
}
date = (DateTime)expirationDatePicker.Value;
time = (DateTime)expirationTimePicker.Value;
DateTime expirationTime = date + time.TimeOfDay;
if (expirationTime < beginTime)
{
MessageBox.Show("expiration time must be after the begin time.");
return;
}
RecurrenceInterval recurrence = RecurrenceInterval.None;
if (dailyRadioButton.IsChecked == true)
{
recurrence = RecurrenceInterval.Daily;
}
else if (weeklyRadioButton.IsChecked == true)
{
recurrence = RecurrenceInterval.Weekly;
}
else if (monthlyRadioButton.IsChecked == true)
{
recurrence = RecurrenceInterval.Monthly;
}
else if (endOfMonthRadioButton.IsChecked == true)
{
recurrence = RecurrenceInterval.EndOfMonth;
}
else if (yearlyRadioButton.IsChecked == true)
{
recurrence = RecurrenceInterval.Yearly;
}
string param1Value = param1TextBox.Text;
string param2Value = param2TextBox.Text;
string queryString = "";
if (param1Value != "" && param2Value != "")
{
queryString = "?param1=" + param1Value + "¶m2=" + param2Value;
}
else if (param1Value != "" || param2Value != "")
{
queryString = (param1Value != null) ? "?param1=" + param1Value : "?param2=" + param2Value;
}
Uri navigationUri = new Uri("/ShowParams.xaml" + queryString, UriKind.Relative);
if ((bool)reminderRadioButton.IsChecked)
{
Reminder reminder = new Reminder(name);
reminder.Title = titleTextBox.Text;
reminder.Content = contentTextBox.Text;
reminder.BeginTime = beginTime;
reminder.ExpirationTime = expirationTime;
reminder.RecurrenceType = recurrence;
reminder.NavigationUri = navigationUri;
// Register the reminder with the system.
ScheduledActionService.Add(reminder);
}
else
{
Alarm alarm = new Alarm(name);
alarm.Content = contentTextBox.Text;
alarm.Sound = new Uri("/Ringtones/Ring01.wma", UriKind.Relative);
alarm.BeginTime = beginTime;
alarm.ExpirationTime = expirationTime;
alarm.RecurrenceType = recurrence;
ScheduledActionService.Add(alarm);
}
// Navigate back to the main reminder list page.
NavigationService.GoBack();
}
推荐答案
我复制了你的代码，没有任何改变，除了这一行之外，它可以完美运行:
I copied your code changed nothing and it would work perfectly except for this line:
alarm.Sound = new Uri("/Ringtones/Ring01.wma", UriKind.Relative);
如果未删除该行(或将文件添加到手机中)，则每次添加警报时都会崩溃
which makes it crash EVERYTIME on adding the alarm if that line is not removed (or the file is added to the phone)
只需将其注释掉，您的代码就可以运行了.
Just comment it out and your code should work.
