日期时间减去uwp

我想用时间减去两个日期。最后，我会得到像44天，14小时，15分钟的东西。现在我只得到时间2时03分00秒（秒我不需求。）日期时间减去uwp

的日期和时间，我从日期选择器和时间选择器将士

XAML代码

 <StackPanel HorizontalAlignment="Left"> 
      <!--<TextBlock x:Name="textblock" Text="textblock"/>--> 

      <DatePicker x:Name="datepicker1" Margin="10"/> 
      <TimePicker x:Name="timepicker1" Margin="10"/> 
      <DatePicker x:Name="datepicker2" Margin="10"/> 
      <TimePicker x:Name="timepicker2" Margin="10"/> 
      <Button x:Name="datumbutton" Click="datumbutton_Click" Content="Combine"/> 
      <TextBlock x:Name="datumtextblock" Margin="20" Text="datum" /> 
      <TextBlock x:Name="datumtextblock2" Text="datum2"/> 
      <TextBlock x:Name="vysledek" Text="vysledek"/> 
     </StackPanel>

UWP代码

using Windows.Globalization; 
using Windows.Globalization.DateTimeFormatting;   

private void datumbutton_Click(object sender, RoutedEventArgs e) 
      { 
       DateTimeFormatter dateFormatter = new DateTimeFormatter("shortdate"); 
       DateTimeFormatter timeFormatter = new DateTimeFormatter("shorttime"); 

       Calendar calendar = new Calendar(); 
       calendar.ChangeClock("24HourClock"); 

       DateTimeOffset selectedDate = this.datepicker1.Date; 
       DateTimeOffset combinedValue = new DateTimeOffset(new DateTime(selectedDate.Year, selectedDate.Month, selectedDate.Day) + this.timepicker1.Time); 

       DateTimeOffset selectedDate2 = this.datepicker2.Date; 
       DateTimeOffset combinedValue2 = new DateTimeOffset(new DateTime(selectedDate.Year, selectedDate.Month, selectedDate.Day) + this.timepicker2.Time); 

       calendar.SetDateTime(combinedValue); 
       calendar.SetDateTime(combinedValue2); 


       datumtextblock.Text= ("Combined value: " + dateFormatter.Format(combinedValue) + " " + timeFormatter.Format(combinedValue)); 
       datumtextblock2.Text = ("Combined value: " + dateFormatter.Format(combinedValue2) + " " + timeFormatter.Format(combinedValue2)); 
       System.TimeSpan odecet = combinedValue.Subtract(combinedValue2); 
       vysledek.Text = odecet.ToString(); 

      }

代码中存在轻微的疏忽。当越来越combinedValue2，你应该使用的

DateTimeOffset combinedValue2 = new DateTimeOffset(new DateTime(selectedDate2.Year, selectedDate2.Month, selectedDate2.Day) + this.timepicker2.Time);

代替

DateTimeOffset combinedValue2 = new DateTimeOffset(new DateTime(selectedDate.Year, selectedDate.Month, selectedDate.Day) + this.timepicker2.Time);

在此之后，你可以使用类似下面来得到你想要的。

vysledek.Text = $"{odecet.Days} days, {odecet.Hours} hours, {odecet.Minutes} minutes";

如果你想总是得到绝对值，你可以使用TimeSpan.Duration Method像var absoluteOdecet = odecet.Duration();。
