WPF ListView中的DateTime区域特定格式

Question

在WPF应用程序中,我有一个ListView:

<ListView Height="100" Width="434" Margin="0,2,0,0" x:Name="lvItems" ItemsSource="{Binding ElementName=MainWindow, Path=ShowQuCollection}" >
  <ListView.View>
    <GridView>
     <GridViewColumn Header="Date" Width="100" DisplayMemberBinding="{Binding Date}"/>
     <GridViewColumn Header="Time" Width="100" DisplayMemberBinding="{Binding Time}"/>
     <GridViewColumn Header="Description" Width="200" DisplayMemberBinding="{Binding Description}"/>
    </GridView>
   </ListView.View>
 </ListView>

通过数据绑定与ObservableCollection连接.使用LINQ to SQL从SQLServer db表填充ObservableCollection.

ObservableCollection<ShowsQu> _ShowQuCollection =
        new ObservableCollection<ShowsQu>();

public ObservableCollection<ShowsQu> ShowQuCollection
{ get { return _ShowQuCollection; } }

public class ShowsQu
{
    public string ShowCode { get; set; }
    public DateTime Date { get; set; }
    public TimeSpan Time { get; set; }
    public string Description { get; set; }
}

private void VisualizeAllShows()
{

    MyfirstdbDataContext context = new MyfirstdbDataContext();
    _ShowQuCollection.Clear();

    var sh = from p in context.Shows select p;

    foreach (var p in sh)  
      _ShowCollection.Add(new ShowsQu
        {
            Date = p.Date,
            Time = p.Time,
            Description = p.Description
        });                 
}

问题是ListView按原样显示SQLServer数据库表中的Date字段 - 没有应用特定于区域的格式(我猜测它应该默认应用).

我应该在哪里以及如何将其格式化为PC区域设置的方式？

出于某种原因,WPF不会自动获取当前的文化,您必须自己设置它.一种简单的方法是在应用程序启动事件中添加以下代码:

using System.Windows;
using System.Windows.Markup;
using System.Globalization;

...

void App_Startup(object sender, StartupEventArgs e)
{

    FrameworkElement.LanguageProperty.OverrideMetadata(  
        typeof(FrameworkElement),  
        new FrameworkPropertyMetadata(XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));
}
