Itemssource是您正在进行的收藏。

Itemssource is the collection you're feeding in.

应绑定到List< DateTime>或ObservableCollection< DateTime>

That should be bound to a List<DateTime> or ObservableCollection<DateTime>

您可以通过模板化来设置项目的格式。

You can format the items by templating them.

这是一个完整的工作示例。

Here's a complete working example.

        Title="MainWindow" Height="350" Width="525"
        >
    <Window.DataContext>
        <local:MainWindowViewModel/>
    </Window.DataContext>
    <Grid>
        <ListBox ItemsSource="{Binding CollectionOfDates}"
                 SelectedItem="{Binding SelectedDate}"
         >
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding ., StringFormat={}{0:dd MMMM yy}}" />
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>
</Window>

和一个viewmodel

and a viewmodel

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.Runtime.CompilerServices;

namespace wpf_99
{
    public class MainWindowViewModel : INotifyPropertyChanged
    {
        private ObservableCollection<DateTime> collectionOfDates 
            = new ObservableCollection<DateTime>();

        public ObservableCollection<DateTime> CollectionOfDates
        {
            get { return collectionOfDates; }
            set { collectionOfDates = value; RaisePropertyChanged(); }
        }

        private DateTime selectedDate;

        public DateTime SelectedDate
        {
            get { return selectedDate; }
            set { selectedDate = value; RaisePropertyChanged();
                Console.WriteLine(

" Date Chosen：{value}"）;
}
}

公共事件PropertyChangedEventHandler PropertyChanged;

private void RaisePropertyChanged（[CallerMemberName] String propertyName =""）
{
PropertyChanged？.Invoke（this，new PropertyChangedEventArgs（propertyName））;
}

public MainWindowViewModel（）
{
CollectionOfDates = new ObservableCollection< DateTime>
（new List< DateTime> {DateTime.Now，DateTime.Now.Subtract（TimeSpan.FromDays（1））}）;
}
}
}

"Date Chosen: {value}"); } } public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged([CallerMemberName] String propertyName = "") { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } public MainWindowViewModel() { CollectionOfDates = new ObservableCollection<DateTime> (new List<DateTime> { DateTime.Now, DateTime.Now.Subtract(TimeSpan.FromDays(1)) }); } } }
