我无法让我的绑定工作在Detail ListView上.我已粘贴下面的所有MVVM模式代码.请帮忙!!!

我的观点:DirectoryDe​​tailView.cs

<UserControl x:Class="S2.Views.DirectoryDetailView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <ListView Grid.Column="0" ItemsSource="{Binding Path = DirectoryDetails}"
              IsSynchronizedWithCurrentItem="True"
              SelectedItem="{Binding SelectedDirName, Mode=TwoWay}">
        <ListView.View>
            <GridView>
                <GridViewColumn DisplayMemberBinding="{Binding Path = FileName}"
                                Header="File Name"/>
            </GridView>
        </ListView.View>
    </ListView>
    <ListView Grid.Column="1" Margin="10,0,0,0" ItemsSource="{Binding Path = DirectoryDetails}">
        <ListView.View>
            <GridView>
                <GridViewColumn DisplayMemberBinding="{Binding Path = FileDetails.Length}"
                                Header="Length"/>
                <GridViewColumn DisplayMemberBinding="{Binding Path = FileDetails.LastAccessTime}"
                                Header="LastAccessTime"/>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>

我的型号:

public class DirectoryModel : INotifyPropertyChanged
{
    private string _fileName;
    private DateTime _createdTime;

    public string FileName
    {
        get
        {
            return _fileName; …
