WPF:在网格视图模式下将列表视图与集合绑定.错误

因此，我正在尝试将 GridView 模式下的 ListView 与我的集合绑定。以下是 XAML：

<Window x:Class="MyApp.ParametersWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Height="340" Width="300"
    DataContext="{Binding RelativeSource={RelativeSource Self}}">
<Grid>
    <Button Content="Cancel" Height="23" HorizontalAlignment="Left" Margin="39,254,0,0" Name="button1" VerticalAlignment="Top" Width="75" />
    <Button Content="Run Test" Height="23" HorizontalAlignment="Right" Margin="0,254,51,0" Name="button2" VerticalAlignment="Top" Width="75" Click="button2_Click" />
    <ListView Height="227" HorizontalAlignment="Left" Margin="21,12,0,0" Name="listView1" VerticalAlignment="Top" Width="237"  ItemsSource="{Binding FileNames}">
        <GridView>
            <GridViewColumn Width="120" Header="Vorname" DisplayMemberBinding="{Binding Name}" />    **<!--Error in this line-->**            
        </GridView>
    </ListView>
</Grid>

以下是*.cs：

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Windows;
namespace AtmlServiceClient
{
    public partial class ParametersWindow : Window
    {
    public class FileInfo
    {
        public string Name { get; set; }
        public DateTime LastModified { get; set; }
    }
    ObservableCollection<FileInfo> mFileNames;
    public ObservableCollection<FileInfo> FileNames
    {
        get
        {
            return mFileNames;
        }
    }
    public ParametersWindow()
    {
        mFileNames = new ObservableCollection<FileInfo>();
        InitializeComponent();            
    }
    private void button2_Click(object sender, RoutedEventArgs e)
    {
        FileNames.Add(new FileInfo() {Name = "X", LastModified = DateTime.Now});
    }
}
}

窗口出现时，我收到了下一个错误。（点击按钮时不行）

错误：

在

PresentationFramework 中发生了类型为"System.Windows.Markup.XamlParseException"的第一次机会异常.dll 附加信息："向类型为'System.Windows.Controls.ItemCollection'类型的集合添加值引发异常。行号"11"和行位置"62"。

请帮我解决它。
