在MouseDoubleClick事件中从ListView打开文件

我正在尝试创建一个Windows资源管理器。我成功地填充treeView和listView像Windows资源管理器，但我有问题打开文件双击从列表视图。在MouseDoubleClick事件中从ListView打开文件

这是我到目前为止有：

try 
     { 
      //clears the collection so the listview has only the files of the folder thats clicked on 
      _fileDetails.Clear(); 


      DirectoryInfo dirInfo = new DirectoryInfo(SelectedImagePath); 
      FileInfo[] info = dirInfo.GetFiles(); 

      foreach (FileInfo fileInfo in info) 
      { 
       //adds files to the collection with its properties 
       _fileDetails.Add(new Details 
       { 
        FileName = fileInfo.Name, 
        Size = fileInfo.Length.ToString(), 
        DateCreated = fileInfo.CreationTime.ToString(), 
        DateModified = fileInfo.LastWriteTime.ToString(), 
        RevNumber = "?", 
        User = "?" 
       }); 

      } 
     }

其中fileDetails是我的ObservableCollection。

鼠标事件：

protected void HandleDoubleClick(object sender, MouseButtonEventArgs e) 
    { 
     DependencyObject src = (DependencyObject)(e.OriginalSource); 
     while (!(src is Control)) 
      src = VisualTreeHelper.GetParent(src); 
     MessageBox.Show("*** Double clicked on a " + src.GetType().FullName +"********************" + sender.ToString()); 
    }

的结合：

<ListView Height="335" HorizontalAlignment="Right" Margin="0,12,12,0" Name="fileExplorerView" VerticalAlignment="Top" Width="509" Grid.Column="1" ItemsSource="{Binding ElementName=This, Path=fileDetails}"> 
     <ListView.ItemContainerStyle> 
      <Style TargetType="{x:Type ListViewItem}"> 
       <EventSetter Event="MouseDoubleClick" Handler="HandleDoubleClick"/> 
      </Style> 
     </ListView.ItemContainerStyle> 
     <ListView.View> 

      <GridView> 
       <GridViewColumn Header="Name" Width="100" DisplayMemberBinding="{Binding FileName}"/> 
       <GridViewColumn Header="Size" Width="100" DisplayMemberBinding="{Binding Size}"/> 
       <GridViewColumn Header="Date Created" Width="100" DisplayMemberBinding="{Binding DateCreated}"/> 
       <GridViewColumn Header="Time Created" Width="100" DisplayMemberBinding="{Binding DateModified}"/> 
       <GridViewColumn Header="Revision Number" Width="100" DisplayMemberBinding="{Binding RevNumber}"/> 
       <GridViewColumn Header="Modified By" Width="100" DisplayMemberBinding="{Binding User}"/> 

      </GridView> 

     </ListView.View> 
    </ListView>

代替在鼠标事件在MessageBox的，我将使用一个过程来打开files.The问题是，我不能似乎弄清楚如何获得所选文件的路径。

谢谢

所有帮助将不胜感激。

喜欢的东西

var item = (FrameworkElement)sender; 
var file = (Details)item.DataContext; 
var path = file.Path; // Your Details class should save the FileInfo.FullName!

（为什么你有一个Details类呢？我只想用FileInfo对象）
