我注意到代码中存在内存泄漏 我使用Ants内存分析器来查看内存泄漏的来源 我唯一要做的就是在我的应用程序中切换标签。
我已从WPF扩展工具包2.0.0.0升级 - > 2.5.0.0但这并没有解决我的问题
有一个collectionchangedeventhandler,它有7个实例
一切都在obserablecollection<BaseViewerTabItem>
这是我的代码的一部分:
public class ViewerBaseViewModel : ViewModelBase
{
protected bool IsViewerMode; // Used to identify if the image was loaded from a file to the viewer mode
protected ImageManager _imageManager;
private readonly IMessageBoxService _messageBoxService;
private readonly ProgressIndicatorViewModel _progressIndicator;
protected ImageCollection CurrentImageCollection { get; set; }
protected int _imageTabCounter = 1;
private Dictionary<int, List<ImageViewerTabItem>> _groupedImages;
public ObservableCollection<BaseViewerTabItem> OpenViewers { get; private set; }
ImageViewerTabItem类注册到OpenViewersCollectionChanged事件 如你所见,也可以从中取消注册
public ImageViewerTabItem(RelayCommand<ImageViewerTabItem> closeTabCommand, RelayCommand<ImageViewerTabItem> duplicateTabcommand, RelayCommand<AttachableItem> attachTabCommand,
RelayCommand<ImageViewerTabItem> detachTabCommand, RelayCommand ungroupAllCommand, RelayCommand groupAllCommand, ObservableCollection<BaseViewerTabItem> openViewers, Dictionary<int, List<ImageViewerTabItem>> groupedImages)
{
_closeTabCommand = closeTabCommand;
_duplicateTabcommand = duplicateTabcommand;
_attachTabCommand = attachTabCommand;
_detachTabCommand = detachTabCommand;
_ungroupAllCommand = ungroupAllCommand;
_groupAllCommand = groupAllCommand;
OpenViewers = openViewers;
_groupedImages = groupedImages;
OpenViewers.CollectionChanged += OpenViewersChanged;
}
public void TearDown()
{
OnTabClosed();
OpenViewers.CollectionChanged -= OpenViewersChanged;
ImageContentViewModel.TearDown();
}
这是我的Xaml代码
<Grid>
<xcad:DockingManager DocumentsSource="{Binding OpenViewers}"
x:Name="MainTabControl"
LayoutItemTemplate="{StaticResource imageSelectionTemplate}"
ActiveContent="{Binding ActiveTabItem, Mode=TwoWay}"
DocumentHeaderTemplate="{StaticResource DocumentHeaderDataTemplate}"
DocumentTitleTemplate="{StaticResource DocumentTitleDataTemplate}" IsHitTestVisible="True" VerticalContentAlignment="Stretch" VerticalAlignment="Stretch">
<xcad:LayoutRoot>
<xcad:LayoutPanel Orientation="Horizontal" >
<xcad:LayoutDocumentPane />
</xcad:LayoutPanel>
</xcad:LayoutRoot>
</xcad:DockingManager>
</Grid>
你能说出我的问题所在吗?
或者如何找到内存泄漏?
Avalon dock可以有内存泄漏吗?
