Xceed.Wpf.Toolkit.PropertyGrid.PropertyGrid：本地創建的對象屬於其他線程嗎？

Question

看看它，沒有任何意義：

對象是在本地創建的，沒有外部依賴關系。 怎么可能？

（此處創建的類型是Xceed.Wpf.Toolkit.PropertyGrid.PropertyGrid ）

這是堆棧跟蹤：

如果使用UI線程的分派器執行了一些初始化，則您應該可以使用以下代碼：

System.Windows.Application.Current.Dispatcher.Invoke(
    System.Windows.Threading.DispatcherPriority.Normal,
    (System.Action)delegate()
    {
         tempPropertyGrid.SelectedObject = new object();
    });

我不確定這是否可以解決您的問題，但是值得一試。
