FindName和FindLogicalNode返回null

Question

我在运行时programmaticaly添加了一个元素：

private void AddModule(string modulename, string ip, string description)
    {
        ModuleInfobox infobox = new ModuleInfobox();
        infobox.Modulename = modulename;
        infobox.IpAddress = ip;
        infobox.Description = description;
        infobox.Modulenamecolor = "Lime";
        infobox.Name = modulename;
        ModulePanel.RegisterName(infobox.Name, infobox);
        ModulePanel.Children.Add(infobox);
    }

ModuleInfoBox是我的UserControl。现在我需要对这个对象的引用。我试试这个：

private FindLogicalNodeDelegate delFindLogicalNode;
private FindNameDelegate delFindName;
delegate object FindLogicalNodeDelegate(DependencyObject wantedObject, string name);
delegate object FindNameDelegate(string name);
delFindLogicalNode = new FindLogicalNodeDelegate(LogicalTreeHelper.FindLogicalNode);
delFindName = new FindNameDelegate(ModulePanel.FindName);

在一个帖子中：

object wantedObject = ModulePanel.Dispatcher.BeginInvoke(delFindLogicalNode, DispatcherPriority.Normal, ModulePanel, "modulename").Result;
object wantedObject2 =  this.Dispatcher.BeginInvoke(delFindName, DispatcherPriority.Normal, "moduleName").Result;

当我使用调试器时，FindLogicalNode有时会找到引用，但通常不会。 我阅读了以下主题：WPF - FindName Returns null when it should not和"FindName" doesn't work if an element added in code 但我的代码中仍然存在错误
