WPF动画警告：6：无法执行操作 [英] WPF Animation Warning: 6 : Unable to perform action

问题描述

我在VIsual Studio输出面板中的WPF应用程序中观察到以下警告：

I observe in my WPF application warning in VIsual Studio Output panel with following text:

WPF动画警告：6：无法执行操作，因为指定的
情节提要板从未应用到此对象以进行交互式
控件。Action='Stop';
Storyboard = System.Windows.Media.Animation.Storyboard；
Storyboard.HashCode ='65981734'； Storyboard.Type = System.Windows.Media.Animation.Storyboard；
TargetElement ='System.Windows.Controls.ContentPresenter';
TargetElement.HashCode ='49882372';
TargetElement.Type ='System.Windows.Controls.ContentPresenter'

WPF Animation Warning: 6 : Unable to perform action because the specified Storyboard was never applied to this object for interactive control.Action='Stop'; Storyboard='System.Windows.Media.Animation.Storyboard'; Storyboard.HashCode='65981734'; Storyboard.Type='System.Windows.Media.Animation.Storyboard'; TargetElement='System.Windows.Controls.ContentPresenter'; TargetElement.HashCode='49882372'; TargetElement.Type='System.Windows.Controls.ContentPresenter'

如何将HashCode反转为某些xaml元件？如何查找该动画的附加位置？

How can I 'reverse' HashCode to some xaml element? How to find where that animation is attached?

预先感谢

推荐答案

您可以使用以下代码找到您的StoryBoard：

You can use the following code to find your StoryBoard:

private string GetStoryBoardNameByHashCode(int hashCode)
{
    foreach (DictionaryEntry resource in Resources)
    {
        if (resource.Value is Storyboard)
        {
            if (resource.GetHashCode() == hashCode)
                return ((Storyboard) resource.Value).Name;
        }
    }
    return String.Empty;
}

执行如下方法：

    string storyBoardName = GetStoryBoardNameByHashCode(65981734);

这应该能够使用HashCode获得StoryBoard-Name（如果您想获得指定的StoryBoard，您也可以将其返回）。请注意，此处的ResourceDictionary位于窗口范围内（本地）。因此，如果StoryBoards都位于应用程序的ResourceDictionary（App.xaml）中，则将 Resources更改为：

This should be able to get the StoryBoard-Name with the HashCode (ór if you want to get the specified StoryBoard, you can return that as well). Mind you that the ResourceDictionary is on Window-scope (local) here. So, if the StoryBoards are all located in the ResourceDictionary of the Application (App.xaml) then change 'Resources' to:

Application.Current.Resources

可能有另一种方法来获取WPF应用程序的所有资源而不只是本地或应用程序范围，但尚未对此进行研究。希望这段代码可以让您找到问题所在。

There may be an alternative way to get all the Resources of a WPF-application instead of just the local or Application-scope, but haven't looked into this. Hopefully, this code allows you to find your problem.

这里是示例代码，以防万一您需要它！

Here's the sample code, just in case you'd need it!
