问题 I hope my title is clear.... What I mean is for exmaple when we define animation: Xaml: <StoryBoard> <DoubleAnimation..../> </StoryBoard> But if we defines same thing in code-behind, we could do: DoubleAnimation myDAnimation = new DoubleAnimation(); ..... StoryBoard myStoryBoard = new StoryBoard(); myStoryBoard.Children.Add(myDAnimation); I tried to look into StoryBoard's class definition, nothing special: public sealed class Storyboard : Timeline { public Storyboard(); // Summary: // Gets

问题 What I want to do is define all the BeginTimes of my Animation using a resource. For example, I want: <sys:TimeSpan x:key="SomeResource">... </sys:TimeSpan> ... <DoubleAnimation BeginTime={StaticResource SomeResource}/> Obviously sys:TimeSpan is not the correct type to use.
