How to instantiate PropertyPath for the StoryBoard with the Dependency property in C#?

Hi All

Below is the Xaml Code which is working as per the need to animate an image. I am tring to animate the same image through C#. Can Someone help in Setting the Storyboard.TargetProperty in C#.

How to instantiate PropertyPath for the StoryBoard with the Dependency property for Image Translate.XProperty in C# as shown below eg. (UIElement.RenderTransform).(TransformGroup.Children)[0].(TranslateTransform.X) which is in XAML.
