Represents a collection of GradientStop objects that can be individually accessed by index.
GradientStopCollection defines no methods or properties beyond the basic Collection methods and properties. Methods such as Add or GetItem will expect or return objects that are of type LinearGradientBrush or RadialGradientBrush.
The XAML syntax for properties that use a GradientStopCollection is an example of implicit collection syntax, in which you can omit an actual GradientStopCollection object element. Explicitly including a GradientStopCollection object element is permissible XAML syntax and might be useful if you intend to name the collection in XAML and manipulate its contents through script later.
