Attributes are an example of Decorator?

The decorator pattern applies when there is a need to dynamically add responsibilitie开发者_运维百科s to a class, and when subclassing would be impossible due to the large number of subclasses that could result.

Given above definition I would think attributes is decorator. Or could it be considered Proxy or Adapter?

Thoughts?

Yes, .NET attributes are basically their way of implementing the decorator pattern.
