. NET design pattern: Observer mode (Observer pattern)

Overview in the software build process, we need to create a "notification dependency" for some objects--the state of an object (the target object) changes, and all dependent objects (Observer objects) are notified.

Intent defines a one-to-many dependency between objects, and when the state of an object changes, all dependencies ...
