Reflection combines with effective object-oriented design to allow programs to be more flexible. Delegation is useful because it allows an object to change behavior at runtime. This change in behavior happens when one delegate that provides one behavior is replaced with another delegate that provides a different behavior. The number of different delegates available defines the amount that this behavior can vary.
Without reflective mechanisms, the number of delegates is limited to only the set of classes that are included in the system at comple time. Reflection increases this range of variation by allowing the system to use classes that are written later. There are several noteworthy aspects of this relationship:
