C # object-oriented model design lecture 1: Command command mode (behavior mode)

(According to the msdn webcast courses)

There is often a coupling relationship between object and behavior operations.

The behavior requestor uses a "command" to execute certain behaviors.

Gof: encapsulate a request into an object so that we can use different requestsProgramPerform parameterized operations, queue requests or record logs, and support unrecoverable operations.

Call the clientprogram's tightly coupled call to receive. Action () into a call to a specific command object (concretecommand object), so as to effectively manage changeable behaviors.

Arraylist or stack is used to manage abstract behaviors.
