Our goal is to write a program that is more efficient, robust, and easy to maintain.C#Code. Principle 1: use attributes as much as possible (Property), Rather than data members (Field). Always use properties instead of accessible data

1. Creation Mode: Singleton: Solves the number of instantiated objects, such as factories and object pools in the abstract factory. In addition to Singleton, other creation modes solve the coupling relationship brought by new. Abstract Factory:

(According to the msdn webcast courses) This is a behavior-oriented design model that is widely used. Objects may often need different typesAlgorithm, But if the change is frequent, the type will become very fragile. As shown inCubeTake, take

(According to the msdn webcast courses) New Problem: Implementing dependencies cannot cope with changes in the specific instantiation type. (When the instance object changes, it cannot meet the requirements) Example: When a road is prone to
