. Net six design principles personal vernacular understanding, please correct if there is any error

Opening and closing principle ： On the extension , Close... To modification , Interface is a good example , It can be extended on the basis of the source code , But you can't change the source code

A single principle ： Single function , A class represents a function .

The Ritchie principle ： Subclasses can be used as parent classes , Subclasses need to inherit all methods of the parent class

The principle of Dependence Inversion ： Rely on abstract interfaces , Don't rely on concrete implementation , Try to use interfaces to encapsulate common ground

Interface isolation principle ： Split bloated interfaces into smaller and more specific interfaces , It is not a method with high commonality that is pulled out and encapsulated into an interface ,
You need to use the methods in the new interface to inherit the new interface , If you put many subclasses in an interface, you don't need some methods inside , It seems that this interface is relatively bloated ,
Don't put all methods into the same interface in order to save trouble .

Dimitar's law ： Reduce coupling between classes . Each class minimizes dependencies on other classes , Make the function module function as independent as possible . For example, you need to pass the class 1 Display methods display classes 1 And the class 2 The data of
Don't be in class 1 Write the display class directly in 2 Logical code of , But in class 2 Finish writing the display class 2 Methods , Then it is passed to the class in the form of parameters 1 The presentation method of a class 2 The object of ,
Then call class 2 How to show
