object oriented concepts in c#

members is proper. Next we will look at the third feature:Polymorphism.Polymorphism indicates that different objects can execute the same action, but they must use their own implementation code. When learning polymorphism, pay attention to three points: first, the Child class appears as the parent class, second, the subclass is implemented in its own way during work. When the third subclass appears as a parent class, its unique attributes and methods cannot be used, which sounds hard to unders

C language uses void type pointer to implement object-oriented class concepts and abstractions ., Void object-oriented When C ++ is not used, many new users may think that the

NOA class cannot support multiple inheritance.What is multiple inheritance?

1. Object-oriented conceptsobjects (object-oriented; OO) have not yet unified the concept, I define it here: according to people to understand the objective world of system thinking, using the concept of object-based (entity) to build a model, The method of simulating the ob

differences between abstract class and interface in the design concept, other irrelevant issues are simplified or ignored.) The following describes possible solutions and analyzes these solutions at the design concept layer. Solution 1: Add an alarm method to the door definition as follows: Abstract class door { Abstract void open (); Abstract void close (); Abstract void alarm (); } Or Interface door { Void open (); Void close (); Void alarm (); } The alarmdoor with alarm function is def

OO thought has long been in the Unix world: UNIX abstracts devices into files, so that you can use the same method (open, read, write, close ,...) access different devices and files-despite the large differences between devices. From OO's point of view, these "devices" all implement "File Operation interfaces". We can imagine that there is a base class called "file", which defines "File Operation interfaces ", the "device" object inherits the "file"

Object-oriented technology is used to simulate the genetic mechanism in the biological field. 1. Inheritance 1.1 Basic inheritance relationships (similar to inheritance) 1.2 inheritance in C # Multi-inheritance of classes is not supported (picture on the left) Only members with public, protected, and internal access modifiers in the parent class can be
