Reference namespace shortcut key: Shift + Alt +f10;Value types and reference types:Difference:1, value types and reference types are not stored in the same place in memory;2, when passing value types and passing reference types, the way they are

First, the object-oriented basisObject-oriented noun interpretation: class: used to describe a collection of objects that have the same properties and methods. It defines the properties and methods that are common to each object in the

Process oriented: Write base code from top to bottom according to business logicFunction: A function code is encapsulated in a function, it will not need to be repeated later, only the function can be calledObject-oriented: classify and encapsulate

Now the mainstream language of programming is basically object-oriented. such as C#,c++,java. When we use it, we have constructed a class. But often because of our internal or external design problems in the class, resulting in the object-oriented

Explain:There must have been a lot of doubts about the name of this principle as I have just seen it. The reason is that the principle was first introduced in 1988 by a woman surnamed Barbara Liskov of MIT.Definition 1: If for each object of type T1,

Short for solid1. Single Responsibility PrincipleResponsibility is defined as the cause of the change. A class, it is best to do only one thing, only a change that causes it. Do not implement too many functional points for the class to ensure that

Virtual machine byte code execution engine1. All Java Virtual machine execution engines are consistent: the input is a bytecode file, processing is the efficient process of byte code parsing, the output is the execution results.2. Runtime stack

Microsoft's entity Framework is being watched and used by more and more people, and the entity Framework7.0 version is about to be released. Although it is open source, unfortunately, there is no book about it, let alone a good book, probably

Object-oriented is a computer programming architecture, which is more flexible and extensible than process-oriented editing. Here to remind beginners: to be in the programming this way to go farther than others, you must master the object-oriented

The Singleton mode, as its name implies, has only one instance. As the object creation mode, the singleton mode ensures that a class has only one instance, and the instance is self-instantiated and provided to the entire system. 1. Singleton

This example may not be practical, but it basically outlines the three characteristics of object-oriented: inheritance, encapsulation, polymorphism. The main functions of this example are: Allows users to select different types of graphics;
