使用仅带有属性和构造函数的类 [英] use of a class with just properties and constructors

问题描述

仅具有属性和构造函数且没有方法的类的用途是什么?
请详细说明或参考...
实际上，我已经分配了一个维护项目.我在该项目中看到了很多这样的类.


问候.

What is the use of a class with just properties and constructors and NO METHODS ?
Please explain in detail or refer...
Actually, I have been assigned a project for maintainence. and i see a lot of such classes in that project.

推荐答案

难怪，我已经看到这样的类用于简单地存储有关各种实体的信息(例如C ++中的结构-C#结构非常罕见).或多次传递参数.这些类可以稍后进行序列化，写入数据库或从数据库中读取(等等，后者更常见，有些人只是喜欢将数据库结构映射到类结构:)).

No wonder, I''ve seen such classes being used to simply store information about various entities (like structs in C++ - C# structs are quite rare) or to pass arguments many times. These classes could later be serialized, written to/read from database etc (the latter more often, it some people just love to map database structure to class structure :) ).

通常，它们要么只是存储相关信息并将其保持在一起，要么是从现有的类派生而来-添加功能而不添加功能.例如，一个类可以从List派生而没有添加任何方法:

Generally, they are to either just store relevant information and keep it together, or to derive from an existing class - adding functionality without adding functions. For example a class could derive from List and add no methods:

public class Students : List<student>
   {
   public string ClassName { get; set; }
   }
