自动属性与简单变量 [英] Automatic properties vs simple varible

问题描述

你好

自动属性和变量之间有什么区别?

What is differences between automatic properties and variable?

我读了这个过时的话:

在C#代码库中看不到自动生成的私人支持字段的名称.看到它的唯一方法是使用诸如ildasm.exe之类的工具.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace _05_static
{
    class Program
    {

        public int number { get; set; }
        public int num;

        static void Main(string[] args)
        {
           
        
    }
}
}

推荐答案

属性公开了一个后备字段.出于封装原因，您应该使用属性来公开它(而不是公开该字段(变量)本身).请参考以下链接以获取更多信息: http://stackoverflow.com/questions/295104/what-is-the-difference-between-a-field-and-a-property-in-c

A property exposes a backing field. Instead of exposing the field (variable) itself, you should expose it using a property for encapsulation reasons.

自动或自动实现的属性只是定义属性的一种更短，更简洁的方法.实际上，编译器会在构建应用程序时自动为您创建一个支持字段.请参阅以下页面以获取更多信息: https://msdn.microsoft.com/en-us/library/bb384054.aspx

An automatic or auto-implemented property is just a shorter and more concise way of defining a property. The compiler will actually create a backing field for you automatically when you build the application.

>> 自动生成的私有支持字段的名称在您的C#代码库中不可见.看到它的唯一方法是使用诸如ildasm.exe之类的工具.

由于后勤字段是在编译时自动生成的，因此您无法在代码中看到它.

Since the backing field gets generated automatically at compile-time, you cannot see it in your code.

希望有帮助.
