C＃3.0自动属性，为什么不直接访问该字段？ [英] C#3.0 Automatic properties, why not access the field directly?

问题描述

采用将获取/设置设置在类的属性内的新方法：

With the new approach of having the get/set within the attribut of the class like that :

public string FirstName {
        get; set;
    }

为什么不简单地简单地将FirstName属性设置为没有访问者？

Why simply not simply put the attribute FirstName public without accessor?

推荐答案

直接访问类内部变量（字段/属性）的两个主要问题是：

Two of the big problems with direct access to variable inside class (field/attribute) are:

1）您无法轻松地对字段进行数据绑定。

1) You can't easily databind against fields.

2）如果您从类中公开了公共字段，则以后就无法将其更改为属性（例如：向验证员添加验证逻辑）

2) If you expose public fields from your classes you can't later change them to properties (for example: to add validation logic to the setters)
