抽象类中的属性可见性 [英] Property visibility in abstract class

问题描述

有人知道在抽象类或父类中在公共属性后面定义属性可见性(私有或受保护)的方式的 C# 最佳实践吗.

Does someone knows C# best practice about the way to define attribute visibility (private or protected) behind public property in abstract class or parent class.

在其他世界中，默认情况下的最佳实践是什么(以及为什么):

In other worlds what is the best practice by default (and why) between:

public abstract class MyClass
{
    private string myAttribute;

    public string MyAttribute
    {
        get { return myAttribute; }
        set { myAttribute = value; }
    }
}

和

public abstract class MyClass
{
    protected string myAttribute;

    public string MyAttribute
    {
        get { return myAttribute; }
        set { myAttribute = value; }
    }
}

我认为子类应该有办法直接处理这个受保护的属性，但如果 getter 或 setter 包含更多代码，这可能不是一个好习惯...

I think children class should have the way to handle directly this protected attribute but it may not be a good practice if getter or setter contains more code...

你怎么看?

谢谢.

推荐答案

非常量字段应该始终是私有的.如果由于某种原因无法使用自动属性而需要使用某个字段，请确保它是私有的.子类应该通过公共或受保护的属性访问它.

Non-const fields should be really always private. If you need to use a field because you cannot use auto-properties for some reason, make sure it's private. Children classes should access it via public or protected properties.
