如果已将私有变量标记为私有变量，该怎么办？ [英] What for should I mark private variables as private if they already are?

问题描述

  class Foo 
 {
私人字符串栏; 
} 
 
 class Foo 
 {
 string bar; 
} 
  

我猜这两个声明是一样的。

所以我的问题是：如果私有变量已经是私人的，那么我应该如何将私有变量标记为 private ？

解决方案

我已经在围栏上一段时间了。我曾经争辩说是隐含的，但现在我觉得我倾向于明确表达。

隐藏的原因：

• 这意味着非私人会员（或者比默认访问权限更多的内容）有更大的差异;这显示了阅读代码时的区别

显示原因：

• 某些开发人员可能不知道默认值：明确表示


• 它表明您已经积极地作出了决定，而不是仅仅将其保留为默认值。

这些后一点是基本上是由Eric Lippert制作的，当我们之前讨论过的时候。

As far as I know, in C# all fields are private for default, if not marked otherwise.

class Foo
{
  private string bar;
}

class Foo
{
  string bar;
}

I guess these two declarations are equal.

So my question is: what for should I mark private variables as private if they already are private?

解决方案

I've been on the fence for a while about this. I used to argue for leaving it implicit, but now I think I'm tipped over towards making it explicit.

Reasons for leaving it implicit:

• It means there's a bigger difference for non-private members (or anything with more access than the default); this highlights the difference when reading the code

Reasons for making it explicit:

• Some developers may not know the defaults: making it explicit means it's clear to everyone
• It shows you've actively made a decision, rather than just leaving it up to the default

These latter points are basically the ones made by Eric Lippert when we discussed it a while ago.
