什么是一个好的规则，什么时候添加成员与'this'（C＃）？ [英] What is a good rule for when to prepend members with 'this' (C#)?

问题描述

如果我正在访问某个成员字段，属性或方法，我无法确定我应该在其前面加上this。

If I am accessing a member field, property, or method, I'm never sure when I should prepend it with 'this'.

关于需要它的情况，例如在局部变量具有相同名称的情况下。我在说的意思是完全一样的情况。哪个更可读？有没有任何标准，最佳做法或经验法则我应该遵循？

I am not asking about cases where it is required, like in the case where a local variable has the same name. I am talking about cases where the meaning is exactly the same. Which is more readable? Are there any standards, best practices, or rules of thumb I should be following? Should it just be consistent throughout a class, or an entire code base?

推荐答案

我建议使用Microsoft的指南，如StyleCop验证的那样： http://blogs.msdn.com/sourceanalysis/

一般的规则是，用this前缀成员。

The general rule is, prepend members with "this." when they are defined in the class, unless they are static, in which case you cannot.

这里是直接来自StyleCop的规则：

Here is the rule directly from StyleCop:

SA1101: The call to {method or property name} must begin with the
'this.' prefix to indicate that the item is a member of the class.
