Answer 1

Use whatever you and your team find the most readable.

(使用您和您的团队最容易阅读的内容。)

Other answers have suggested that a new string is created every time you use "" .

(其他答案表明，每次使用""都会创建一个新字符串。)

This is not true - due to string interning, it will be created either once per assembly or once per AppDomain (or possibly once for the whole process - not sure on that front).

(这是不正确的-由于字符串内部操作，它会针对每个程序集创建一次，也可能针对每个AppDomain创建一次（或者对于整个过程可能创建一次-不确定在那方面）。)

This difference is negligible - massively, massively insignificant.

(这种差异可以忽略不计-在很大程度上，在很大程度上是微不足道的。)

Which you find more readable is a different matter, however.

(但是，您发现更具可读性的是另一回事。)

It's subjective and will vary from person to person - so I suggest you find out what most people on your team like, and all go with that for consistency.

(它是主观的，并且因人而异-因此，我建议您找出团队中大多数人都喜欢的东西，并且为了保持一致性，所有人都应该这样做。)

Personally I find "" easier to read.

(我个人觉得""更易于阅读。)

The argument that "" and " " are easily mistaken for each other doesn't really wash with me.

(""和" "容易被误认为是我的观点。)

Unless you're using a proportional font (and I haven't worked with any developers who do) it's pretty easy to tell the difference.

(除非您使用比例字体（并且我没有与任何开发者合作过），否则很容易分辨出区别。)
