为什么没有像 String.Empty 这样的 Char.Empty? [英] Why is there no Char.Empty like String.Empty?

问题描述

这是有原因的吗?我问是因为如果您需要使用大量空字符，那么您会遇到与使用大量空字符串时相同的情况.

Is there a reason for this? I am asking because if you needed to use lots of empty chars then you get into the same situation as you would when you use lots of empty strings.

这种用法的原因是这样的:

The reason for this usage was this:

myString.Replace ('c', '')

所以从 myString 中删除所有 'c' 的实例.

So remove all instances of 'c's from myString.

推荐答案

没有空字符这样的东西.您可以获得的最接近的是 ''，即 Unicode空"字符.鉴于您可以将它嵌入到字符串文字中或非常容易地单独表达它，为什么您需要一个单独的字段呢?同样，很容易混淆 " 和 "" 参数不适用于 ''.

There's no such thing as an empty char. The closest you can get is '', the Unicode "null" character. Given that you can embed that within string literals or express it on its own very easily, why would you want a separate field for it? Equally, the "it's easy to confuse "" and " "" arguments don't apply for ''.

如果你能举例说明你想在哪里使用它以及为什么你认为它会更好，那可能会有所帮助......

If you could give an example of where you'd want to use it and why you think it would be better, that might help...
