如何比较字符（尊重文化） [英] How to compare characters (respecting a culture)

问题描述

有关我在此问题中的答案，我必须比较两个字符。我认为正常的 char.CompareTo（）方法允许我指定一个 CultureInfo ，但事实并非如此。

For my answer in this question I have to compare two characters. I thought that the normal char.CompareTo() method would allow me to specify a CultureInfo, but that's not the case.

所以我的问题是：如何比较两个字符并指定一个CultureInfo用于比较？

So my question is: How can I compare two characters and specify a CultureInfo for the comparison?

推荐答案

比较字符和字符串的确有一个区别。让我尝试解释一个基本的问题，这是很简单的：一个字符总是代表一个单一的unicode点。比较字符总是比较代码点，而不考虑它们的含义相同。

There is indeed a difference between comparing characters and strings. Let me try to explain the basic issue, which is quite simple: A character always represents a single unicode point. Comparing characters always compares the code points without any regard as to their equal meaning.

如果你想比较字符的含义，你需要创建一个字符串并使用比较方法。这些包括对不同文化的支持。见Guffa的答案如何做。

If you want to compare characters for equal meaning, you need to create a string and use the comparison methods provided there. These include support for different cultures. See Guffa's answer on how to do that.
