CompareTo函数的行为不符合我在C#中的预期 [英] CompareTo function does not behave as I expected in C#

问题描述

"01:00" .CompareTo(-1:00")

那应该是1，但是在C#中是-1.

有人可以告诉我为什么吗?否则，我根本就不敢使用它们.

"01:00".CompareTo("-1:00")

That is supposed to be 1, but it''s -1 in C#.

Can someone tell me why? Otherwise I can''t trust to use them at all.

推荐答案

您正在进行字符串比较.字符串比较以单词排序顺序"完成，这是一种与文化相关的事情，连字符被忽略.请参阅 MSDN [

You''re doing a string comparison. String comparisons are done in ''word sort order'', which is a culture dependent thing and hyphens are ignored. See MSDN[^].

You probably wanted a numeric or DateTime comparison. String comparisons are not generally a good idea.
