推荐答案

首先要注意的是你的分割操作不会分割单词，因为你不使用任何单词间隙字符在你的拆分操作中。

尝试在Split数组中添加空格，看看是否有所改进。



然后使用调试器来查看你在检查什么。



就个人而言，我不会使用正则表达式 - 我在输入上使用String.ToLower，然后使用 Enumerable.Contains [ ^ ]查看此单词是否在列表中。

The first thing to note is that your split operation doesn't split words, as you don't use any inter-word gap character in your split operation.
Try adding space to the Split array and see if that improves things.

Then use the debugger to see exactly what you are checking.

Personally, I wouldn't use a regex for this - I'd use String.ToLower on the input, and then use Enumerable.Contains[^] to see if this word is in the list.

您可以使用正则表达式来达到目的。附件是类似的例子，它搜索句子中的给定单词。你可能需要做一些调整才能得到你想要的结果。

Well you can use regular expression for your purpose. Attach is similar example which searches a given word in a sentence. You may need to do a bit tweaking to get your desired result.
