c# - 找到匹配的单词

Question

我有这段代码，我在字符串中搜索数组中的单词:

string wordlist = synonymslistbox.Items[q_index].ToString().Split(':')[0].Replace(',', ' ');

var pattern = new Regex(@"\W");

var qa = pattern.Split(first_sentence).Any(w => wordlist.Contains(w));

现在我想实现两件事，但我不知道该怎么做。

1. 找出匹配的单词。此代码仅在找到时返回 true。
2. 当 first_sentences 是 i like my banjo 时，它不应该在 banjo 中找到字母 a 作为单词 a。当 a 在这样的句子中时，它应该只读为一个单词:i like a big beer at the end of the afternoon。

Answer 1

1. find out witch word was a match. this one just returns true if found.

代替任何，使用where:

var qa = pattern.Split(first_sentence).Where(w => wordlist.Contains(w));

2. when first_sentences is "i like my banjo" then it should NOT find a in banjo as the word a. it should only read a as a single word when it is in a sentence like this below "i like a big beer at the end of the afternoon"

您的单词列表不应是字符串，而应是字符串列表或数组。确保它是一个包含“a”的列表。除此之外，您的代码将起作用
