Question

“ > 我愿用一个<条码>和取代所有这些编号。能否通过利用Regex来做到这一点?

我正在使用这一条例,但未能做到:

@"(?<word>w+)s+(k<word>)"

Answer 1

Regex.Replace(text, @"(ands+)+", "and ");

Answer 2

如果你说,一般重复的话(如你职位上的格言):

resultString = Regex.Replace(subjectString, @"(w+)(?:s+1)+", "$1");

<>Explanation:

    # Assert start at a word boundary
(w+) # Match a word
(?:   # Try to match...
 s+  # Whitespace and
 1   # the same word as before
)+    # one or more times
    # Assert end at a word boundary

仅限<代码>和请替换:

resultString = Regex.Replace(subjectString, @"(?:ands+){2,}", "and ");

Answer 3

与此类似:@”(ands+){2,}>(未经测试)。或者,由于你重新搜索/放置任何航道,@”(和s+)+。
