推荐答案

问题的答案：？一个普通防爆pression匹配任何不是富和栏

^(?!foo$|bar$).*

将这样做。

^      # Start of string
(?!    # Assert that it's impossible to match...
 foo   # foo, followed by
 $     # end of string
|      #
 bar$  # bar, followed by end of string.
)      # End of negative lookahead assertion
.*     # Now match anything

您可能需要设置 RegexOptions.Singleline 如果你的字符串可以包含换行符，你也想匹配。

You might need to set RegexOptions.Singleline if your string can contain newlines that you also wish to match.
