这个
“ aaaaaaaaaa ” “ bbbbbbbbbbbbb ” “ cccccccccc ” ...
是根据什么规则？

“ aaaaaaaaaa ” “ bbbbbbbbbbbbb ” 这个之后 不一定有 \par 但是是在最后一个花括号之前的。。要怎么弄呢？

[兔子-顾问]

看上去一定会有的。

不好意思，令发一帖 再问。 浪费你时间了....

[兔子-顾问]

如果\par不一定有

Regex reg2 = new Regex(@"(?<=\\cf[^ ]+\s+)\S+(?=\s*\\par|})", RegexOptions.Compiled);

[兔子-顾问]

囧，不用重发贴。

[兔子-顾问]

没有答案可以继续跟帖。刚忙，没仔细回，你规则不同继续说明即可。。
