如何在C＃中使用正則表達式來拆分此行

Question

輸入

-n. 1 geographical map or plan, esp. for navigation. 2 sheet of information in the form of a table, graph, or diagram. 3 (usu. in pl.) colloq. listing of the currently best-selling pop records. -v. make a chart of, map. [Latin charta: related to *card1]

我需要分割該這樣
-n.
1 geographical map or plan, esp. for navigation.
2 sheet of information in the form of a table, graph, or diagram.
3 (usu. in pl.) colloq. listing of the currently best-selling pop records.
-v.
make a chart of, map. [Latin charta: related to *card1]

我的表情是這裏 ((—\w\.)|(\d\s))(([^\d—])*)

但這未能對card1]

如何解決這個問題？

如何否定digit followed with space？

Answer 1

利用前瞻：

((-\w\.)|(\d\s))(([^\d-]|(\d(?!\s))|(-(?!\w\.)))*) 

你想要的任何數量的非數字或非破折號（[^\d-]），但你也希望允許不跟空格(\d(?!\s))和連字符是不是活得位t之後是字符和句點(-(?!\w\.))。

Answer 2

你應該對你的輸入字符串做Regex.Escape。
