匹配以下正則表達式：＃*：*＃

Question

我想查找一個字符串是否包含以散列（＃）開頭和結尾的正則表達式幷包含冒號（:)。所有這些必須在同一行相匹配

例子：打招呼#some：測試＃和喬治MATCH

例子：打招呼＃：＃世界敵不過

實施例：打招呼#TEST：＃世界NO MATCH

實施例：你好＃：測試＃世界NO MATCH

實施例：

你好[換行符]

到#some：試驗＃世界NO MATCH

謝謝， Yannis

Answer 1

這個應該這樣做：

@"\#.+:.+\#" 

擊穿：

\# - Match a # character 
.+ - Followed by one or more characters 
: - Followed by a : character 
.+ - Followed by one or more characters 
\# - Followed by a # character 

注意.將匹配任何性格和可能不是最有效的正則表達式。

非貪婪版本（更有效）：

@"\#[^:]+:[^#]+\#" 

\# - Match a # character 
[^:]+ - Followed by one or more characters that are not : 
:  - Followed by a : character 
[^#]+ - Followed by one or more characters that are not # 
\# - Followed by a # character
