用C#正则表达式

Question

我正在尝试找到一个与以下字符串匹配的正则表达式:

##Content##
##AnotherArea##

到目前为止我已经尝试过了

@"\\#\\#(.*?)\\#\\#"
@"\\#\\#(*?)\\#\\#"

但是在跑步时似乎都找不到任何东西:

foreach (var match in Regex.Matches(txtPageContent.Text, expressionMatch))

表达式匹配是包含表达式的字符串.

任何人都可以帮我解决这个问题吗？

没有必要逃脱#.

##.*?##

简单的解释

Options: ^ and $ match at line breaks

Match the characters “##” literally «##»
Match any single character that is not a line break character «.*?»
   Between zero and unlimited times, as few times as possible, expanding as needed (lazy) «*?»
Match the characters “##” literally «##»
