Regular expression with C#

Question

I'm attempting to find a regular expression that will match the following strings:

##Content##
##AnotherArea##

So far I've tried

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

But neither seem to find anything when running:

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

Where expression match is a string containing the expressions.

Can anyone help me out on this?

no need to escape #.

##.*?##

simple explanation

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 «##»

But I think he wants the sub-group match (or whatever that's called).

its still OK to escape it unless he uses verbatim string

Awesome, thanks a lot for the explanation as well. I know nothing about regex.
