.NET RegEx用标记替换转义字符

Question

I have some text from an old database. The text is formatted like this:

This is the first part of the text #this should be formatted in bold# this should be normal text and then #this should be formatted in bold again# and so on.

As you can see above, I need to find all the groups that are inside # signs, and set a <b></b> or <strong></strong> tag around them. How can I do this in C#?

Answer 1

string input = @"This is the first part of the text #this should be formatted in bold# this should be normal text and then #this should be formatted in bold again# and so on.";
var output = Regex.Replace(input, @"#(.+?)#", "<b>$1</b>");
