I'm guessing you want to use a combination of TextReader to read the text from the file and RegEx to match the pattern.

It would be difficult to give you any examples since you don't provide any exact details.

You can always use a regular expression in order to do it, but perhaps i didn't understand the question..

You can use Regular Expressions to find any pattern. A tutorial can be found here: http://dotnetperls.com/regex-file

• Use File.ReadAllText() to read the content.
• Use Regex.Matches() to look for the pattern.
