Regex: Match everything after first blank line

Question

I am trying to create a regex that matches everything after but not including the first blank line in c#.

Example:

having input of:

This is header info
that I dont'  : really want
in my file

I want everything below this line
until the end of the file

even this stuff

would result in:

I want everything below this line
until the end of the file

even this stuff

Answer 1

You can use single line and multiline flag in a regex like this:

^$.*

Working demo

Btw, if you have multiple white spaces in the line, then you could use:

^\s*$(.*)

And then grab the content from the capturing group
