c# - Regex: Match everything after first blank line -

i trying create regex matches after not including first blank line in c#.

example:

having input of:

this header info dont'  : want in file  want below line until end of file  stuff 

would result in:

i want below line until end of file  stuff 

you can use single line , multiline flag in regex this:

^$.* 

working demo

btw, if have multiple white spaces in line, use:

^\s*$(.*) 

and grab content capturing group
