Find strings following a pattern in a text file using C# -

i'm looking way search through huge text file , extract couple of strings follow pattern, write each of strings individual lines in text file.

is there equivalent of linux grep command, combined *, -, ^, [], etc. symbols in c# ?

i hope place type of open questions. thank !

firstly, if it's large file, use file.readlines() scan lazy loads small amounts of data @ time, giving 1 line @ time process.

then match items, use c#'s regular expression functionality.

you'll end like:

var regex = new regex(-- match expression --); foreach (var line in file.readlines("somefile").where(line => regex.match(line).success))  {     file.appendalltext("file write to", line + environment.newline); }
