phil.o has given you the documentation, but if you look at your line text, the section you want starts at index 25 (starting form zero, remember) and is 9 characters long. So those are the numbers you feed into substring to specific exactly which chunk of text you want to extract.
A Regex will do fine, but they can be complicated and difficult to understand (and worse to modify), so it you can use a "fixed position" extraction for now, that's the best place to start.

The ReadLines and ReadAllLines methods differ as follows: When you use ReadLines, you can start enumerating the collection of strings before the whole collection is returned; when you use ReadAllLines, you must wait for the whole array of strings be returned before you can access the array. Therefore, when you are working with very large files, ReadLines can be more efficient.

Then you need to go back to the original message and edit it with proper details of what you are looking for. No one guess from "I need code" exactly what problem you are trying to solve. Keep in mind that we cannot see your screen, or know anything about your project, so the only details we can work on is what you tell us.
I am writing a tiny app which will be triggered in GPO by a user logoff. The app simply checks that the user has done some required housework. Can anyone show me how to interrupt the logoff (and remain logged on) depending on the answer?
There is no way to absolutely prevent a user from logging off or shutting down the system.
Even the solution you found is a "suggestion" that the system not shutdown. There is nothing you can do to prevent it as everything you come up with can be defeated just by ending the process that is your application.
