Answer 1

What you want to do is save all the variables in a custom class serialize it using link this might help you.

Answer 2

You can put all the important data in a state class, and then serialize it to file in a binary, XML or JSON format. When your application is restarted, you can deserialize this file back to a class instance and use it.

For binary serialization look at BinaryFormatter, for XML - XmlSerializer, for JSON you can user JSON.Net

You may also need some plumbing code to rebuild caches, resubscribe to events, e.t.c.
