C# Store variables after program closes

Question

Is there any simple way to store variable when my game closes and load it when it opens next time? Even better would be if I could store instance of my class and then load it.

See http://stackoverflow.com/questions/4266875/how-to-quickly-save-load-class-instance-to-file or http://stackoverflow.com/questions/6115721/how-to-save-restore-serializable-object-to-from-file. — Mihai8, May 18 '14 at 12:37
What do you want to store? Is this like a saved game, or are these settings for how your application should run? — just.another.programmer, May 18 '14 at 12:38
You could serilize your class and read it next time the game gets started — Kimmax, May 18 '14 at 12:39
You could try the Settings class http://msdn.microsoft.com/en-us/library/aa730869%28v=vs.80%29.aspx Scroll down to the bit about using settings at run time — user184994, May 18 '14 at 12:41
There are too many ways to do this, though given your wish, serialisation and dumpt to a file looks like the best one. — Tony Hopkinson, May 18 '14 at 12:51

You can serialize the object to an .xml file or to a DB and on load deserialize it and you will have the object in the memory.

You can use Json.NET to serialize the instance of a class. And upon loading all you have to do is deserialize it, everything is done by the library.

Serialization example:

Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Sizes = new string[] { "Small" };

string json = JsonConvert.SerializeObject(product);
//{
//  "Name": "Apple",
//  "Expiry": "2008-12-28T00:00:00",
//  "Sizes": [
//    "Small"
//  ]
//}

Deserialization example:

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}";

Movie m = JsonConvert.DeserializeObject<Movie>(json);

string name = m.Name;
