C# Create a .NET object for JSON serialization and deserialization [duplicate]

Answer 1

I'll take a shot at it.

First up we'll need a model for our user:

public class User
{
    public Guid Id { get; set; }
    public string Username { get; set; }
    public string NickName { get; set; }
    public int Points { get ;set; }
    public int Hours { get; set; }
}

Then in your main method, or wherever you deal with your users:

List users = new List();

Notice that I've added an Id property. Even though your usernames might very well be unique, it's always good practice to have some sort of property whose entire job is to just be the Id. This property should never change throughout the lifetime of the user. Where username might change one day, the Id will always stay the same.

Anyways, now to turn your list into Json:

string myJsonString = JsonConvert.SerializeObject(users, Formatting.Indented);

Et voila! Your list of users is now in a tidy Json string. The above line of code is from JSON.NET, you can get it as a Nuget package. The full qualification is Newtonsoft.Json.JsonConvert. You can pretty much trust JSON.NET to handle almost anything you throw at it, especially for a simple User class like you're going to be throwing at it.

Hope this helps get you started.
