Nested classes and business logic in a repository?

Question

For my application I need to store some data in an array with the properties (string main, string[] status, int curParCount, etc.).

I am currently storing it in this class:

class Repository
{
    public static Rep[] rep = new Rep[6];
    public struct Rep
    {
        public string main;
        public string clean;
        public int curParCount;
        public int totalCount;
        public int parStart;
        public int partialStart;
        public double scrollPos;
        public int selectionStart;
        public int selectionEnd;
        public string[] status;
    }    
    public static string repName()
    {
        string name;
        if (MainWindow.repnum == 0)
        { name = "Main Text"; }
        else { name = "Repository " + MainWindow.repnum; }
        return name;
    }
    public static string getStatus(int repNum, int statNum)
    {
        return rep[repNum].status[statNum];
    }                                                                  
 }

Is this the right way for me to do this? It sure doesn't feel like it is.

Answer 1

The basic idea is fine. The implementation could be improved. In particular, I'm concerned that you have a mutable struct; either make it immutable or turn it into a class. I'd also recommend changing the public fields into public properties with automatic backing fields (and then upper-casing the names).

Here's my version:

class Repository
{
    public class Rep
    {
        public string Main {get; set;}
        public string Clean {get; set;}
        public int CurParCount {get; set;}
        public int TotalCount {get; set;}
        public int ParStart {get; set;}
        public int PartialStart {get; set;}
        public double ScrollPos {get; set;}
        public int SelectionStart {get; set;}
        public int SelectionEnd {get; set;}
        public string[] Statuses {get; set;}
    }                                       


    public const int StatusCount = 6;
    public static List<Rep> Reps = new List<Rep>();

    public static string Name
    {
        get
        { 
            if (MainWindow.repnum == 0)
              return "Main Text";

            return "Repository " + MainWindow.repnum;
        }
    }

    public static string GetStatus(int repIndex, int statIndex)
    { return Reps[repIndex].Status[statIndex]; }
}
