Collections Question (.NET 3.5, C#)

Question

I'm stuck and I need help. Anyway I have Visual Studio 2008 console program that needs to log a Date, String, Boolean, and an integer for each round of a game. Say the user plays 10 rounds I would have 10 of each.

I want to save those records in a data structure (collection i believe) and then after the game is finished loop through them producing a simple console report.

I'm stuck. It seems like a simple thing, but I can't find the solution. I imagine that there are multiple ways to accomplish this, but I'm looking for the most simple solution.

Answer 1

Edit: I wanted to simplify the answer to this, but perhaps I simplified too much. I've changed the mutable struct below (which is a bad idea, thanks for reminding me @Jon Skeet), with a class, and properties as well.

First, create the data type to hold the information:

public class RoundInformation
{
    public DateTime Date { get; set; }
    public String Name { get; set; }
    public Boolean DidCheat { get; set; }
}

Then create the list to hold it:

public List<RoundInformation> Rounds = new List<RoundInformation>();

Then, for each round, construct a value with the round information data and add it to the list:

RoundInformation info = new RoundInformation();
info.Date = DateTime.Now;
info.Name = "Bob";
info.DidCheat = true; // Bob always cheats
Rounds.Add(info);

To loop through:

foreach (RoundInformation round in Rounds)
{
    .. dump to console, left as an excercise
}

Answer 2

Try this:

public class GameRound {
    public DateTime Date {get; set;}
    public string String {get; set;}
    public bool Boolean { get; set;}
    public int Integer { get; set; }
}

In one part, with the correct variable names.

Then, in your console program, add the following line at the top:

List<GameRound> rounds = new List<GameRound>();

This makes a "list" of rounds, which can be added to, removed, and "looped" through.

Then, when you want to add a round, use code like this:

rounds.Add(new GameRound { Date = theDate, String = theString, Boolean = theBool, Integer = theInt });

This makes a new GameRound object, and sets all the properties to values. Remember to substitute theDate, etc. for the correct names/values.

Finally, to produce the report, try this:

foreach ( GameRound round in rounds ) {
    Console.WriteLine("Date: {0}\nString: {1}\nBoolean: {2}\nInteger: {3}", round.Date, round.String, round.Boolean, round.Integer);
}
