Hello,

I have three tables: Polls (PollId, Question), Options (OptionID,
Answer) and Votes (VoteID, OptionID)

I then created two Wrapper Classes:

PostPaper with the following properties:
public Poll Poll { get; set; }
public List<OptionPape rOptions { get; set; }
public string OptionsCSV { get; set; }

OptionPaper with the following properties:
public Option Option { get; set; }
public int Votes { get; set; }

I need, given an PollId, to get fill a PostPaper with all its options
and for each option count the votes:

pollViewData.Po llPaper = (from p in database.Polls
join o in database.Option s on p.PollID
equals o.PollID
join v in database.Votes on o.OptionID
equals v.OptionID
where p.PollID == id
group o by p into pog
select new PollPaper {
Poll =
pog.Key,
Options = new List<OptionPape r{
Option = ??????
Votes = ?????
}.ToList(),
OptionsCSV = string.Join(", ",
pog.Select(o =o.Answer).ToAr ray())
}).SingleOrDefa ult();

I am having problems in creating the Option and Count the votes of
each OptionPaper in List Options.

Could someone, please, help me out?

Thanks,
Miguel

I've come up with something like this:

PostPaper pp = new PostPaper();
pp.Poll = (from p in Polls where p.PollID == pollID select p).First();
var opts = (from o in Options where o.PollID == pollID select o);

OptionPaper op;
foreach (Option o in Options)
{
op = new OptionPaper();
op.Option = o;
op.Votes = (from v in Votes where v.OptionID == o.OptionID select
v).Count();
pp.Options.Add( op);
}

I am using the following:

PollPaper paper = (from p in database.Polls
where p.PollID == id
select new PollPaper {
Poll = p,
OptionsCSV = string.Join("," ,
p.Options.Selec t(op =op.Answer).ToA rray()),
Options = (from o in p.Options
select new OptionPaper() {
Option = o,
Votes = o.Votes.Count
}).ToList()
}).SingleOrDefa ult();

In think it is ok ... but could someone give me some feedback?

Thanks,
Miguel
