Linq - Count

[shapper]

Hello,

I have three tables with the following columns:
Polls (PollID, Question)
Options (OptionID, PollID, Answer)
Votes (VoteID, OptionID)

Then I have two wappers around Polls and Options, named PollPaper and
OptionsPaper:
public class PollPaper {
public Poll Poll { get; set; }
public List<OptionPaperOptions { get; set; }
public string OptionsCSV { get; set; }
public int Votes { get; set; }
}

public class OptionPaper {
public Option Option { get; set; }
public int Votes { get; set; }
public double Share { get; set; }
}

I am using the following Linq query to get all information from a
poll:

PollPaper paper = (from p in database.Polls
where p.PollID == id
select new PollPaper {
Poll = p,
Votes = ?????
OptionsCSV = string.Join(",",
p.Options.Select(op =op.Answer).ToArray()),
Options = (from o in p.Options
select new OptionPaper()
{
Option = o,
Votes = o.Votes.Count,
Share =
o.Votes.Count / ??? *
100
}).ToList()
}).SingleOrDefault();

Basically, I don't know how to count the total votes on that poll and
then use it to calculate the share of each poll option ... Basiclly,
fill the ???.

Does anyone knows how to do this?

Thanks,
Miguel

OK, given the number of times you've posted this, I think we can
assume that there isn't a clear way to do what you want (or even,
perhaps, understand your setup fully).

Rather than post the same thing indefinitely, how about trying a more
LINQ-specific forum? This isn't really a C# language question...
