Can I select multiple objects in a Linq query

Question

Can I return more than one item in a select? For instance I have a List of Fixtures (think football (or soccer for the yanks) fixtures). Each fixture contains a home and away t

Answer 1

I came up against this very issue, and couldn't find what I wanted so I wrote a small extension method which did what I wanted.

public static IEnumerable MapCombine(this IEnumerable origList, params Func[] maps)
{
    foreach (var item in origList)
    foreach (var map in maps)
    {
        yield return map(item);
    }
}

Following the problem in the question, you would then do something like this

var drew = fixtures.Where(fixture => fixture.Played && 
                        (fixture.HomeScore == fixture.AwayScore))
                    .MapCombine(f => f.HomeTeam, f => f.AwayTeam);

Interestingly intellisense isn't exactly happy about this, you don't get the lamdba expression in the top of the drop down, however after the '=>' its quite happy. But the main thing is the compiler is happy.
