Question

I want to sort my posts to show most viewed posts grouped by date, so that top viewed posts each day appear then the next then the next.

How to write this query in linq? method based if possible.

Answer 1

int postsPerDay = 5;

var topPostsByDate = Posts
    .GroupBy(post => post.Date)
    .Select(grp => new
        {
            Date = grp.Key,
            TopPosts = grp
                .OrderByDescending(post => post.Views)
                .Take(postsPerDay)
                .Select(post => new Post(post))
        })
    .OrderByDescending(x => x.Date);

EDIT: Constructs a new Post object from the data row. Assumes that Post has a constructor accepting a DataRow; alter to fit.
