I have a list of books that I have grouped, summed and ordered the groups. But I can't figure out how to order the books within the groups.
I have the following:
This will group the books by genre, get a count and sum the group as well as order the groups by genre.
But the book titles are out of order.
How would I order the books inside the groups?
Thanks,
Tom
I have the following:
Code:
public class Book
{
public string Title;
public string Author;
public string Genre;
public decimal Price;
}
public class GroupCountSum<K, T, C, D>
{
public K Key;
public IEnumerable<T> Values;
public int Count;
public decimal Summed;
}
public void GroupAndSum()
{
public List<GroupCountSum<string, Book, int, decimal>> BooksCountedSummed;
public List<Book> Books = new List<Book>();
// Add test data
Books.Add(new Book { Author = "Douglas Adams", Title = "The Hitchhiker's Guide to the Galaxy", Genre = "Fiction", Price = 159.95M });
Books.Add(new Book { Author = "Scott Adams", Title = "The Dilbert Principle", Genre = "Fiction", Price = 23.95M });
Books.Add(new Book { Author = "Douglas Coupland", Title = "Generation X", Genre = "Fiction", Price = 300.00M });
Books.Add(new Book { Author = "Walter Isaacson", Title = "Steve Jobs", Genre = "Biography", Price = 219.25M });
Books.Add(new Book { Author = "Michael Freeman", Title = "The Photographer's Eye", Genre = "Photography", Price = 195.50M });
//Group the books by Genre count number of books and sum the prices
var booksGroupedCountedSummed = (from b in Books
group b by b.Genre into g
select new GroupCountSum<string, Book, int, decimal>
{
Key = g.Key,
Values = g,
Count = g.Count(),
Summed = g.Sum(x => x.Price)
}).OrderBy(g=>g.Key);
BooksCountedSummed = booksGroupedCountedSummed.ToList();
}
This will group the books by genre, get a count and sum the group as well as order the groups by genre.
But the book titles are out of order.
How would I order the books inside the groups?
