Question

I am having trouble converting this code into extension method syntax:

var query = from c in _context.Customers
                        from o in c.Orders
                        where o.DateSent == null
                        select new CustomerSummary
                        {
                            Id = c.Id,
                            Username = c.Username,
                            OutstandingOrderCount = c.Orders.Count
                        };

Any ideas?

Answer 1

var query = _context.Customer
  .Where(c => c.Orders.Any(o => o.DateSent == null))
  .Select(c => new CustomerSummary
  {
    Id = c.Id,
    Username = c.Username,
    OutstandingOrderCount = c.Orders.Count(o => o.DateSent == null)
  };
