Question

Let’s use this query as an example (this comes from the MSDN docs):

ObjectSet<SalesOrderHeader> orders = context.SalesOrderHeaders;
ObjectSet<SalesOrderDetail> details = context.SalesOrderDetails;

var query =
    from order in orders
    join detail in details
    on order.SalesOrderID equals detail.SalesOrderID
    where order.OnlineOrderFlag == true
    && order.OrderDate.Month == 8
    select new
    {
        SalesOrderID = order.SalesOrderID,
        SalesOrderDetailID = detail.SalesOrderDetailID,
        OrderDate = order.OrderDate,
        ProductID = detail.ProductID
    };

If I wanted to put all the fields present in “order” into the final object (i.e. the select new) in addition to the additional fields from detail, how would I do it?

Answer 1

var query =
    from order in orders
    join detail in details
    on order.SalesOrderID equals detail.SalesOrderID
    where order.OnlineOrderFlag == true
    && order.OrderDate.Month == 8
    select new
    {
        SalesOrderHeader = order;
        SalesOrderDetail = detail;
    };
