data filter using dataloadoptions
- by Tassadaque
Using dataloadoptions i have tried the following example
Northwnd db = new Northwnd(@"northwnd.mdf");
// Preload Orders for Customer.
// One directive per relationship to be preloaded.
DataLoadOptions ds = new DataLoadOptions();
ds.LoadWith<Customer>(c => c.Orders);
ds.AssociateWith<Customer>
(c => c.Orders.Where(p => p.ShippedDate != DateTime.Today));
db.LoadOptions = ds;
var custQuery =
from cust in db.Customers
where cust.City == "London"
select cust;
foreach (Customer custObj in custQuery)
{
Console.WriteLine("Customer ID: {0}", custObj.CustomerID);
foreach (Order ord in custObj.Orders)
{
Console.WriteLine("\tOrder ID: {0}", ord.OrderID);
foreach (OrderDetail detail in ord.OrderDetails)
{
Console.WriteLine("\t\tProduct ID: {0}", detail.ProductID);
}
}
}
Now i need to ask how can i display Category ID and Category Name of the productID (i am supposing that One product can be in at most one category) by extending the above example
Regards
