示例1: Northwnd
//引入命名空间
using (Northwnd db = new Northwnd(@"c:\northwnd.mdf"))
{
// Get original Customer from deserialization.
var q1 = db.Orders.First();
string serializedQ = SerializeHelper.Serialize(q1);
var q2 = SerializeHelper.Deserialize(serializedQ, q1);
// Track this object for an update (not insert).
db.Orders.Attach(q2, false);
// Replay the changes.
q2.ShipRegion = "King";
q2.ShipAddress = "1 Microsoft Way";
// DataContext knows how to update the order.
db.SubmitChanges();
}示例2: Northwnd
Customer c = null;
using (Northwnd db = new Northwnd(""))
{
/* Get both the customer c and the customer's order
into the cache. */
c = db.Customers.First();
string sc = c.Orders.First().ShipCity;
}
using (Northwnd nw2 = new Northwnd(""))
{
// Attach customers and update the address.
nw2.Customers.Attach(c, false);
c.Address = "new";
nw2.Log = Console.Out;
/* At SubmitChanges, you will see INSERT requests for all
Customer c’s orders. */
nw2.SubmitChanges();
}示例3: Customer
Customer CustA_File = new Customer();
Customer CustB_File = new Customer();
string xmlFileA = "";
string xmlFileB = "";
// Get the serialized objects.
Customer A = SerializeHelper.Deserialize<Customer>(xmlFileA, CustA_File);
Customer B = SerializeHelper.Deserialize<Customer>(xmlFileB, CustB_File);
List<Order> AOrders = A.Orders.ToList();
using (Northwnd db = new Northwnd(@"c:\northwnd.mdf"))
{
//Attach all the orders belonging to Customer A all at once.
db.Orders.AttachAll(AOrders, false);
// Update the orders belonging to Customer A to show them
// as owned by Customer B.
foreach (Order o in AOrders)
{
o.CustomerID = B.CustomerID;
}
// DataContext can now apply the change of ownership to
// the database.
db.SubmitChanges();
