ASP.NET MVC 学习笔记 (3)

学习NerdDinner 时，InsertOnSubmit方法执行后怎么也插入不到数据库中，查找MSDN,找到了原因，原来还要执行一下SubmitChanges方法。

// Create a new Order object.
 Order ord = new Order
{
    OrderID = 12000,
    ShipCity = "Seattle",
    OrderDate = DateTime.Now
    // …
 };

 // Add the new object to the Orders collection.
 db.Orders.InsertOnSubmit(ord);

 // Submit the change to the database.
 try
{
    db.SubmitChanges();
}
catch (Exception e)
{
    Console.WriteLine(e);
    // Make some adjustments.
    // ...
    // Try again.
    db.SubmitChanges();
}
