[英]Multiple Saves in NHibernate (2.1)
How can I save a collection of objects in NHibernate? 如何在NHibernate中保存对象集合? I'm migration from SubSonic (I don't like SubSonic 3 version and SubSonic 2 is dead...) and this used to be a simple operation...
我正在从SubSonic迁移(我不喜欢SubSonic 3版本,SubSonic 2已经死了...),这以前是一个简单的操作...
There is a way to map a collection(without associations) to complete this task? 有没有办法映射一个集合(没有关联)来完成此任务?
My actual code is: 我的实际代码是:
using (ISession session = NHibernateHelper.GetCurrentSession())
{
using (ITransaction transaction = session.BeginTransaction())
{
foreach (var player in players)
{
session.Save(player);
transaction.Commit();
}
}
}

这是编辑后的版本:
using (ISession session = NHibernateHelper.GetCurrentSession())
{
using (ITransaction transaction = session.BeginTransaction())
{
foreach (var player in players)
{
session.Save(player);
}
transaction.Commit();
}
}
