（一）添加数据：
public void AddUser(User user)
{
ISession session = NhibernateFactory.GetInstance().GetSession();
session.Save(user);
session.Flush();
}
执行，报错“当 IDENTITY_INSERT 设置为 OFF 时，不能为表中的标识列插入显式值”
把 User.hbm.xml文件中：
《generator》节点class 改为 "native":
<hibernate-mapping xmlns ="urn:nhibernate-mapping-2.2"
assembly="UserInformation.Domin"
namespace="UserInformation.Domin.Entities">
<class name="UserInformation.Domin.Entities.User,UserInformation.Domin"
table="UserInformation" >
<id name="Id"
type="Int32"
unsaved-value="null">
<generator class="native"></generator>
</id>
<property name="Name"></property>
<property name="PassWord"></property>
<property name="UserType"></property>
</class> </hibernate-mapping>
（二）修改数据：
/// <summary>
/// 修改：
/// </summary>
/// <param name="id"></param>
public void ModifyUser(int id)
{
ISession session = NhibernateFactory.GetInstance().GetSession();
if (AllUser == null)
{
AllUser = GetUserList();
}
var result = AllUser.FirstOrDefault(x => x.Id == id);
session.Update(result);
} public void ModifyUser(User user)
{
ISession session = NhibernateFactory.GetInstance().GetSession();
session.Update(user);
session.Flush();
}
测试修改：
[TestMethod]
public void ModifyUserTest()
{
UserData userData = new UserData();
var result = userData.GetUserList();
var updatedUser = result.FirstOrDefault(x => x.Id == );
updatedUser.Name = "改过以后的名称";
userData.ModifyUser(updatedUser);
}
（三） 删除：
public void DeleteUser(int id)
{
ISession session = NhibernateFactory.GetInstance().GetSession();
if (AllUser == null)
{
AllUser = GetUserList();
}
var result = AllUser.FirstOrDefault(x => x.Id == id);
session.Delete(result);
session.Flush();
} public void DeleteUser(User user)
{
ISession session = NhibernateFactory.GetInstance().GetSession();
session.Delete(user);
session.Flush();
}
删除测试：
[TestMethod]
public void DeleteUserTest()
{
UserData userData = new UserData();
var result = userData.GetUserList();
var updatedUser = result.FirstOrDefault(x => x.Id == );
userData.DeleteUser(updatedUser);
}
执行可运行
