我在 ASP.NET MVC3 项目中使用 Fluent NHibernate。我正在编写一个自定义会员提供程序并设置了一个 FNHRoleProvider 类。其中一部分包含以下 try catch 块:
private Entities.Roles GetRole(string rolename)
{
Entities.Roles role = null;
using (ISession session = SessionFactory.OpenSession())
{
using (ITransaction transaction = session.BeginTransaction())
{
try
{
role = session.CreateCriteria(typeof(Entities.Roles))
.Add(NHibernate.Criterion.Restrictions.Eq("RoleName", rolename))
.Add(NHibernate.Criterion.Restrictions.Eq("ApplicationName", this.ApplicationName))
.UniqueResult<Entities.Roles>();
//just to lazy init the collection, otherwise get the error
//NHibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed
IList<Entities.Users> us = role.UsersInRole;
}
catch (Exception e)
{
if (WriteExceptionsToEventLog)
WriteToEventLog(e, "GetRole");
else
throw e;
}
}
}
return role;
}
我收到一条错误消息,指出当前命名空间中不存在 Criterion,尽管我已将 NHibernate.Criterion 添加到我的 using 语句中。我还可以在对象浏览器中查看命名空间的这一部分。
如何解决构建错误?
