c# - NHibernate 在 NUnit 和控制台下工作，但在 IIS 下不工作 [throws PropertyAccessException]

Question

我有一个 API，其中包含一个如下所示的对象:

public class NOrgUnit {
    public virtual NOrgUnit Parent { get; set;}
    public virtual ISet<NOrgUnit> children { get; set; } // an Iesi 1.0.1 ISet
    public virtual Int64 Id { get; protected set; }
    public virtual string Name { get; set; }

    // etc.
}

对象有如下映射:

public class NOrgUnitMap : ClassMap<NOrgUnit>
{
    public NOrgUnitMap()
    {
        Id(x => x.Id);

        Map(x => x.Name);

        References(x => x.Parent).Nullable();
        HasMany(x => x.children).AsSet();
    }
}

当我构建我的 API 并在控制台应用程序中引用它时，一切正常。

当我在 asp.net 上下文(特别是 sitecore 项目)中引用相同的 .dll 时，我收到一个 NHibernate 异常:

Org Service encountered unexpected exception [NHibernate.PropertyAccessException: Invalid Cast (check your mapping for property type mismatches); setter of TI.Organization.Core.Impl.DAL.Persistence.Entities.Hierarchy.NOrgUnit ---> System.InvalidCastException: Unable to cast object of type 'TI.Security.Core.Impl.Management.Provisioning.DAL.PersistentGenericSet`1[TI.Organization.Core.Impl.DAL.Persistence.Entities.Hierarchy.NOrgUnit]' to type 'Iesi.Collections.Generic.ISet`1[TI.Organization.Core.Impl.DAL.Persistence.Entities.Hierarchy.NOrgUnit]'.

这几天一直困扰着我。为什么应用程序可以在控制台而不是 IIS 中运行？

Answer 1

TI.Security.Core.Impl.Management.Provisioning.DAL.PersistentGenericSet<T>是一个奇怪的类。这个习俗是开发出来的吗？如果是这样，它可能没有实现 Iesi.Collections.Generic.ISet<T> .如果它确实实现了它，则可能是加载多个 Iesi 程序集的问题。

我从没听说过 sitecore，所以也许它在后台做了一些奇怪的事情。
