NHibernate(无法定位类)

本文关键字：定位 NHibernate | 更新日期: 2023-09-27 18:21:49

我有下一个代码：

IUnitOfWork factory = DI.Get<IUnitOfWork>();
ISession session = (ISession)ReflectionUtils.GetPropertyValue(factory, "Session");
IQuery query = session.CreateQuery("SELECT new Model.TestClass(FechaCreacion,Demora) from Pedido");
TestClass[] _list = query.List<TestClass>().ToArray();
public class TestClass
{
    public DateTime FechaCreacion { get; set; }
    public int Demora { get; set; }
}

我需要返回一个对象列表，以便在数据网格视图中显示它们，但我得到了下一个异常：

NHibernate.QueryException was unhandled
  Message=Unable to locate class [Model.TestClass] [SELECT new Model.TestClass(FechaCreacion,Demora) from Pedido]
  Source=NHibernate
  QueryString=SELECT new Model.TestClass(FechaCreacion,Demora) from Pedido

如果有人能帮我，我将不胜感激，很抱歉我的英语很差。

NHibernate(无法定位类)

您可以尝试在您的hbm文件中添加这样的内容：

<import class="NH.Domain.DTOs.ProductDTO, NH.Domain" />
