我正在尝试为正在运行的HQL查询创建DTO对象,但是,当从我的存储库执行我的HQL查询时,它会产生NH强制转换错误:

System.InvalidCastException: Unable to cast object of type 'NHibernate.Hql.Ast.ANTLR.Tree.SqlNode' to type 'NHibernate.Hql.Ast.ANTLR.Tree.FromReferenceNode'.

以前有人遇到过这个吗?

我的DTO映射和课程如下:

    /// <summary>
    /// TODO: Update summary.
    /// </summary>
    public class TaskListItemMapping : ClassMap<TaskListItem>
    {
        public TaskListItemMapping()
        {
            ImportType<TaskListItem>();
            Id(x => x.TaskCode).GeneratedBy.Assigned();
        }
    }




 /// <summary>
    /// A class representing a task list data query result
    /// </summary>
    public class TaskListItem
    {
        public virtual int Code { get; set; }

        public virtual String Client { get; set; }

        public virtual string Matter { get; set; }

        public virtual DateTime DueDate { get; set; }

        public virtual bool Notepad { get; set; }

        public virtual bool Flag { get; set; }

        public virtual string Client { get; set; }

        public virtual string Issue { get; set; }

        public virtual string Grade { get; set; }

        public virtual String TaskInitials { get; set; }

        public virtual string Description { get; set; }

        public TaskListItem()
        {

        }
    }

任何想法都赞赏!

我发现了造成这种情况的原因 - 它与构造函数中的数据不匹配
