我如何通过nhibernate获得DTO会员的收藏?

我使用以下语法在项目中检索了集合属性:

public IList<ChildCollectionType> GetChildObjectsByParentId(Int32 id)
{
    ISession session = GetSession();//Get NHibernate session routine
    return session.Load<ParentDTO>(id).ChildCollectionProperty;
}

身份证件

您可以使用自定义转换。

ICriteria selectCriteria = Session.CreateCriteria<DataRun>()
            .SetProjection(Projections.ProjectionList()
                .Add(Projections.Property("SomeCollection"), "Collection"))
            .TransformUsing(new CustomTransformer());

这是您的自定义transformer实现

public class CustomTransformer : IResultTransformer
    {
        public System.Collections.IList TransformList(System.Collections.IList collection)
        {
            return collection;
        }

        public object TransformTuple(object[] tuple, string[] aliases)
        {
            return new MyDto
            {
                //map your data to dto and convert to data type if needed
                YourProperty1 = tuple[0],
                YourProperty12 = (int)tuple[1]
            };
        }
    }
