与桌子不同

Question

ICriteria crit = session.CreateCriteria<HCOSpendTable>();

foreach (ICriteriaItem<object> param in filters)
{
   crit.Add(Expression.Eq(param.PropertyName, param.FilterValue));
}

crit.SetProjection(Projections.Distinct(Projections.ProjectionList()));

区别不工作。

crit.AddOrder(new Order(sortField, sortOrderAscending));
crit.SetFirstResult(pageNumber * pageSize);
crit.SetMaxResults(pageSize);

transaction.Commit();

return crit.List<IHCOSpendTable>();

Answer 1

您需要将属性映射添加到ProjectionList()

crit.SetProjection(Projections.Distinct(Projections.ProjectionList()
    .Add(Projections.Property("id"), "id")
    .Add(Projections.Property("name"), "name")
));

Answer 2

ICriteria criteria = session.CreateCriteria（typeof（Person））; criteria.SetProjection（Projections.Distinct（Projections.ProjectionList（）。Add（Projections.Alias（Projections.Property（“FirstName”），“FirstName”））。Add（Projections.Alias（Projections.Property（“LastName”）， “名字”））））;

criteria.SetResultTransformer（new NHibernate.Transform.AliasToBeanResultTransformer（typeof（Person）））;

IList people = criteria.List（）;
