IQueryable<v_Search> query = from pd in context.v_Search select pd;
IQueryable<t_HistoricAccountImport> xschistory = from pd in context.t_HistoricAccountImport select pd;
query = query.Where(x => names.Any(y => x.insured_name.Contains(y)));
xschistory = xschistory.Where(xsc => names.Any(y => xsc.insured_name.Contains(y)));
两个实体都存在于同一上下文中
现在,当我尝试下面的代码来组合两个结果时,使用union或concat,这不会发生。
尝试1)
var results = query.concat(xschistory); //Caused error
var result1 = query.union(xschistory); //this also throws error
我还尝试从具有相似数据类型和值的实体中选择列并尝试合并,
尝试2)
var res1 = query.ToList().Select
(x => new
{ x.insured_name ,
x.ReferenceNum
});
var res2 = xschistory.ToList().Select
(y=> new
{
y.insured_name,
y.program_id
});
var finalResults = res1.Union(res2); //Still got Error
无论如何要实现这个目标吗?
答案 0 :(得分:0)
您可以做的一件事就是将它们绑定到
List<v_search> a; List<t_HistoricAccountImport> b;
然后
var together = a.Cast<object>().Concat(b.Cast<object>()).ToList();//cast preferably to something they both inherit from, and is not 'object'.
你现在不能a.concat(b)因为对象的类型不同。
