LINQ to Entities无法识别方法Int32 get_Item(Int32)

Question

我是关于实体框架和linq的新手.我的查询是这样的

var query = (from d in db.MYTABLE
             where d.RELID.Equals(myInts[0])
             select d.ID).Distinct();

List<int?> urunidleri = query.ToList();

当我执行此代码时,我收到错误消息"LINQ to Entities无法识别方法Int32 get_Item(Int32)".我怎样才能解决我的问题？

谢谢...

Answer 1

您需要将您存储int在变量中,以便EntityFramework不会尝试将整个数组拉入其范围.

var myInt = myInts[0];

var query = (from d in db.MYTABLE
             where d.RELID.Equals(myInt)
             select d.ID).Distinct();

List<int?> urunidleri = query.ToList();

Answer 2

var firstInt = myInts[0];
var query = (from d in db.MYTABLE
             where d.RELID.Equals(firstInt)
             select d.ID).Distinct();

List<int?> urunidleri = query.ToList();
