EF6 + Linq + RDLC报告

Question

 public IEnumerable GetDataForInvoicePDF(String _ProjectNumber, String _InvoiceNumber)
        {
            var result0 = (from blah in blah blah);

            var result1 =(from blah in blah blah);

            var resultx = (
                            from res0 in result0
                            join res1 in result1
                            on res0.EWONo equals res1.ItNo
                            into temp
                            from res1 in temp.DefaultIfEmpty()
                            select new
                            {
                                EWONo = res0.EWONo ,
                                Stat = res0.Stat,
                                EWOVal = res0.Cost,
                                PctComp = (res0.TInv/ res0.Cost) * 100,
                                PBill =
                                    String.IsNullOrEmpty(res1.ItmInvAmnt.ToString()) ? res0.TInv : (res0.TInv - res1.ItmInvAmnt),
                                NewCharges =
                                    String.IsNullOrEmpty(res1.ItmInvAmnt.ToString()) ? 0 : res1.ItmInvAmnt,
                                AmntRem = res0.Cost - res0.TInv
                            }
                          );
            return resultx;
        }

我想将上述函数的返回数据用作 RDLC报告中 TABLE 的数据源。我已经为rdlc报告的实体框架数据源和使用Linq的数据集做了很多例子，但我很困惑，这些解决方案都没有对我有用。

任何提示将不胜感激，提前致谢！
