无法将类型“System.Linq.IQueryable”隐式转换为“string”

[camou_li]

var test =new string[] { from A in CATOS.TB_BERTHPLANS.Include("LOG_SHIP_MOVE") where (A.ATD >= startDate && A.ATD <= endDate) select new { yy = A.VSL_CD + A.CALL_YEAR + A.CALL_SEQ }};
//string[] test =string new[] { from A in CATOS.TB_BERTHPLANS where (A.ATD >= startDate && A.ATD <= endDate) select new { yy = A.VSL_CD + A.CALL_YEAR + A.CALL_SEQ } };

group t by t.SHIP_LOG_NO into tt
select new

var test =(from A in CATOS.TB_BERTHPLANS.Include("LOG_SHIP_MOVE") where (A.ATD >= startDate && A.ATD <= endDate) select new { yy = A.VSL_CD + A.CALL_YEAR + A.CALL_SEQ }).Select(x => x.ToString()).ToArray();

再试试这样 var test =(from A in CATOS.TB_BERTHPLANS.Include("LOG_SHIP_MOVE") where (A.ATD >= startDate && A.ATD <= endDate) select A.VSL_CD + A.CALL_YEAR + A.CALL_SEQ).ToArray();

引用 3 楼 lixipingke 的回复:

var test =(from A in CATOS.TB_BERTHPLANS.Include("LOG_SHIP_MOVE") where (A.ATD >= startDate && A.ATD <= endDate) select new { yy = A.VSL_CD + A.CALL_YEAR + A.CALL_SEQ }).Select(x……

select new 这种是IQueryable的匿名类型。要先转化为string

var test =(from A in CATOS.TB_BERTHPLANS.Include("LOG_SHIP_MOVE") where (A.ATD >= startDate && A.ATD <= endDate) select A.VSL_CD + A.CALL_YEAR + A.CALL_SEQ).ToArray(); 这个数据才正常了，非常感谢版主
