一条结合where、group、orderby的linq语法

DataTable dt = (from x in dsResult.Tables[0].AsEnumerable()

where DataTrans.CBoolean(x["IsChecked"]) == true

group x by new

{

no = x.Field<string>("NO"),

ptno = x.Field<string>("PTNO"),

ver = x.Field<int>("VER"),

kd = x.Field<string>("KD"),

que_da = Convert.ToDateTime(x.Field<DateTime>("QUE_DA").ToString("yyyy/MM/dd"))

} into g

orderby g.Key.no,g.Key.ptno,g.Key.ver,g.Key.kd,g.Key.que_da

select new

{

qty = g.Sum(x => Convert.ToInt32(x["QUE_QTY"])),

stock=g.Sum(x=>Convert.ToInt32(x["STOCK"])),

no=g.Key.no ,

ptno=g.Key.ptno,

ver=g.Key.ver,

kd=g.Key.kd,

que_da=g.Key.que_da

}).ConvertDataTable();
