Linq to sql 查询主体必须以select子句或group子句结尾

错误：在new

中，您忘记了选择

；试试这个：

    var result = from lr in _db.LeaveRequest  
                 join th in _db.TotalHourslu    
                 on lr.TotalHoursEffect 
                 equals th.Minutesselect 
                     new {lr.TotalHoursEffect, th.Minutes, tr.Display};

var result = from lr in _db.LeaveRequest  
             join th in _db.TotalHourslu    
               on lr.TotalHoursEffect equals th.Minutesselect 
             select new {lr.TotalHoursEffect, th.Minutes, tr.Display};
