Question

return (from s in db.StudentMarks
                where s.Class == Class && s.Year == Year // this line
                orderby s.Year, s.ExamType
                select new StudentAddMarks()
                {
                    --Obj
                 }).ToList();

I am going to return an Object depending on the Class and Year params. I want to remove the where condition when the Class and Year parames are null or zero.

Any ideas please.

Answer 1

This should work:

where (s.Class == Class && s.Year == Year) || Class == null || 
       Class == 0 || Year == null || Year == 0
