ASP.Net: Select distinct records using Linq query

Hi

In below linq query i want to get only distinct records by StudentId

public List<View_SessionDeliveryCalendarDetails_Student> GetStudentsByMentor(Int32 MentorId)
{
    List<View_SessionDeliveryCalendarDetails_Student> Result = (from t in context.View_SessionDeliveryCalendarDetails_Students
                                                               where (MentorId != 0 ? t.MentorID == MentorId : 1 == 1)
                                                               select t).ToList();

    return Result;
}

Thanks
