 public bool StudentDetail(StudentDetail objstudetail)  
 {  
       StudentDetail studetail = new StudentDetail();  
       studetail.ID = objstudetail.ID;  
       studetail.Name = objstudetail.Name;  
       studetail.Age = objstudetail.Age;  
       studetail.Address = objstudetail.Address;  
       studetail.City = objstudetail.City;  
       try  
       {     
           using (DBEntities context = new DBEntities())  
           {  
                context.studetails.AddObject(studetail);  
                context.SaveChanges();  
           }  
       }  
       catch (Exception ex)  
       {  
        throw ex;
