添加
      Roche.Models.Logincodes per = new Roche.Models.Logincodes();
                    per.Qrcode = data.Qrcode;
                    per.Count = AdminID;
                    Dd.Logincodes.InsertOnSubmit(per);
                    Dd.SubmitChanges();

 
修改 
using (var db = new RunhuayouModelDataContext())
                    {
                        var amodel = db.admin.Where(b => b.adminid == AdminID).SingleOrDefault();
                        amodel.password = psmodel.NewPassword1;
                        db.SubmitChanges();
                    }


删除
 Dd.ExecuteCommand(string.Format("delete from Brand where id in ({0})", string.Join(",", deleteId))); 建议使用这个
