            bool phoneCheck2 = Regex.IsMatch(phone, @"^[1]+[9][1,8,9]+d{8}");
            if (!phoneCheck && !phoneCheck2 || phoneLength != 11)
            {
                return false;    //    手机号不合法
            }
            return true;    //    手机号合法
        }

还有验证身份证、邮箱等的合法性,这里就不贴出来了,有需要的联系我。

实现对数据库的增删改查

//增加和修改
            if (isEdit == false)//新增保存
            {
                ProjectTable temp = new ProjectTable();
                ControlsDataToModel(temp);
              
                try
                {
                    myLog.WriteStartLog("新增项目信息", sender);

                    int isAddNew = new ProjectTableBLL().AddNew(temp);
                    MessageBox.Show("新增成功!");

//查询
 if (txtCheckByXM_MC.EditValue == null)
