一个简单的后台验证程序（注册流程常用）
//在前台中，也有一些使用了已经封装后的验证（验证码验证），它自己封装了提交（form）方法。

在UserInfoBLL中实现验证方法 Two_yanzheng() : //作用是判断数据在数据库中是否存在，而后，在前台页面中 做 XXX 已存在的 验证提示！
//-------------------------------验证手机号和邮箱号是否已存在---------------------------------------// public static string Two_yanzheng(string RequestText) { string result = ""; using (UserPersonalBLL bll = new UserPersonalBLL()) { UserPersonal UserPhone = bll.FindALL().Where(x => x.FPhone == RequestText).FirstOrDefault(); UserPersonal UserEmail = bll.FindALL().Where(x => x.FMail == RequestText).FirstOrDefault(); if (UserPhone == null && UserEmail == null) //&& UserEmail == null { result = "0"; } else { result = "1"; } } return result; }
有些梦想是遥不可及的，除非你坚持！
