C#实现的Check Password和锁定输错密码锁定账户

C#实现的Check Password，并根据输错密码的次数分情况锁定账户：如果输入错误3次，登录账户锁定5分钟并提示X点X分后重试登录。如果5分钟后再次输入，累计输入错误密码累计达到5次。则账户会被永久锁定，需联系系统管理员进行把数据库中的输入错误的次数（errorcount）进行清零解锁才能登陆。实现代码如下：

 public  class UserInfo1
    {
        public string Error_count { get; set; }
        public string Error_time { get; set; }
    }

            execRes = new ExecutionResult();

            if (strs.Length < 2)
            {
                execRes.Status = false;
                execRes.Message = "无效的账号。";
            }
            else

根据登录不同的网域进行Form验证
