            var byteArray = Encoding.ASCII.GetBytes(information.Surname + Environment.NewLine + information.DOBP + Environment.NewLine + information.Email + Environment.NewLine + information.Gender + Environment.NewLine + information.Tel);
            var stream = new MemoryStream(byteArray);

        }
        if (buttonType=="Validate")

        }
        return View(information);



    }

Answer 1

您可以使用 Javascript 执行相同操作。检查链接链接以进行 javascript 检查。检查值后，您可以在浏览器本身中进行验证。为什么要在后面的代码中执行此类操作？是否需要此类活动来执行后面的代码？

Here is a code example I am using some where in m code. Hope it helps you.

public bool IsValidDOB(DateTime date)
    {
        bool  objResult = null;
        try
        {
            if ( date < System.DateTime.Now )
            {
                DateTime now = DateTime.Today;
                int age = now.Year - date.Year;
                if (date > now.AddYears(-age)) age--;
                if (age>=18)
                objResult =  true;
                else
                    objResult =  false;
            }
            else
            {
                objResult =  false;
            }
        }
        catch (Exception ex)
        {
            objResult = new  false;
            Core.Logger.AdminTrace.Logger(Core.Logger.LogArea.BusinessTier, ex);
        }
        return objResult;
    }
