Rangos de Anotación de Datos de Fechas

Hice esto para solucionar su problema

 public class DateAttribute : RangeAttribute
   {
      public DateAttribute()
        : base(typeof(DateTime), DateTime.Now.AddYears(-20).ToShortDateString(),     DateTime.Now.AddYears(2).ToShortDateString()) { } 
   }

La validación de jQuery no funciona con [Range (typeof (DateTime), "date1", " date2"] -- Mi documento de MSDN es incorrecto

Para esas ocurrencias raras cuando se ve obligado a escribir una fecha como una cadena (cuando se usan atributos), recomiendo encarecidamente usar la notación ISO-8601. Eso elimina cualquier confusión en cuanto a si el 01/02/2004 es el 2 de enero o el 1 de febrero.

[Range(typeof(DateTime), "2004-12-01", "2004-12-31",
    ErrorMessage = "Value for {0} must be between {1} and {2}")]
public datetime Something { get; set;}

Aquí hay otra solución.

[Required(ErrorMessage = "Date Of Birth is Required")]
[DataType(DataType.Date, ErrorMessage ="Invalid Date Format")]
[Remote("IsValidDateOfBirth", "Validation", HttpMethod = "POST", ErrorMessage = "Please provide a valid date of birth.")]
[Display(Name ="Date of Birth")]
public DateTime DOB{ get; set; }

Simplemente cree un nuevo controlador MVC llamado ValidationController y pase este código allí. Lo bueno del enfoque "Remoto" es que puede aprovechar este marco para manejar cualquier tipo de validaciones basadas en su lógica personalizada.

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.Mvc;

namespace YOURNAMESPACEHERE
{
    public class ValidationController : Controller
    {
        [HttpPost]
        public JsonResult IsValidDateOfBirth(string dob)
        {
            var min = DateTime.Now.AddYears(-21);
            var max = DateTime.Now.AddYears(-110);
            var msg = string.Format("Please enter a value between {0:MM/dd/yyyy} and {1:MM/dd/yyyy}", max,min );
            try
            {
                var date = DateTime.Parse(dob);
                if(date > min || date < max)
                    return Json(msg);
                else
                    return Json(true);
            }
            catch (Exception)
            {
                return Json(msg);
            }
        }
    }
}

Utilizo este enfoque:

[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)]
internal sealed class DateRangeAttribute : ValidationAttribute
{
    public DateTime Minimum { get; }
    public DateTime Maximum { get; }

    public DateRangeAttribute(string minimum = null, string maximum = null, string format = null)
    {
        format = format ?? @"yyyy-MM-dd'T'HH:mm:ss.FFFK"; //iso8601

        Minimum = minimum == null ? DateTime.MinValue : DateTime.ParseExact(minimum, new[] { format }, CultureInfo.InvariantCulture, DateTimeStyles.None); //0 invariantculture
        Maximum = maximum == null ? DateTime.MaxValue : DateTime.ParseExact(maximum, new[] { format }, CultureInfo.InvariantCulture, DateTimeStyles.None); //0 invariantculture

        if (Minimum > Maximum)
            throw new InvalidOperationException($"Specified max-date '{maximum}' is less than the specified min-date '{minimum}'");
    }
    //0 the sole reason for employing this custom validator instead of the mere rangevalidator is that we wanted to apply invariantculture to the parsing instead of
    //  using currentculture like the range attribute does    this is immensely important in order for us to be able to dodge nasty hiccups in production environments

    public override bool IsValid(object value)
    {
        if (value == null) //0 null
            return true;

        var s = value as string;
        if (s != null && string.IsNullOrEmpty(s)) //0 null
            return true;

        var min = (IComparable)Minimum;
        var max = (IComparable)Maximum;
        return min.CompareTo(value) <= 0 && max.CompareTo(value) >= 0;
    }
    //0 null values should be handled with the required attribute

    public override string FormatErrorMessage(string name) => string.Format(CultureInfo.CurrentCulture, ErrorMessageString, name, Minimum, Maximum);
}

Y úsalo así:

[DateRange("2004-12-01", "2004-12-2", "yyyy-M-d")]
ErrorMessage = "Value for {0} must be between {1} and {2}")]
