如果已经有第三方添加了很酷。我已经在使用DataAnnotationsExtensions，但不提供我正在寻找的内容。

这似乎没有任何参考。所以，希望有人已经解决了这个问题，然后再尝试重新创造轮子，并写下自己的定制验证器。

我已经尝试了Range，但需要2个日期，并且都必须是字符串格式的常量，例如[Range(typeof(DateTime)，“1/1/2011”，“1/1/2016”)]帮助。而DataAnnotationsExtensions Min验证器只接受int和double

更新已解决

感谢@BuildStarted这是我结束了，它的工作伟大的服务器端，现在客户端与我的脚本

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace Web.Models.Validation {

    [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property,AllowMultiple = false,Inherited = true)]
    public sealed class DateMustBeEqualOrGreaterThanCurrentDateValidation : ValidationAttribute,IClientValidatable {

        private const string DefaultErrorMessage = "Date selected {0} must be on or after today";

        public DateMustBeEqualOrGreaterThanCurrentDateValidation()
            : base(DefaultErrorMessage) {
        }

        public override string FormatErrorMessage(string name) {
            return string.Format(DefaultErrorMessage,name);
        }  

        protected override ValidationResult IsValid(object value,ValidationContext validationContext) {
            var dateEntered = (DateTime)value;
            if (dateEntered < DateTime.Today) {
                var message = FormatErrorMessage(dateEntered.ToShortDateString());
                return new ValidationResult(message);
            }
            return null;
        }

        public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata Metadata,ControllerContext context) {
            var rule = new ModelClientCustomDateValidationRule(FormatErrorMessage(Metadata.DisplayName));
            yield return rule;
       }
    }

    public sealed class ModelClientCustomDateValidationRule : ModelClientValidationRule {

        public ModelClientCustomDateValidationRule(string errorMessage) {
            ErrorMessage = errorMessage;
            ValidationType = "datemustbeequalorgreaterthancurrentdate";
        }
    }
}

在我的模特儿

[required]
[DateMustBeEqualOrGreaterThanCurrentDate]
public DateTime SomeDate { get; set; }

客户端脚本

/// <reference path="jquery-1.7.2.js" />

jQuery.validator.addMethod("datemustbeequalorgreaterthancurrentdate",function (value,element,param) {
    var someDate = $("#SomeDate").val();
    var today;
    var currentDate = new Date();
    var year = currentDate.getYear();
    var month = currentDate.getMonth() + 1;  // added +1 because javascript counts month from 0
    var day = currentDate.getDate();
    var hours = currentDate.getHours();
    var minutes = currentDate.getMinutes();
    var seconds = currentDate.getSeconds();

    today = month + '/' + day + '/' + year + '  ' + hours + '.' + minutes + '.' + seconds;

    if (someDate < today) {
        return false;
    }
    return true;
});

jQuery.validator.unobtrusive.adapters.addBool("datemustbeequalorgreaterthancurrentdate");
