我在 MVC 4 中遇到上述包的问题。即使按下按钮发布数据后验证也不会触发。唯一触发的是来自 DataAnnotationsExtensions 命名空间的那些，其中仅在我尝试提交数据后才包含 Required 和 Email 属性。

下面是我用于 LogOnModel 的代码，它在 MVC 3 下运行良好：

public class LogOnModel 
    { 
        [Required(ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "Required")] 
        [StringLength(50, ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "MinLength6")] 
        [Display(Name = "Username", ResourceType = typeof(YeagerTechResources.Resources))] 
        public string UserName { get; set; } 

        [Required(ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "Required")] 
        [DataType(DataType.EmailAddress)] 
        [Email(ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "Email")] 
        public string Email { get; set; } 

        [Required(ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "Required")] 
        [StringLength(50, ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "MinLength6")] 
        [DataType(DataType.Password)] 
        [Display(Name = "Password4", ResourceType = typeof(YeagerTechResources.Resources))] 
        public string Password { get; set; } 

        [Display(Name = "AcctRemember", ResourceType = typeof(YeagerTechResources.Resources))] 
        public bool RememberMe { get; set; } 
    }

这是作者的网站：http ://weblogs.asp.net/srkirkland/archive/2011/02/23/introducing-data-annotations-extensions.aspx 以及他对另一个使用它们的人的回复（日期为 2012 年 8 月 10 日) “我已经测试了当前的 NuGet 包可以在 MVC4 中正常工作，同时使用 .NET 4.0 和 4.5。”

下面是我在母版页中对脚本的设置：

<head>

                alert(message); 
            } 
        } 
    </script> 
</head>

任何帮助将不胜感激......我死在水里，没有其他地方可以转身......

底线是以下所有内容都适用于 DataAnnotationExtensions & ExtensionsDataAnnotations.ClientValidation dll。

但是，Min & Maxlength Dataannotations 在 MVC4 中不再起作用！它快把我逼疯了！

[Required(ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "Required")]
         [StringLength(50, ErrorMessageResourceType = typeof(YeagerTechResources.Resources), ErrorMessageResourceName = "MinMaxLength", MinimumLength = 6)]
         //[StringLength(10, MinimumLength = 2)]
         //[Range(1, 100)]
         //[Min(3)]
         //[MinLength(2, ErrorMessage = "Name must be more than 5 characters")]
         //[MaxLength(5, ErrorMessage = "Name must be more than 5 characters")]
         [Display(Name = "Username", ResourceType = typeof(YeagerTechResources.Resources))]

使用正则表达式来验证整数，

[RegularExpression("^[0-9]*$", ErrorMessage = "The number must be an integer")]
public int Number {get; set;}

我确实认为这是解决问题的最简单方法。
