Question

我在MVC 4中遇到了上述软件包的问题。即使按下按钮发布数据，验证也不会触发。唯一触发的是DataAnnotationsExtensions命名空间中的那些，只有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下工作正常：

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; } 
    }

下面是我在母版页中设置脚本的设置：

                alert(message); 
            } 
        } 
    </script>

任何帮助都会非常感激......我在这里死了，没有别的地方可以转过来....

Answer 1

最重要的是，以下所有内容都与DataAnnotationExtensions＆amp; ExtensionsDataAnnotations.ClientValidation dlls。

但是，Min＆amp; Maxlength Dataannotations不再适用于MVC4！这让我抓狂！

[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))]

Answer 2

使用正则表达式验证整数，

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

我认为这是解决问题的最简单方法。

package id =“DataAnnotationsExtensions.MVC3”version =“1.1.0.0”targetFramework =“net45”
