解决.Net MVC 中出现 非介入式客户端验证规则中的验证类型名称必须唯一。下列验证类型出现重复: required 的bug

最近在开动科技创新作品的开发，出现了一个让人很烦恼的错误，每次从浏览页跳转到编辑页时就会出现一下错误

非介入式客户端验证规则中的验证类型名称必须唯一。下列验证类型出现重复: required

上一下出错的代码

model

 public partial class td_students
    {

        [StringLength()]
        [Key]
        [HiddenInput(DisplayValue = false)]
        public string Id { get; set; }

        [Required]
        [StringLength()]
        [Display(Name = "学号")]
        public string school_code { get; set; }

        [Required]
        [StringLength()]
        [Display(Name = "姓名")]
        public string student_name { get; set; }

        [StringLength()]
        [Display(Name = "年级")]
        public string grade { get; set; }

        [StringLength()]
        [Display(Name = "院系")]
        public string dept { get; set; }

        [StringLength()]
        [Display(Name = "专业")]
        public string major { get; set; }

        [StringLength()]
        [Display(Name = "班级")]
        public string banji { get; set; }

        [StringLength()]
        [Display(Name = "性别")]
        public string gender { get; set; }

        [StringLength()]
        [Display(Name = "民族")]
        public string nation { get; set; }

        [Display(Name = "出生日期")]
        public DateTime? born_date { get; set; }

        [StringLength()]
        [Display(Name = "手机号码")]
        public string telephone { get; set; }

        [StringLength()]
        [Display(Name = "政治面貌")]
        public string politicstatus { get; set; }

        [StringLength()]
        [Display(Name = "身份证号码")]
        public string ID_card { get; set; }

        [StringLength()]
        [Display(Name = "户籍")]
        public string native_place { get; set; }

        [StringLength()]
        [Display(Name = "家庭住址")]
        public string address { get; set; }

        [StringLength()]
        [Display(Name = "家庭联系电话")]
        public string home_telephone { get; set; }

        [Display(Name = "入学时间")]
        public DateTime? rollin_date { get; set; }

        [StringLength()]
        [Display(Name = "宿舍")]
        public string dormitory { get; set; }

        [StringLength()]
        [Display(Name = "照片")]
        public string imageurl { get; set; }

        public bool? audit { get; set; }

        [Column("lock")]
        public bool? _lock { get; set; }
    }

前端代码：

 @using (Html.BeginForm("Edit", "Student", FormMethod.Post, new { enctype = "mutipart/form-data", @class="form-inline" }))
    {
        <div class="panel-body">
            @Html.Hidden("studentId", Model.Id)
            @foreach (var property in ViewData.ModelMetadata.Properties)
            {
                switch (property.PropertyName)
                {
                    case "Id":
                    case "audit":
                    case "_lock":
                    case "imageUrl":
                        break;
                    default:
                        <div class="form-group">
                            <label>@(property.DisplayName ?? property.PropertyName)</label>//这里就抛出异常
                            @Html.TextBox(property.PropertyName, null, new { @class = "form-control form-inline input-sm" })
                            @Html.ValidationMessage(property.PropertyName)
                        </div>
                        break;
                }
            }

        </div>
    }

国内搜索引擎搜索不到任何相关的解决方案 使用google搜索，终于StackOverflow的在不起眼的小角落里找到了解决办法

翻译过来就是因为引入了Ninject.MVC3这个包，出现了注入验证，卸载Ninject重装之后就解决了问题

我的项目中也使用了Ninject来做依赖注入  安装的是Ninject.MVC5这个包 卸载重装之后搞定

真的是揪心啊

这里说一句，遇到问题国内搜索引擎搞不定，就去StackOverflow.com 一般都可以找到解决方案
