asp.net-mvc - MVC3 jquery 验证 MinLength 过滤器不起作用

Question

我在我的模式中有这个:

[Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Registration), ErrorMessageResourceName = "NameRequired")]
[MinLength(3, ErrorMessageResourceType = typeof(Registration), ErrorMessageResourceName = "NameTooShort")]
public String Name { get; set; }

这最终在:

    <div class="editor-label">
        <label for="Name">Name</label>
    </div>
    <div class="editor-field">
        <input class="text-box single-line" data-val="true" data-val-required="Name is required" id="Name" name="Name" type="text" value="" />
        <span class="field-validation-valid" data-valmsg-for="Name" data-valmsg-replace="true"></span>
    </div>

为什么 MinLength 被编译器忽略了？我怎样才能“打开它”？

Answer 1

而不是使用 MinLength 属性改用这个:

[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]

String Length MSDN

优点:无需编写自定义属性
