Entlib验证语法只接受数字月份数字？

Question

我已经定义了这样的枚举：

Private Enum AllowedMonthNumbers
    _1
    _2
    _3
    _4
    _5
    _6
    _7
    _8
    _9
    _10
    _11
    _12
End Enum

然后将属性验证器定义为：

<TypeConversionValidator(GetType(Int32), MessageTemplate:="Card expiry month must be numeric.", Ruleset:="CreditCard")> _
<EnumConversionValidator(GetType(AllowedMonthNumbers), MessageTemplate:="Card expiry month must be between 1 and 12.", Ruleset:="CreditCard")> _

验证需要“_＃”，因为当我删除TypeConversionValidator时，它会将值设置为“_3”或枚举中的任何其他数字。

我需要的是只接受b / t 1-12，并且只需在枚举中使用数值即可。

任何提示？

感谢。

更新

我用RangeValidator替换了EnumConversionValidator，并尝试将参数设置为“1”，但收到以下错误：

<RangeValidator(1, RangeBoundaryType.Inclusive, 12, RangeBoundaryType.Inclusive, MessageTemplate:="..."> 

然而现在这给了我以下错误：

System.Web.Services.Protocols.SoapException : System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.ArgumentException: Object must be of type Int32.

RangeValidator只能处理原始类型，如int，float，double，decimal。因为你在构造函数中提供了一个整数，所以它试图将那个int与你的枚举匹配，这将失败，因为VAB使用Object.Compare(object)方法。

尝试使用您不必将数字范围定义为枚举的设计。请尝试使用简单的整数字段。痛苦少得多。
