Validation Entlib验证语法是否只接受数字月数？

我已将枚举定义为：

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

然后，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")> _

---

RangeValidator

只能处理int、float、double、decimal等基本类型。因为您在构造函数中提供了一个整数，所以它试图将该整数与枚举匹配，这将失败，因为VAB使用

Object.Compare（Object）

方法

尝试使用不必将数字范围定义为枚举的设计。请尝试改用简单的整数字段。痛苦要小得多

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

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