Entlib驗證語法只接受數字月份數字？

Question

我有這樣定義一個枚舉：

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

然後屬性驗證定義爲：

<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")> _ 

驗證預期「_＃」，當我刪除TypeConversionValidator，它通過將值設置爲「_3」或枚舉中的任何其他數字。

我需要的僅僅是接受b/t 1-12，並且僅僅在枚舉中使用數字值將不起作用。

任何提示？

謝謝。

UPDATE

我替換爲RangeValidator控件的EnumConversionValidator，並試圖將參數設置爲「1」，但收到以下錯誤：

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

但是那現在給我下面的錯誤：

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

的RangeValidator只能處理原始類型如整數，浮點，雙，小數。因爲您在構造函數中提供了一個整數，所以它試圖將該int與您的枚舉相匹配，因爲VAB使用Object.Compare(object)方法，所以會失敗。

嘗試使用設計，您不必將枚舉範圍定義爲枚舉。嘗試使用簡單的整數字段。更不痛苦。
