Retrieve enum value based on XmlEnumAttribute name value
- by CletusLoomis
I need a Generic function to retrieve the name or value of an enum based on the XmlEnumAttribute "Name" property of the enum. For example I have the following enum defined:
Public Enum Currency
<XmlEnum("00")> CDN = 1
<XmlEnum("01")> USA= 2
<XmlEnum("02")> EUR= 3
<XmlEnum("03")> JPN= 4
End Enum
The first Currency enum value is 1; the enum name is "CDN"; and the XMLEnumAttribute Name property value is "00".
If I have the enum value, I can retrieve the XmlEnumAttribute "Name" value using the following generic function:
Public Function GetXmlAttrNameFromEnumValue(Of T)(ByVal pEnumVal As T) As String
Dim type As Type = pEnumVal.GetType
Dim info As FieldInfo = type.GetField([Enum].GetName(GetType(T), pEnumVal))
Dim att As XmlEnumAttribute = CType(info.GetCustomAttributes(GetType(XmlEnumAttribute), False)(0), XmlEnumAttribute) 'If there is an xmlattribute defined, return the name
Return att.Name
End Function
So using the above function, I can specify the Currency enum type, pass a value of 1, and the return value will be "00".
What I need is a function to perform if the opposite. If I have the XmlEnumAttribute Name value "00", I need a function to return a Currency enum with a value of 1. Just as useful would be a function that would return the enum name "CDN". I could then simply parse this to get the enum value.
Any assistance would be appreciated.
