EnumMemberAttribute Class
Specifies that the field is an enumeration member and should be serialized.
Assembly: System.Runtime.Serialization (in System.Runtime.Serialization.dll)
The EnumMemberAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
![]() | Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
![]() ![]() | _Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
![]() ![]() | _Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
![]() ![]() | _Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
The EnumMemberAttribute enables fine control of the names of the enumerations as they are serialized.
To use EnumMemberAttribute, create an enumeration and apply the DataContractAttribute attribute to the enumeration. Then apply the EnumMemberAttribute attribute to each member that needs to be in the serialization stream.
The following example shows EnumMemberAttribute applied to members of an enumeration.
<DataContract()> _ Public Enum Position <EnumMember(Value:="Emp")> Employee <EnumMember(Value:="Mgr")> Manager <EnumMember(Value:="Ctr")> Contractor NotASerializableEnumeration End Enum <DataContract()> _ Public Class Person Implements IExtensibleDataObject Public Sub New(ByVal firstNameValue As String, _ ByVal lastNameValue As String) LastName = firstNameValue FirstName = lastNameValue End Sub Private extensioDataValue As ExtensionDataObject Public Property ExtensionData() As ExtensionDataObject _ Implements IExtensibleDataObject.ExtensionData Get Return extensioDataValue End Get Set extensioDataValue = value End Set End Property <DataMember()> _ Friend FirstName As String <DataMember()> _ Friend LastName As String <DataMember()> _ Friend Description As Position End Class NotInheritable Public Class Test Private Sub New() End Sub Shared Sub Main() WriteObject("Enum.xml") Console.ReadLine() End Sub Shared Sub WriteObject(ByVal path As String) Console.WriteLine("Writing...") Dim p As New Person("Denise", "Smith") p.Description = Position.Manager Dim fs As New FileStream(path, FileMode.Create) Try Dim ser As New DataContractSerializer(GetType(Person)) ser.WriteObject(fs, p) Console.WriteLine("Done") Catch exc As SerializationException Console.WriteLine(exc.Message) Console.WriteLine(exc.StackTrace) Finally fs.Close() End Try End Sub End Class
