EnumMemberAttribute Class

Specifies that the field is an enumeration member and should be serialized.

Namespace:  System.Runtime.Serialization
Assembly:  System.Runtime.Serialization (in System.Runtime.Serialization.dll)

[AttributeUsageAttribute(AttributeTargets.Field, Inherited = false, AllowMultiple = false)]
public sealed class EnumMemberAttribute : 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
}

[DataContract]
public class Person : IExtensibleDataObject
{
    public Person(string firstNameValue, string lastNameValue)
    {
        LastName = firstNameValue;
        FirstName = lastNameValue;
    }

    private ExtensionDataObject extensioDataValue;
    public ExtensionDataObject ExtensionData
    {
        get { return extensioDataValue; }
        set { extensioDataValue = value; }
    }

    [DataMember]
    internal string FirstName;
    [DataMember]
    internal string LastName;
    [DataMember]
    internal Position Description;
}

public sealed class Test
{
    private Test() { }
    static void Main()
    {

        try
        {

            Test t = new Test();
            t.Serialize("Enum.xml");
            Console.WriteLine("Done");
            Console.ReadLine();
        }
        catch (SerializationException  exc)
        {
            Console.WriteLine(exc.Message);
            Console.ReadLine();

        }

    }



    private void Serialize(string path)
    {
        Console.WriteLine("Serializing...");
        Person p = new Person("Denise", "Smith");
        p.Description = Position.Manager;

        FileStream fs = new FileStream(path, FileMode.Create);

        try
        {
            DataContractSerializer ser =
                new DataContractSerializer(typeof(Person));
            ser.WriteObject(fs, p);
            Console.WriteLine("Done");
        }
        catch (SerializationException exc)
        {
            Console.WriteLine(exc.Message);
            Console.WriteLine(exc.StackTrace);
        }
        finally
        {
            fs.Close();
        }
    }
}
