EnumMemberAttribute.Value Property

By default, the value of an enumeration is the name of the enumeration. When a value is specified, that value will appear in the XML document or stream.

The following code:

[DataContract]
public enum Shapes
{
    [EnumMember]
    Circle,
    [EnumMember]
    Square
}

results in the following XML when serialized with the DataContractSerializer:

<Shapes>Circle</Shapes>

or

<Shapes>Square</Shapes>

The following code, with the Value property set:

[DataContract]
public enum Shapes
{ 

    [EnumMember(Value="1")]
    Circle, 
    [EnumMember(Value="2")]
    Square     
}

results in the following XML:

<Shapes>1</Shapes>

or

<Shapes>2</Shapes>
