How can I Identify class with attribute Name?

EmailMessage class

[SomeAttribute("email")]
[DataContract]
public class EmailMessage
{
    [DataMember]
    public int Id { get; set; }

}

Message belongs to Queue Name email. I want to have some attribute of EmailMessage class which can contain queue name. And whenever I will have object I should be able to identify message belongs to which queue and what is its categoryTypeId

Given the following XML:

<?xml version="1.0"?>
<QueueInfos>
<Queue>
    <CategoryTypeId>1</CategoryTypeId>
    <QueueName>email</QueueName>
    <MaxThreadCount>1</MaxThreadCount>
</Queue>

static void main()
{
   var message = new EmailMessage();
}
