API to find out which protobuf message is sent to

Question

What is an API to find out which protobuf message is being sent?

For example, I use the following to get a SendNameMessage object.

SendNameMessage sendNameObj = Serializer.DeserializeWithLengthPrefix <SendNameMessage> (stream, PrefixStyle.Fixed32);

How does the listener know which message is being sent?

Below is my SendNameMessage class:

[ProtoContract]
class SendNameMessage
{
    [ProtoMember(1)]
    public string sendName { get; set; }

    [ProtoMember(2)]
    public int sendId { get; set; }
}

How do I know if a send message is sent sendName or sendId?
