I'm afraid you haven't provided nearly enough information about what you're
trying to do, what kind of packet you're talking about etc. *Much* more
information is needed if we're going to be able to help you.

I'm sorry for so poor description.
After a complete message data received by socket that is byte array serialized
from a proto class,the trouble is how to get the type of the data.So that the
next step it is and be deserialized into a relevant class object similar to
xxx.ParseFrom(byte[] data)

from protobuf-csharp-port.
If you've just put a serialized message on, with no other descriptor, then you
can't get the type... it's not part of the serialized form. If it could be one
of multiple types, you should create a *wrapper* type which is effectively a
discriminated union (see the "techniques" page in the main protobuf wiki).
Deserialize to *that* message (because it'll always be that) and then you can
detect which submessage to fetch.
(This isn't a defect in protobuf-csharp-port, it's just a Protocol Buffer
technique you need to know about.)
