How to get the type of packet received? about protobuf-csharp-port HOT 3 CLOSED

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)

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.)
