proto file:

option java_outer_classname = "Protos";
option optimize_for = SPEED;
message V3DDelta {

repeated V3DDelta v3dDelta = 3;
}
protobuf-net classes:
[ProtoContract]
public class V3DDelta {
[ProtoMember(1)]
public double bid { get; set; }
[ProtoMember(2)]
public int bidSize { get; set; }
[ProtoMember(3)]
public double ask { get; set; }
[ProtoMember(4)]
public int askSize { get; set; }
}
[ProtoContract]
public class Request {
[ProtoMember(1)]
public int Type { get; set; }
[ProtoMember(2)]
public string Rq { get; set; }
}
[ProtoContract]
public class Response {
[ProtoMember(1)]
public int Type { get; set; }
[ProtoMember(2)]
public string Rsp { get; set; }
[ProtoMember(3)]
public List<V3DDelta> v3dDelta { get; set; }
public Response() {
v3dDelta = new List<V3DDelta>();
}
}
When i'm sending message with v3dDeltas (doesn't matter 1 or more) i've got
this:
Invalid wire-type; this usually means you have over-written a file without
truncating or setting the length; see
http://stackoverflow.com/q/2152978/23354
The message is:
9 8 5 26 5 8 233 98 16 1
and is exactly the same on the other side (there's no other bytes in
buffer). I'm reading it that way:
Response rsp = Serializer.DeserializeWithLengthPrefix<Response>(rcvstream,
PrefixStyle.Base128);
(it is encoded using writeDelimitedTo on the java side).
It is right to use List for repeated fields? I tried use array (V3DDelta[])
but exception is the same. When there was no v3dDelta field everything
works great. I'm missing something?
