ProtoBuf-net Deserialize does not work

问题

code is here:

        var responseMsg = new ResponseMessage()
        {
            code = ErrorCode.OK,
            type = MsgType.LOGIN,
            responseStr = "this is local server"
        };
        var serverStream = new MemoryStream();
        ProtoBuf.Serializer.Serialize(serverStream, responseMsg);
        Console.WriteLine($"responseMsg {responseMsg?.responseStr ?? "failed"}\n");

        var response =ProtoBuf.Serializer.Deserialize<ResponseMessage>(serverStream);
        Console.WriteLine($"response {response?.responseStr ?? "failed"}\n");

result is

responseMsg this is local server

response 

ProtoBuf-net can not Deserialize what it Serialized. it's really a strange thing

回答1:

You need to rewind the stream to the beginning by resetting its Position before you can read from it:

serverStream.Position = 0;
var response = ProtoBuf.Serializer.Deserialize<ResponseMessage>(serverStream);

Sample fiddle.
