protobuf 的东西，完全整不明白了！急啊！！！！！！！！！！
Dim rpcResponse As New GetPubKey.RpcResponse
rpcResponse = ProtoBuf.Serializer.DeserializeWithLengthPrefix(Of RpcResponse)(Stream, ProtoBuf.PrefixStyle.Base128, Stream.Length)
Console.WriteLine("收到了！" & rpcResponse.flag)／／这里出错＂未将对象引用设置到对象的实例。＂
可是明明是有引用到实例了＂Dim rpcResponse As New GetPubKey.RpcResponse＂
谁能告诉我怎么操作protobuf，进行接口数据传递啊！！！！
[解决办法]
ProtoBuf.Serializer.DeserializeWithLengthPrefix(Of RpcResponse)(Stream, ProtoBuf.PrefixStyle.Base128, Stream.Length)
为 Nothing
[解决办法]
增加：
if rpcResponse is not Nothing then
Console.WriteLine("收到了！" & rpcResponse.flag)
end if
