Question

我有以下protobuf文件，我想使用“ protobuf-gen”将它们编译为C＃。我发现“ chassis.proto”可以成功，但是“ perception_lane.proto”却不能。我想原因是“ common.Header”，应该是“ apollo.common.Header”：

我用C ++编译了bazel，但他们没有这个问题。可以使用协议将Aslo编译为python。问题是protobuf本身是否支持此用法？还是“ protobuf-net”无法识别这种用法？

header.proto

syntax = "proto2";

package apollo.common;

import "modules/common/proto/error_code.proto";

message Header {

  optional double timestamp_sec = 1;
  ...
}

chassis.proto

syntax = "proto2";

package apollo.canbus;

import "modules/common/proto/header.proto";

message Chassis {
  optional apollo.common.Header header = 19;
}

perception_lane.proto

syntax = "proto2";

package apollo.perception;

import "modules/common/proto/header.proto";


message PerceptionLanes {
    optional common.Header header = 1;
}

我收到以下错误消息：

这听起来像是protobuf-net.Reflection中名称解析的错误；最好登录具有足够信息以重现它的GitHub（最好是最少的信息！）。甚至更好：您可以分叉，修复和PR：）

作为解决方法，您可以尝试在架构中使用完全限定的名称（以.开头）。例如，Empty是.google.protobuf.Empty IIRC。

使用时可以省略“ protobuf软件包”吗？
