【问题描述】：

是否可以从protobuf-net 获得更详细的错误信息？

我发现Channelizer 有问题，但它是一个庞大的类，我检查了好几次。

是否可以打开调试日志或任何有助于发现问题的东西？

【问题讨论】：

  • 您可以通过ProtoBuf.Meta.RuntimeTypeModel.Default.GetSchema(typeof(Channelizer))) 查看为您的类型生成的架构，也许您会发现问题。正如here 所述，Protobuf-net 没有实现调试跟踪。
  • 这意味着 [ProtoInclude] 指定了无法找到的内容。有什么代码可以看这里吗？
  • @MarcGravell 请查看更新后的问题
  • @dbc GetSchema(typeof(Chan‌nelizer)) 没有返回太多，只有Unable to resolve sub-type of: AE.DataModel.IssueStore，所以它说有问题，不多:(
  • @GSerjo 如果您不使用typeof，那么您需要使用程序集限定 名称（AQN，在Type 上可用）。或者，如果你想做一些定制的事情，IIRC 有一个内置的类型解析器 API，但我不记得我脑海中的细节。如果 AQN 方法不起作用，请大声告诉我。

【解决方案1】：

正如@MarcGravell 在评论中所说“如果您不使用 typeof，那么您需要使用程序集限定名称（AQN，在 Type 上可用）。”

所以，尝试使用

  1. typeof，如果不可能的话goto 2

  2. 使用程序集限定名，可以从typeof(int).Type获取

顺便说一句：请确保您使用的是最新版本。 protobuf-net 2.3.0 是调试友好的版本
