我看到了问题，但是在哪里，什么类型？任何建议如何找到它？

我尝试搜索 Dictionary< List< 并查看里面的内容，但没有成功。

InnerException 是 null

我试过拨打 ProtoBuf.Meta.RuntimeTypeModel.Default.GetSchema(typeof(LinkBudgetScenario)); 相同的无用消息。

是否可以获得更有用的错误消息而不是内部无用的调试消息？

Answer 1

解决问题的步骤：

尝试查看源对象。（如果运气不好goto 2）
将 Protobuf-net 源代码带到你的解决方案中（如果运气不好 goto 3）
安装.net reflector并开启调试功能，不要忘记停止所有异常（Debug -> Windows -> Exception Settings）。现在您可以确定问题类型了。

Answer 2

步骤：

更新到 protobuf-net 2.3.0：https://www.nuget.org/packages/protobuf-net/2.3.0
重新运行您的代码并阅读消息
