JsonConvert.SerializeObject 正在返回一个空对象
我可以序列化一个通用对象，我可以在不同的程序集中序列化这个对象。我已经验证了这些属性是公开的，并且还用 json 标记明确标记。Newtonsoft.Json 没有抛出异常。相关版本 Newtonsoft.Json 12.0.2，通过 nuget 安装。
测试失败，因为预期调用和实际调用不同。实际调用（未粘贴）是我所期望的，但 Json 序列化在测试中给出了一个空对象。
logger.Verify(m => m.LogUsage(JsonConvert.SerializeObject(_svc), "AddService", string.Empty, false), Times.Once());
更新：我尝试添加以下测试，它仍然序列化为一个空对象，尽管 _svc 被正确定义（我可以通过设置断点并检查它来判断。）
