        }
      }
    ]
  }
}

这是一个约会结构：

当我尝试将其反序列化为 FHIR Appointment 类时，尝试失败：

Appointment a = JsonConvert.DeserializeObject<Appointment>(strAppt, jss);

也不例外，但显然，这并没有成功：

Appointment 类已实例化，但其所有属性均为 null 或 0

以下是我已合并到我的项目中的 FHIR 包：

【解决方案1】：

解决方法不是使用JsonConvert，而是使用专门的FhirJsonParser。

这行得通：

FhirJsonParser fjp = new FhirJsonParser();
Bundle bundle = fjp.Parse<Bundle>(Response);
foreach (var entry in bundle.Entry)
{
    Appointment appt = (Appointment)entry.Resource;
}
