使用 .net API 将 FHIR 资源序列化为 JSON答案

【问题标题】：Serialising FHIR Resource to JSON using .net API使用 .net API 将 FHIR 资源序列化为 JSON

【问题描述】：

使用 FHIR .net API (https://github.com/ewoutkramer/fhir-net-api) 我正在尝试解析 XML 文件，然后将其序列化为 JSON。

Bundle inputBundle = FhirParser.ParseBundleFromXml(inputStream);
Console.WriteLine(FhirSerializer.SerializeBundleToJson(inputBundle));

第一行工作正常，我可以看到捆绑包的 XML 文件已被解析并位于“inputBundle”对象中。

但是，当我将其序列化为 JSON（第二行代码）时，出现错误

我使用的 XML 文件直接取自 http://www.hl7.org/implement/standards/fhir/query-example-response.xml.html

有什么想法吗？
