c# - WebApi 到 XML 默认访问器的序列化错误

Question

我正在尝试从 WCF 服务做一个 web api，并且多个帖子都正常工作，但是对于特定的一个我有麻烦。这是来自 API 的代码：

[HttpPost]
[DeflateCompression]
[ActionName("Sell")]
public OTA_HotelResNotifRS Sell([FromBody]OTA_HotelResNotifRQ OTA_HotelResNotifRQ)
{
    ClientProviderHotel client = new ClientProviderHotel();
    return client.Hotel_Sell(OTA_HotelResNotifRQ);
}

这是来自 Hotel_Sell 方法的代码：

public OTA_HotelResNotifRS Hotel_Sell(OTA_HotelResNotifRQ Value)
{
    var objBRE = new Engine();


    string MarketCode;


    Timerwatch timerHotel_Sell = new Timerwatch("Hotel_Sell", "");
    timerHotel_Sell.Start();
    ExternalValues External = new ExternalValues();

    XDocument ValueDocument = XDocument.Parse(Serializer.SerializeToString<OTA_HotelResNotifRQ>(Value));

在此刻：

    XDocument ValueDocument = XDocument.Parse(Serializer.SerializeToString<OTA_HotelResNotifRQ>(Value));

我调用以下方法将对象序列化为 XML 字符串：

/// <summary>
/// Serialize Data to XML
/// </summary>
/// <typeparam name="T"> object Base</typeparam>
/// <param name="Value"> Object</param>
/// <returns>Data convert to XML</returns>
public static String SerializeToString<T>(T Value) 
    where T : class
{
   XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
   StringWriter stringWriter = new StringWriter();
   xmlSerializer.Serialize(stringWriter, Value);

   return stringWriter.ToString();
}

但是有以下错误：

System.InvalidOperationException：“生成 XML 文档时出错。”

InvalidOperationException：您必须在 Newtonsoft.Json.Linq.JObject 中实现默认访问器，因为它继承自 ICollection。

如果我使用 WCF 执行该过程，则不会出现错误。

这个过程没有通过 JSON.Net 库进行显式序列化，当我发送 post 请求时，Json 仅在 Postman 中使用
