使用重復元素反序列化XML

Question

這是VS2012中的C＃，針對.NET 4.5構建

我是XML序列化/反序列化的新手，並試圖弄清楚這一點。 我有XML

<?xml version="1.0"?>
<AvailabilityResponse>
  <ApiKey>LZ6c@3O9#tq*BAyX4KGYBsCgZ*HpUDtrB*XI*WGLw</ApiKey>
  <ResellerId>101</ResellerId>
  <SupplierId>1004</SupplierId>
  <ForeignReference>1234567890</ForeignReference>
  <Timestamp>2015-08-06T05:20:49.000Z</Timestamp>
  <RequestStatus>
      <Status>SUCCESS</Status>
  </RequestStatus>
  <TTAsku>dcnt</TTAsku>
  <TourAvailability>
      <TourDate>2015-08-31</TourDate>
      <TourOptions>
          <DepartureTime>07:30 PM</DepartureTime>
      </TourOptions>
      <AvailabilityStatus>
          <Status>AVAILABLE</Status>
      </AvailabilityStatus>
  </TourAvailability>
  <TourAvailability>
      <TourDate>2015-08-31</TourDate>
      <TourOptions>
          <DepartureTime>08:30 PM</DepartureTime>
      </TourOptions>
      <AvailabilityStatus>
          <Status>AVAILABLE</Status>
      </AvailabilityStatus>
  </TourAvailability>
</AvailabilityResponse>

我正在嘗試反序列化為此類結構：

[Serializable]
public class AvailabilityResponse
{
    public string ApiKey { get; set; }
    public string ResellerId { get; set; }
    public string SupplierId { get; set; }
    public string ForeignReference { get; set; }
    public DateTime Timestamp { get; set; }
    public RequestStatus RequestStatus { get; set; }
    public string TTAsku { get; set; }
    public TourAvailability[] TourAvailability { get; set; }
}

[Serializable]
public class RequestStatus
{
    public string Status { get; set; }
}

[Serializable]
public class TourAvailability
{
    public DateTime TourDate { get; set; }
    public TourOptions TourOptions { get; set; }
    public AvailabilityStatus AvailabilityStatus { get; set; }
}
[Serializable]
public class AvailabilityStatus
{
    public string Status { get; set; }
    public string UnavailabilityReason { get; set; }
}

我這樣做是：

public static AvailabilityResponse DeserializeAvailabilityResponse(Stream replyStream)
{
    XmlSerializer xmlSr = null;
    XmlReader inreader = null;

    if (replyStream != null)
    {
        XmlTextReader xmlreader = new XmlTextReader(replyStream);
        XmlDocument respXml = new XmlDocument();
        respXml.Load(xmlreader);
        xmlreader.Close();

        xmlSr = DeserializeXmlDoc(respXml, out inreader, typeof(AvailabilityResponse));
    }

    if (xmlSr != null && inreader != null)
    {
        AvailabilityResponse inventory = (AvailabilityResponse)xmlSr.Deserialize(inreader);
        return inventory;
    }
    return null;
}

問題是，當我檢查退回的庫存物品時， TourAvailability如下所示：

例如，我希望它像RequestStatus一樣，用[+]允許我打開它並查看每個元素。 即使我陳述錯了，我也希望至少有一個TourAvailability，而不是零。

我可能在這里錯過了幾件事，但是您能提供的任何幫助將不勝感激。 我還有很多這類事情要處理，因為我們公司的方向稍有改變。

Answer 1

只需使用[XmlElement("TourAvailability")]屬性，即可看到數組的元素。

public class AvailabilityResponse
{
    public string ApiKey { get; set; }
    public string ResellerId { get; set; }
    public string SupplierId { get; set; }
    public string ForeignReference { get; set; }
    public DateTime Timestamp { get; set; }
    public RequestStatus RequestStatus { get; set; }
    public string TTAsku { get; set; }
    [XmlElement("TourAvailability")]
    public TourAvailability[] TourAvailability { get; set; }
}

順便說一句：您不需要那些[Serializable]屬性

PS：反序列化代碼可以簡化為：

using (var f = File.OpenRead(filename))
{
    XmlSerializer ser = new XmlSerializer(typeof(AvailabilityResponse));
    var resp = (AvailabilityResponse)ser.Deserialize();
}

嘗試這個

            Stream stream = File.Open(FILENAME, FileMode.Open);
            AvailabilityResponse availabilityResponse = DeserializeAvailabilityResponse(stream);
        }
        public static AvailabilityResponse DeserializeAvailabilityResponse(Stream replyStream)
