c# - 使用 C# 允许在 XML 序列化中重复节点名称

Question

我正在尝试使用 C# 序列化具有重复节点名称的对象，我需要这样做的原因是因为我正在构建一个使用第三方 API 的库。

我需要构建的请求如下所示。

<DATASET>
   <SITE_ID>123</SITE_ID>
   <DATA type=“name”>Secondary List</DATA>
   <DATA type="extra" id="CLICKTHRU_URL">http://my.domain.com/</DATA>
   <DATA type="extra" id="REPLY_FORWARD_EMAIL">support@my.domain.com</DATA>
   <DATA type="extra" id="REPLY_FROM_EMAIL">forward@my.domain.com</DATA>
   <DATA type="extra" id="REPLY_FROM_NAME">8@yahoo.com</DATA>
   <DATA type="extra" id="REPLY_FORWARD_SUBJECT">Customer Replies</DATA>
   <DATA type="extra" id="HANDLE_UNSUBSCRIBE"></DATA>
   <DATA type="extra" id="HANDLE_AUTOREPLY"></DATA>
   <DATA type="extra" id="FOOTER_TEXT">Confidentiality agreement…</DATA>
   <DATA type="extra" id="FOOTER_HTML"> Confidentiality agreement…</DATA>
</DATASET>

我的方法是创建一个表示请求并使用 XML 序列化属性的类，该类如下所示:

[XmlRoot("DataSet")]
public class AddListCallHolder : BaseCallHolder
{
    private BaseAttributeHolder _name = new BaseAttributeHolder(type: "");

    [XmlElement("DATA")]
    public BaseAttributeHolder Name
    {
        get { return _name; }
        set { _name = value; }
    }

    private BaseAttributeHolder _clickthruUrl = new BaseAttributeHolder(id: "CLICKTHRU_URL");

    [XmlElement("DATA")]
    public BaseAttributeHolder CLICKTHRU_URL
    {
        get { return _clickthruUrl; }
        set { _clickthruUrl = value; }
    }
}

属性的基类是:

public class BaseAttributeHolder
{
    [XmlAttribute("type")]
    public string Type { get; set; }

    [XmlAttribute("id")]
    public string Id { get; set; }

    [XmlText]
    public string Value { get; set; }

    public BaseAttributeHolder(string value, string id, string type = "extra")
    {
        Type = type;
        Value = value;
        Id = id;
    }

    public BaseAttributeHolder(string id, string type = "extra")
    {
        Type = type;
        Id = id;
    }

    public BaseAttributeHolder(string type = "extra")
    {
        Type = type;
    }

    public BaseAttributeHolder()
    {

    }
}

当我尝试序列化和反对时，我得到了这个错误:

The XML element 'DATA' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element.

是否有任何解决方法来序列化此对象或获取请求的结构。

使用数组或列表反序列化所有<DATA>怎么样？的，然后添加对该数组进行操作的属性？

  [XmlRoot("DataSet")]
  public class AddListCallHolder
  {
      [XmlArrayItem(typeof(BaseAttributeHolder), ElementName = "DATA")]
      public BaseAttributeHolder[] data 
      { 
           get;
           set;
      }

      [XmlIgnore]
      public BaseAttributeHolder Name
      {
          get
          {
             return data.FirstOrDefault(d => d.Type == "name");
          }
      }

      [XmlIgnore]
      public BaseAttributeHolder CLICKTHRU_URL
      {
          get
          {
             return data.FirstOrDefault(d => d.Type == "extra" && d.Id == "CLICKTHRU_URL");
          }
      }
  }

我想你也能想出二传手。
