一个节点下的不同属性

Question

我有一个对象，我正在使用xml-serializer进行序列化。是否可以实质上插入任意子根节点，并指定属于此根节点的某些属性？

一些属性         public int ID {get;组; }

    public object ActivityType { get; set; }

    public int ObjectId { get; set; }

    public string RelatedObjects { get; set; }

    public string Parameters { get; set; }

    public string Tag { get; set; }

    public List<Condition> Conditions { get; set; }

    public bool OnlySaveIfValid { get; set; }

现在，当我用xml序列化序列化时，我得到：

 <?xml version="1.0" encoding="utf-16"?>
<FNActivity>
  <ID>0</ID>
  <ObjectId>0</ObjectId>
  <Conditions>
   <Condition>
    <Critical>false</Critical>
    <ValidIf>false</ValidIf>
    <IsValid>false</IsValid>
  </Condition>
  <Condition>
    <Critical>false</Critical>
    <ValidIf>false</ValidIf>
    <IsValid>false</IsValid>
    </Condition>
  </Conditions>
 <OnlySaveIfValid>false</OnlySaveIfValid>
</FNActivity>

我想得到的Xml是这样的：

<?xml version="1.0" encoding="utf-16"?>
<FNActivity>
  <ID>0</ID>
  <ObjectId>0</ObjectId>
       **<VALIDATION>
         <Conditions>
           <Condition>
           <Critical>false</Critical>
           <ValidIf>false</ValidIf>
           <IsValid>false</IsValid>
         </Condition>
         <Condition>
          <Critical>false</Critical>
          <ValidIf>false</ValidIf>
          <IsValid>false</IsValid>
         </Condition>
        </Conditions>
        <OnlySaveIfValid>false</OnlySaveIfValid>
      **</VALIDATION>
  </FNActivity>
