C＃XML Serializer - 使用相同的元素名称序列化多个节点

Question

我正在尝试生成以下XML：

<Tags>
   <Tag name="Motor" path="_types_" type="UDT_DEF">
      <Property name="Value"/>
      <Property name="DataType">2</Property>
      <Parameters>
      </Parameters>
      <Tag name="Alm" path="" type="Folder"/>
      <Tag name="Sts" path="" type="Folder"/>
      <Tag name="Comm" path="Alm" type="OPC">
         <Property name="Value"/>
         <Property name="DataType">6</Property>
         <Property name="OPCServer">Tag Server</Property>
         <Property name="OPCItemPath">ns=1;s=Alm.Comm</Property>
         <Alarms>
            <Alarm name="Alarm">
               <Property name="setpointA">1.0</Property>
            </Alarm>
         </Alarms>
      </Tag>
      <Tag name="Current" path="Sts" type="OPC">
         <Property name="Value"/>
         <Property name="DataType">6</Property>
         <Property name="OPCServer">Tag Server</Property>
         <Property name="OPCItemPath">ns=1;s=Sts.Current</Property>
      </Tag>
   </Tag>
</Tags>   

我设置了类，所以我有一个包含Tag的标签类，我也有Alarms等的类。它序列化很好，直到我得到标签元素“Comm”，然后它抛出一个错误：

  

类型'System.InvalidOperationException'的未处理异常   发生在System.Xml.dll中   附加信息：出现错误   反映类型'TagData.Tags'

当我有多个具有相同名称但子元素不同的元素时，如何将我的类序列化为XML？我的想法是自己处理序列化，但我认为有更好，更简单的解决方案。

这是我的C＃课程：

/// <summary>
/// Contains all the tags.
/// </summary>       
public class Tags
{
    [XmlElement("Tags")]
    public List<Tag> ignTagList { get; set; }
}


/// <summary>
/// The tag itself.
/// </summary>
[Serializable()]
public class Tag
{
    [XmlAttribute("type")]
    public string Type;
    [XmlAttribute("path")]
    public string Path;
    [XmlAttribute("name")]
    public string Name;
    [XmlElement("Property")]
    public List<Property> props { get; set; }

    [XmlElement("Tag")]
    public List<Folder> folders { get; set; }

    [XmlElement("Tag")]  // #### ERROR OCCURS HERE.  IF I RENAME THIS IT WILL SERIALIZE!! ####
    public List<OPCTag> opcTags { get; set; }

    public Tag()
    {
        this.props = new List<Property>();
        this.folders = new List<Folder>();
        this.opcTags = new List<OPCTag>();
    }

    public Tag(string Type, string Path, string Name)
    {
        this.props = new List<Property>();
        this.folders = new List<Folder>();
        this.opcTags = new List<OPCTag>();
        this.Type = Type;
        this.Path = Path;
        this.Name = Name;
    }

}


/// <summary>
/// Property data structure.
/// </summary>
[Serializable()]
public class Property
{
    [XmlAttribute("name")]
    public string Name;
    [XmlText]
    public string DataTypeValue;

    public Property()
    {
    }

    public Property(string Name, string DataTypeValue)
    {
        this.Name = Name;
        this.DataTypeValue = DataTypeValue;
    }

}


/// <summary>
/// Folder data structure.
/// </summary>
[Serializable()]
public class Folder
{
    [XmlAttribute("type")]
    public string Type;
    [XmlAttribute("path")]
    public string Path;
    [XmlAttribute("name")]
    public string Name;

    public Folder()
    {
    }

    public Folder(string Type, string Path, string Name)
    {
        this.Type = Type;
        this.Path = Path;
        this.Name = Name;
    }

    public Folder(string Path, string Name)
    {
        this.Type = "Folder";
        this.Path = Path;
        this.Name = Name;
    }

}


/// <summary>
/// OPC tag data structure.
/// </summary>
[Serializable()]
public class OPCTag
{
    [XmlAttribute("type")]
    public string Type;
    [XmlAttribute("path")]
    public string Path;
    [XmlAttribute("name")]
    public string Name;
    [XmlIgnore]
    public IgnDataType DataType;
    [XmlElement("Property")]
    public List<Property> props { get; set; }

    public OPCTag()
    {
        this.props = new List<Property>();
    }

    public OPCTag(string Type, string Path, string Name)
    {          
        this.Type = Type;
        this.Path = Path;
        this.Name = Name;
        this.props = new List<Property>();
    }

    public OPCTag(string Path, string Name, UDTDataType DataType)
    {
        this.Type = "OPC";
        this.Path = Path;
        this.Name = Name;
        this.props = new List<Property>();
        this.props.Add(new Property("Value", ""));
        this.props.Add(new Property("DataType", ((int)DataType).ToString()));
    }

}
