序列化列表包含XML接口

serialization xml c#

Oliver · 技术社区 · 17 年前

我一直在四处阅读,但还没有找到解决我问题的办法

现在,您可能可以看到问题,因为接口无法序列化,因为它们不包含数据。

如何使用一些示例代码编写一个类或序列化器,以获取该对象类型并执行序列化,然后使用正确的类型对对象进行序列化?

一些代码:

  [XmlArray("Actions")]
  public List<IAction> Actions { get; set; }

  public interface IAction
   {
     int ID { get; set; }

     ParameterCollection Parameters { get; set; }

     List<SectionEntity> Validation { get; set; }

     TestResultEntity Result { get; set; }

     string Exception { get; set; }
   }

[XmlType("A")]
public class SimpleActionEntity : IAction
{
    #region IAction Members

    [XmlAttribute("ID")]
    public int ID { get; set; }

    [XmlIgnore]
    public ParameterCollection Parameters { get; set; }

    [XmlIgnore]
    public List<SectionEntity> Validation { get; set; }

    [XmlIgnore]
    public TestResultEntity Result { get; set; }

    [XmlElement("Exception")]
    public string Exception { get; set; }

    #endregion
}

public interface IAction {}
public abstract class ActionBase : IAction {}
public class SimpleAction : ActionBase {}
public class ComplexAction : ActionBase {}


[XmlArray("Actions")]
[XmlArrayItem(typeof(SimpleAction)),XmlArrayItem(typeof(ComplexAction))]
public List<ActionBase> Actions { get; set; }

  [XmlArray("Actions")]
  [XmlArrayItem(typeof(SimpleAction),ElementName = "A")]
  [XmlArrayItem(typeof(ComplexAction),ElementName = "B")]
  public List<ActionBase> Actions { get; set; }

 [XmlArray("Actions")]
 public List<IAction> Actions { get; set; }

我决定创建一个ActionsCollection类来处理List,但也允许我使用IXMLSerialize来覆盖ReadXml和WriteXML方法,这样我就可以处理列表的序列化和反序列化方式。

[XmlElement("Actions")]
public ActionCollection Actions { get; set; }

public class ActionCollection: CollectionBase, IXmlSerializable
{
    #region IList Members
      ...
    #endregion

    #region ICollection Members
     ...
    #endregion

    #region IEnumerable Members
    ...
    #endregion

    #region IXmlSerializable Members

    public System.Xml.Schema.XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(System.Xml.XmlReader reader)
    {
       //TODO
    }

    public void WriteXml(System.Xml.XmlWriter writer)
    {
        foreach (IAction oAction in List)
        {       
                XmlSerializer s = new XmlSerializer(oAction.GetType());
                s.Serialize(writer, oAction);
        }
    }

    #endregion
}

public interface IAction {}
public abstract class ActionBase : IAction {}
public class SimpleAction : ActionBase {}
public class ComplexAction : ActionBase {}

List<IAction> List<ActionBase> .
