可序列化类继承自具有自己类型的属性的接口

.. 即使有单子。

(其实这不好玩…)

public class Root
{
    [XmlElementAttribute("ClassA", typeof(ClassA))]
    [XmlElementAttribute("ClassB", typeof(ClassB))]
    [XmlElementAttribute("ClassC", typeof(ClassC))]
    public List<IMyInterface> Items { get; set; }
}


public abstract class IMyInterface
{
    IMyInterface Parent { get; set; }
    string Name { get; set; }
}

public interface IMyInterface
{
    [XmlElement(Type=typeof(App.Projekt), ElementName="Projekt")]
    [XmlElement(Type=typeof(App.Person), ElementName="Person")]
    [XmlElement(Type=typeof(App.Task), ElementName="Task")]
    IMyInterface parent
    {
        get;
        set;
    }
}

编辑:我用这个代码测试了这个问题。没用。我想,xmlement将与“object”类型的属性执行相同的操作。

public interface IMyInterface
{
    IMyInterface Parent { get; set; }
    string Name { get; set; }
}

public class ClassA : IMyInterface
{
    [XmlElement(Type = typeof(ClassA), ElementName = "ClassA")]
    [XmlElement(Type = typeof(ClassB), ElementName = "ClassB")]
    [XmlElement(Type = typeof(ClassC), ElementName = "ClassC")]
    public IMyInterface Parent { get; set; }
    public string Name { get; set; }

    public string AProperty { get; set; }
}

public class ClassB : IMyInterface
{
    [XmlElement(Type = typeof(ClassA), ElementName = "ClassA")]
    [XmlElement(Type = typeof(ClassB), ElementName = "ClassB")]
    [XmlElement(Type = typeof(ClassC), ElementName = "ClassC")]
    public IMyInterface Parent { get; set; }
    public string Name { get; set; }

    public string BProperty { get; set; }
}

public class ClassC : IMyInterface
{
    [XmlElement(Type = typeof(ClassA), ElementName = "ClassA")]
    [XmlElement(Type = typeof(ClassB), ElementName = "ClassB")]
    [XmlElement(Type = typeof(ClassC), ElementName = "ClassC")]
    public IMyInterface Parent { get; set; }
    public string Name { get; set; }

    public string CProperty { get; set; }
}

“无法序列化成员 TestXMLSerializer.ClassA.Parent属于 类型TestXMLSerializer.IMyInterface 因为它是一个接口。”
