将类序列化为属性 [英] Serialize Class as attribute

问题描述

我有一个 Point 类，我想将其序列化为属性.这是我真正想要的示例:

I have a Point class which I want to serialize as attribute. Here is the example of what I really want:

public class PointXY
{
    [XmlIgnore]
    public Double X { get; set; }

    [XmlIgnore]
    public Double Y { get; set; }

    public override string ToString()
    {
        return Points;
    }
}

public class TestClass
{
    [XmlAttribute]
    public PointXY Points { get; set; }
}

测试类应该序列化为:

<TestClass Points="0.1 0.2">

</TestClass>

我知道如果使用 IXmlSerializable 接口实现 TestClass，这可以实现.但是我想要 PointsXY 应该将自己作为属性而不是元素发出.是否可以?如果是如何?这也应该被反序列化.

I know this can be achieved if TestClass is implemented using IXmlSerializable interface. But what I want PointsXY should emmit itself as attribute instead of element. Is it possible? If yes how? This should get deserialized as well.

推荐答案

我不知道有什么方法可以将整个类序列化为一个属性.

I don't know of a way to serialize an entire class as an attribute.

您要么必须实现 IXmlSerializable，要么将属性添加到 TestClass 并将那个序列化为一个属性:

You're going to either have to implement IXmlSerializable or add a property to TestClass and serialize that as an attribute:

public class TestClass
{
    [XmlIgnore]
    public PointXY Points { get; set; }

    [XmlAttribute("Points")]
    public string PointString
    {
        get
        {
            return string.Format("{0} {1}",Points.X, Points.Y);
        }
        set
        {
            // TODO:  Add null checking, validation, etc.
            string[] parts = value.Split(' ');
            Points = new PointXY {X = double.Parse(parts[0]), Y = double.Parse(parts[1])};
        }
    }
}
