序列化/反序列化枚举作为元素名称（而不是元素内容/值）

I need to deserialize/serialize XML which looks like this:

我需要反序列化/序列化XML,如下所示:

<color>
    <green/>
</color>

where <green/> may be <red/>, <blue/> etc. - very large (but limited) set.

其中 可以是 , 等 - 非常大(但有限)设置。

I'd like to describe it as simple enum in my code:

我想在我的代码中将其描述为简单的枚举:

enum ColorName
{
    [XmlEnum("red")]
    Red,
    [XmlEnum("green")]
    Green,
    [XmlEnum("blue")]
    Blue,

    ...
    etc.
}

But, if I write my object model like this:

但是,如果我像这样写我的对象模型:

class Color
{
    [XmlElement("name")]
    public ColorName ColorName;
}

class Something
{
    [XmlElement("color")]
    public Color Color;
}

enum gets into XML as a value, rather than element name:

枚举作为值而不是元素名称进入XML:

<color>
    <name>green</name>
</color>

Is there any way to get enum value written into XML element name (see the first XML snippet - that's the goal), rather than XML element value, without having to re-type all the values (it's a very large set) as empty class names, or resorting to custom serialization (I would like to avoid it, because serialized class contains a lot of other members, which are perfectly serialized by default)?

是否有任何方法可以将枚举值写入XML元素名称(请参阅第一个XML片段 - 这是目标),而不是XML元素值,而不必将所有值(它是一个非常大的集合)重新键入为空类名称,或诉诸自定义序列化(我想避免它,因为序列化的类包含很多其他成员,默认情况下完全序列化)?

(I can't change the schema, it's third-party).

(我不能改变架构,它是第三方)。

No, this is not supported by simply decorading your classes with [Xml*] attributes. You will have to implement IXmlSerializable on Something and do it yourself. Note that in most cases you don't have to bother with the GetSchema method; implementing ReadXml and WriteXml is just fine.

不,只需使用[Xml *]属性解析您的类就不支持此功能。你必须在Something上实现IXmlSerializable并自己动手。请注意,在大多数情况下,您不必费心使用GetSchema方法;实现ReadXml和WriteXml就好了。
