如何重命名类名通过XML属性? [英] How can I rename class-names via Xml attributes?
问题描述
假设我有一个名为XML序列化类的歌曲
Suppose I have an XML-serializable class called Song:
[Serializable]
class Song
{
public string Artist;
public string SongTitle;
}
为了节省空间(也的半模糊处理的XML文件),我决定重命名XML元素:
In order to save space (and also semi-obfuscate the XML file), I decide to rename the xml elements:
[XmlRoot("g")]
class Song
{
[XmlElement("a")]
public string Artist;
[XmlElement("s")]
public string SongTitle;
}
这样这将产生XML输出:
This will produce XML output like this:
<Song>
<a>Britney Spears</a>
<s>I Did It Again</s>
</Song>
我要重命名/重新映射类的名称/对象为好。再说了,在上面的例子中,我想这个类的歌曲重命名为摹。这样生成的XML应该是这样的:
I want to rename/remap the name of the class/object as well. Say, in the above example, I wish to rename the class Song to g. So that the resultant xml should look like this:
<g>
<a>Britney Spears</a>
<s>I Did It Again</s>
</g>
是否有可能重新命名类名的通过XML的属性
我不希望创建/手动遍历DOM的,所以我在想,如果它可以通过装饰来实现。
I don't wish to create/traverse the DOM manually, so I was wondering if it could be achieved via a decorator.
在此先感谢!
更新:哎呀!这一次,我的真的再次做到了!
忘了说 - 我居然在XML序列化宋对象的列表
UPDATE: Oops! This time I really did it again! Forgot to mention - I'm actually serializing a list of Song objects in the XML.
下面是序列化code:
Here's the serialization code:
public static bool SaveSongs(List<Song> songs)
{
XmlSerializer serializer = new XmlSerializer(typeof(List<Song>));
using (TextWriter textWriter = new StreamWriter("filename"))
{
serializer.Serialize(textWriter, songs);
}
}
和这里的XML输出:
And here's the XML output:
<?xml version="1.0" encoding="utf-8"?>
<ArrayOfSong>
<Song>
<a>Britney Spears</a>
<s>Oops! I Did It Again</s>
</Song>
<Song>
<a>Rihanna</a>
<s>A Girl Like Me</s>
</Song>
</ArrayOfSong>
显然,在 XmlRoot()属性并不在列表上下文重命名的对象。
Apparently, the XmlRoot() attribute doesn't rename the object in a list context.
我缺少的东西吗?
推荐答案
结帐的XmlRoot属性。
Checkout the XmlRoot attribute.
文档可以在这里找到:

[XmlRoot(Namespace = "www.contoso.com",
ElementName = "MyGroupName",
DataType = "string",
IsNullable=true)]
public class Group
更新:
只是尝试,它完美的作品在2008年VS。
这code:
UPDATE: Just tried and it works perfectly on VS 2008. This code:
[XmlRoot(ElementName = "sgr")]
public class SongGroup
{
public SongGroup()
{
this.Songs = new List<Song>();
}
[XmlElement(ElementName = "sgs")]
public List<Song> Songs { get; set; }
}
[XmlRoot(ElementName = "g")]
public class Song
{
[XmlElement("a")]
public string Artist { get; set; }
[XmlElement("s")]
public string SongTitle { get; set; }
}
输出:
<?xml version="1.0" encoding="utf-8"?>
<sgr xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www
.w3.org/2001/XMLSchema">
<sgs>
<a>A1</a>
<s>S1</s>
</sgs>
<sgs>
<a>A2</a>
<s>S2</s>
</sgs>
</sgr>
