只是为了找点乐子,我在玩 Last.fm 的 API。他们返回给顶级艺术家的 XML 文件结构如下:
<lfm status="ok">
<topartists user="xbonez" type="overall">
<artist rank="1">
<name>Evanescence</name>
<playcount>4618</playcount>
<mbid>f4a31f0a-51dd-4fa7-986d-3095c40c5ed9</mbid>
<url>http://www.last.fm/music/Evanescence</url>
<streamable>1</streamable>
<image size="small">http://userserve-ak.last.fm/serve/34/48488613.png</image>
<image size="medium">http://userserve-ak.last.fm/serve/64/48488613.png</image>
<image size="large">http://userserve-ak.last.fm/serve/126/48488613.png</image>
<image size="extralarge">http://userserve-ak.last.fm/serve/252/48488613.png</image>
<image size="mega">http://userserve-ak.last.fm/serve/500/48488613/Evanescence++PNG.png</image>
</artist>
</topartists>
</lfm>
这就是我如何去实现它。
我有一个名为 lfmStatus 的类:
[Serializable()]
[XmlRootAttribute("lfm")]
public class lfmStatus
{
[XmlElement("artist")]
public List<Artists> TopArtists { get; set; }
}
还有一类艺术家:
[Serializable()]
public class Artists
{
[XmlElement("name")]
public string Name { get; set; }
[XmlElement("playcount")]
public int playcount { get; set; }
[XmlElement("url")]
public string url { get; set; }
[XmlElement("streamable")]
public int streamable { get; set; }
[XmlElement("image")]
public string image { get; set; }
}
然后我使用这段代码去实现:
string XmlFile = "artists.xml";
XmlSerializer serializer = new XmlSerializer(typeof(lfmStatus));
lfmStatus LoadFile;
using (Stream reader = new FileStream(XmlFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
try
{
Console.WriteLine("Beginning deserialization.");
// Call the Deserialize method to restore the object's state.
LoadFile = (lfmStatus)serializer.Deserialize(reader);
return LoadFile.TopArtists;
}
现在,如果该代码没有包含所有艺术家的 topartists 标记,则该代码非常适用于 XML。但既然它确实如此,我该如何更改我的代码来处理它?我假设我需要添加另一个类。
