解析XML文档的建议

希望得到一些帮助:我非常感谢开发人员与我分享这个XML文件,因为它应该为我节省很多麻烦。但他告诉我,我要自己去读。基本上,我正在为一款纸牌游戏编写一个windows商店应用程序。我有一个XML,它是我的卡列表,我想把它读入列表。我没有得到任何错误,并且以前已经将XML读取到列表中。如有任何建议,不胜感激。

下面是一段XML代码:

<?xml version="1.0" encoding="UTF-8"?><carddatabase>
    <cards>
        <card>
            <name>Tundra Kavu</name>
            <set picURL="http://gatherer.wizards.com/Handlers/Image.ashx?multiverseid=26805&amp;type=card" picURLHq="" picURLSt="">AP</set>
            <color>R</color>
            <manacost>2R</manacost>
            <type>Creature - Kavu</type>
            <pt>2/2</pt>
            <tablerow>2</tablerow>
            <text>{T}: Target land becomes a Plains or an Island until end of turn.</text>
        </card>
    </cards>
   </carddatabase>

这是我的序列化器:

 public async void readFile()
        {
            StorageFolder myFolder = ApplicationData.Current.LocalFolder;
            StorageFile myFile = await myFolder.CreateFileAsync("cards.xml", CreationCollisionOption.OpenIfExists);
                XmlSerializer Serializer = new XmlSerializer(typeof(List<card>), new XmlRootAttribute("carddatabase"));
                string XmlString = await FileIO.ReadTextAsync(myFile);
                XmlDocument xmlDoc = await XmlDocument.LoadFromFileAsync(myFile);
                var settings = new XmlReaderSettings { ConformanceLevel = ConformanceLevel.Auto, IgnoreWhitespace = true, IgnoreComments = true };
                var stringReader = new StringReader(XmlString);
                XmlReader reader = XmlReader.Create(stringReader, settings);
               List<card> temp = (List<card>)Serializer.Deserialize(reader);
            foreach(card x in temp)
            {
                await tempTable.InsertAsync(x);  
            }
        }

这是我的卡片类:

public class card
{
    public string id { get; set; }
    public string name { get; set; }
    public string manacost { get; set; }
    public string set { get; set; }
    public string color { get; set; }
    public string tablerow { get; set; }
    public string text { get; set; }
    public string type { get; set; }
}

解析XML文档的建议

您可以使用Linq:

解析xml
XDocument xdoc = XDocument.Load(myFile);
var cards = from c in xdoc.Descendants("card")
            select new card() {
                name = (string)c.Element("name"),
                manacost = (string)c.Element("manacost"),
                set = (string)c.Element("set"),
                color = (string)c.Element("color"),
                tableRow = (string)c.Element("tablerow"),
                text = (string)c.Element("text"),
                type = (string)c.Element("type")
            };
foreach(var card in cards)
    await tempTable.InsertAsync(card); 

Linq还允许您将值从字符串转换为其他数据类型,因此您可以在类中拥有属性int TableRow { get; set; },它可以被解析为TableRow = (int)c.Element("tablerow")(或int?,如果不需要tablerow元素)。

在c#中,我们使用CamelCase命名类型和属性。因此,考虑使用如下类型:
public class Card
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string ManaCost { get; set; }
    public string Set { get; set; }
    public string Color { get; set; }
    public int TableRow { get; set; }
    public string Text { get; set; }
    public string Type { get; set; }
}
