在WP8应用程序中反序列化XML [英] Deserialize XML in a WP8 Application

问题描述

我正在尝试开发Windows Phone 8应用程序(我是wp8开发人员中的新手).

I'm trying to develop a Windows phone 8 app (I'm new in wp8 dev).

我有一个看起来像这样的XML文件:

I have an XML file that look like this:

<?xml version="1.0" ?> 
<root>
   <quotes>
      <quote>
         <author></author>
         <text></text>
         <text></text>
         <text></text>
      </quote>
   </quotes>
</root>

---

这是我的Quotes类:

---

This is my Quotes class:

[XmlRoot("root")]
public class Quotes
{
   [XmlArray("quotes")]
   [XmlArrayItem("quote")]
   public ObservableCollection<Quote> Collection { get; set; }
}

---

这是报价类:

---

This is the quote class:

public class Quote
{
   [XmlElement("author")]
   public string author { get; set; }

   [XmlElement("text")]
   public string text { get; set; }
}

---

然后我使用以下代码对其进行反序列化:

---

Then I use this code to deserialize it:

XmlSerializer serializer = new XmlSerializer(typeof(Quotes));
XDocument document = XDocument.Parse(e.Result);
Quotes quotes = (Quotes) serializer.Deserialize(document.CreateReader());
quotesList.ItemsSource = quotes.Collection;

---

// selected Quote
        Quote quote;

        public QuotePage()
        {
            InitializeComponent();

            // get selected quote from App Class
            var app = App.Current as App;
            quote = app.selectedQuote;

            // show quote details in page
            author.Text = quote.author;
            text.Text = quote.text;

        }  

在具有这种结构的每个Feed中都有一个< text> 部分，该方法可以很好地工作.但是我有很多< text>

This work fine in every feed having this structure with one <text> section. But I have feed with a lot of <text>

如果我在上面使用C#代码，则仅解析第一个< text> 部分，其他部分将被忽略.我需要为单个XML提要中的每个< text> 部分创建单独的List或ObservableCollection.

If I use C# code above, only first <text> section is parsed, others are ignored. I need to create separate List or ObservableCollection for each <text> section in single XML feed.

推荐答案

更改您的 Quote 类以包含 List< string>文字而不是字符串文字:

Change your Quote class to contain List<string> text instead of string text:

public class Quote
{
    [XmlElement("author")]
    public string author { get; set; }

    [XmlElement("text")]
    public List<string> text { get; set; }
}

更新

Update

由于您应用程序中的现有功能和当前的 Quote 类成员，我将保留序列化并使用LINQ to XML将数据从XML加载到 Quotes 类实例中:

Because of existing functionality within your app and current Quote class members I would leave serialization and use LINQ to XML to load data from XML into Quotes class instance:

XDocument document = XDocument.Parse(e.Result);
Quotes quotes = new Quotes() {
    Collection = document.Root
                         .Element("quotes")
                         .Elements("quote")
                         .Select(q => new {
                             xml = q,
                             Author = (string) q.Element("author")
                         })
                         .SelectMany(q => q.xml.Elements("text")
                                           .Select(t => new Quote() {
                                                author = q.Author,
                                                text = (string)t
                                            }))
                         .ToList()
};

我已经用以下 Quotes 和 Quote 类声明对其进行了测试:

I've tested it with following Quotes and Quote class declarations:

public class Quotes
{
    public List<Quote> Collection { get; set; }
}

public class Quote
{
    public string author { get; set; }

    public string text { get; set; }
}

不再需要属性，因为这种方法不使用XmlSerialization.

Attributes are no longer necessary because this approach does not use XmlSerialization.
