Silverlight读取xml

Silverlight读取xml2011-09-23 cnblogs nasa这例子是为我的试验项目"SLShowCase"做的读取xml的试验.看到园子里的朋友做到仿163幻灯片的demo 就提前发上来了.

项目的功能是做案例展示.

ok 首先,先定义xml.

projects.xml
<？xml version="1.0" encoding="utf-8" ？ >
<projects>
 <project id="1" title="nasa.wang @ cnblogs" category="web" hit="23" createdate="2008-4-9" converpic="null" iscommend="true" votenum="8" score="10">
 </project>
</projects>

在sl中定义类.

public class project
  {
    public int id { get; set; }
     public string title { get; set; }
    public string category { get; set; }
     public int hit { get; set; }
    public DateTime createdate { get; set; }
     public string converpic { get; set; }
    public bool iscommend { get; set; }
     public int votenum { get; set; }
    public int score { get; set; }
     //public IList<pitem> pitems { get; set; }
    //public IList<pcomment> pcomments { get; set; }
  }

使用WebClient来加载数据.linq来格式化数据.

public Page（）
    {
      InitializeComponent（）;
       WebClient client = new WebClient（）;
      client.DownloadStringAsync（new Uri （HtmlPage.Document.DocumentUri, "projects.xml"））;
       client.DownloadStringCompleted += new DownloadStringCompletedEventHandler （client_DownloadStringCompleted）;
    }

void client_DownloadStringCompleted（object sender, DownloadStringCompletedEventArgs e）
    {
      XmlReader reader = XmlReader.Create（new StringReader （e.Result））;
      XDocument document = XDocument.Load（reader）;
      var projects = from f in document.Descendants（"project"）
              select new project
              {
                id = int.Parse（f.Attribute（"id"）.Value）,
                title = f.Attribute （"title"）.Value,
                category = f.Attribute （"category"）.Value,
                hit = int.Parse（f.Attribute （"hit"）.Value）,
                createdate = DateTime.Parse（f.Attribute （"createdate"）.Value）,
                converpic = f.Attribute （"converpic"）.Value,
                iscommend = bool.Parse（f.Attribute （"iscommend"）.Value）,
                votenum = int.Parse（f.Attribute （"votenum"）.Value）,
                score = int.Parse（f.Attribute （"score"）.Value）,
              };
      List<project> _projects = new List<project>（）;
      _projects.AddRange（projects）;
       txtStatus.Text ="read success for " + _projects[0].title;
    }

读取完毕. ;）
