Let’s take a look at the effect first:

First, an ascx page is needed to bind the content of the rss source to a ListView through an XDocument. The code is as follows:

Copy code The code is as follows:

protected void Page_Load(object sender, EventArgs e )
{
// For demo purposes.
System.Threading.Thread.Sleep(1000);

XDocument feedXML =
XDocument.Load("http://feeds .feedsky.com/csdn.net/dujingjing1230");

var feeds = from feed in feedXML.Descendants("item")
select new
{
Title = feed.Element ("title").Value,
Link = feed.Element("link").Value,
Description = feed.Element("description").Value
};

PostList.DataSource = feeds;
PostList.DataBind();
}

Copy code The code is as follows:








  • <%# Eval("Title") %>

    <%# Eval( "Description") %>




  • Next you need to create an aspx page to Display RSS content. Of course, this page uses jQuery's AJAX to get the above data.
    HTML page code:
    RSS Reader code implemented using jQuery's ajax function_jquery
    JS to implement ajax function:
    Copy code The code is as follows :

    $(document).ready(function() {
    $.ajax({
    type: "POST",
    url: "RSSReader.asmx/GetRSSReader" ,
    data: "{}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(msg) {
    $('#RSSContent').removeClass('loading');
    $('#RSSContent').html(msg.d);
    }
    });
    });

    Finally is the content of the web service RSSReader.asmx:
    Copy code The code is as follows:

    public class RSSReader : System.Web.Services.WebService {
    [WebMethod]
    public string GetRSSReader()
    {
    Page page = new Page();
    UserControl ctl =
    (UserControl)page.LoadControl("~/RSSReaderControl.ascx");
    page.Controls.Add(ctl);
    StringWriter writer = new StringWriter();
    HttpContext .Current.Server.Execute(page, writer, false);
    return writer.ToString();
    }
    }

    There is also an image used in the page, here it is No more uploading.
