Creating an RSS feed in ASP.NET 3.5

How would you create an RSS feed in A开发者_如何学运维SP.NET 3.5 using C#?

What framework pieces would help in making the publishing of an RSS or Atom feed easier for the .NET developer?

Are there any extra features in .NET 4 to make this task easier than in 3.5?

There's a new namespace for this in 3.5 called System.ServiceModel.Syndication.

Kevin Miller has a great writeup on this, not a whole lot too it with the new namespace, check out the article, no need to repost here, example code is much easier to look at in my opinion.

public void BindData()
{                    

    StringWriter sw = new StringWriter();
    XmlTextWriter writer = new XmlTextWriter(sw);
    XmlDocument doc = new XmlDocument();
    XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);

    writer.WriteStartElement("feed");
    writer.WriteAttributeString("xmlns", "http://www.w3.org/2005/Atom");
    writer.WriteString("\n");
    writer.WriteElementString("title", this.TTT + " - " + this.Title);
    writer.WriteString("\n");


    writer.WriteStartElement("link");
    writer.WriteAttributeString("href", this.Url );
    writer.WriteEndElement();

    writer.WriteElementString("id", "urn:uuid:" + Guid.NewGuid().ToString());            
    writer.WriteElementString("updated", DateTime.UtcNow.ToString("o"));


    foreach (var  item in this.lista)
    {
        writer.WriteStartElement("entry");
        writer.WriteElementString("title", item.Value.Title);

        writer.WriteStartElement("link");
        writer.WriteAttributeString("href", item.Key);
        writer.WriteEndElement();

        writer.WriteElementString("id", item.Key);
        string slikaImgUrl = item.Value.Imaga;

        if (string.IsNullOrEmpty(slikaImgUrl) == false)
        {
            writer.WriteStartElement("link");
            writer.WriteAttributeString("rel", "enclosure");
            writer.WriteAttributeString("type", "image/jpeg");
            writer.WriteAttributeString("href", slikaImgUrl);
            writer.WriteEndElement();
        }

        writer.WriteStartElement("author");
        writer.WriteElementString("name", this.Title);
        writer.WriteEndElement();

        writer.WriteStartElement("summary");
        writer.WriteAttributeString("type", "text");
        writer.WriteCData(" ");
        writer.WriteEndElement();               

        writer.WriteElementString("updated", DateTime.UtcNow.ToString("o"));
        writer.WriteElementString("published", DateTime.UtcNow.ToString("o"));
        writer.WriteEndElement();
        writer.WriteString("\n");                
    }

    writer.WriteEndElement();
    string dataOut = sw.ToString();


    Response.Clear();
    Response.ContentType = "text/xml";

    Response.Write(dataOut);
    writer.Close();
    Response.End();
}
