如何使用C#在ASP.NET 3.5中创建RSS源?
哪些框架组件可以帮助.NET开发人员更轻松地发布RSS或Atom源?
与3.5相比,.NET 4是否有任何额外的功能可以使此任务更加容易?

在3.5中有一个新的命名空间叫做System.ServiceModel.Syndication。
Kevin Miller 对此进行了很好的阐述,使用新的命名空间并不需要太多操作。请查看这篇文章,这里不再赘述,我认为示例代码更容易理解。
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();
}
