生成rss的基本c#代码

//从收录数据库中取出内容生成不同的rss，mycon中的数据表中至少应包括title、description、link、pubDate、author字段


public void DB2rss(OleDbConnection mycon,string XmlFile)






{


XmlTextWriter objX = new XmlTextWriter(Server.MapPath(XmlFile), System.Text.Encoding.GetEncoding("GB2312"));




objX.Formatting = Formatting.Indented;




objX.WriteStartDocument();




objX.WriteStartElement("rss");


objX.WriteAttributeString("version", "2.0");


objX.WriteStartElement("channel");


objX.WriteElementString("title", "肉香鱼丝的rss");


objX.WriteElementString("description", "肉香鱼丝收集整理的有用的东东。");


objX.WriteElementString("copyright", "Copyright (C) 2007 肉香鱼丝");


objX.WriteElementString("ttl", "5");//rss更新时间


objX.WriteElementString("pubDate", DateTime.Now.ToString());


string strCom = "*****";//*****代表具体的SQL语句，select出title、description、link、pubDate、author


OleDbCommand myCommand = new OleDbCommand( strCom , mycon ) ;


OleDbDataReader dr=myCommand.ExecuteReader();


while(dr.Read())






{


objX.WriteStartElement("item");


objX.WriteElementString("title", dr.GetString(0));


objX.WriteElementString("description", dr.GetString(1));


objX.WriteElementString("link", dr.GetString(2));


objX.WriteElementString("pubDate",dr.GetDateTime(3).ToString());


objX.WriteElementString("author", dr.GetString(4));


objX.WriteEndElement();


}


dr.Close();


objX.WriteEndElement();


objX.WriteEndElement();


objX.WriteEndDocument();


objX.Flush();


objX.Close();


}
