读取Rss返回DataTable
/// <summary>
        /// 获Rss并转换为DataTable返回
        /// </summary>
        /// <param name="filePath">Rss地址</param>
        /// <returns></returns>
         public static DataTable GetRss(string filePath)
        {
            DataTable dt=new DataTable();
            WebClient wc=new WebClient();
            Stream srContent=wc.OpenRead(filePath);

            StreamReader sr=new StreamReader(srContent);
            if (!sr.EndOfStream)
            {
                XmlDocument xmlDoc=new XmlDocument();
                xmlDoc.Load(sr);
                XmlNodeList xnl=xmlDoc.SelectNodes("rss/channel/item");
                if (xnl.Count > 0)
                {
                    {//为dataTable添加列标识开始
                        XmlNode xnColumn=xnl[0];
                        XmlNodeList columnsNode=xnColumn.ChildNodes;
                        foreach (XmlNode xn in columnsNode)
                        {
                            DataColumn dc=new DataColumn(xn.Name);
                            dt.Columns.Add(dc);
                        }
                    }//为dataTable添加列标识结束

                    {//为DataTable添加行数据
                        foreach (XmlNode xnDate in xnl)
                        {
                            DataRow dr=dt.NewRow();
                            for (int i=0; i < dt.Columns.Count; i++)
                            {
                                XmlNode itemValue=xnDate.SelectSingleNode(dt.Columns[i].ColumnName);
