.net讀取Rss轉換為DataTable

最近需要用asp.net（c#）接收一個Rss。Rss是自己論壇的數據，而Rss是又在Item中加了一個子項。所以寫了一個通用的讀取Rss的代碼，以後即時再增加或者刪除Items中的子項，此代碼也是可以辨認的。
嗯……貼代碼，記錄一下吧。
復制代碼 代碼如下:
讀取Rss返回DataTable
/// <summary>
        /// 獲Rss並轉換為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)
                {
                    {//為dataTable添加列標識開始
                        XmlNode xnColumn = xnl[0];
                        XmlNodeList columnsNode = xnColumn.ChildNodes;
                        foreach (XmlNode xn in columnsNode)
                        {
                            DataColumn dc = new DataColumn(xn.Name);
                            dt.Columns.Add(dc);
                        }
                    }//為dataTable添加列標識結束

                    {//為DataTable添加行數據
                        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);
                                dr[i] = itemValue.InnerText;
                            }
                            dt.Rows.Add(dr);
                        }
                    }//為DataTable添加列數據
                }
            }
            return dt;
        }
