使用.NET讀取Rss數據，并轉換為DataTable返回。方法很簡單，看一下面的代碼吧。

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，以后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。

代碼如下:

讀取Rss返回DataTable

/// <summary>

        /// 獲Rss并轉換為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;

        }
