XML IList<T> TO DataSet TO DataTable 相互转换

       //遍历XML 获得 DataSet
         //XmlTextReader
          static void Main(string[] args)
         {
             string xmlData = @"D:\study\XMLtest\XMLtest\bin\Debug\bookstore.xml";
             DataSet t = ConvertXMLToDataSet(xmlData);
             Console.WriteLine(t);

         }

         private static DataSet ConvertXMLToDataSet(string xmlFile)
         {
             StringReader stream = null;
             XmlTextReader reader = null;
             try
             {
                 XmlDocument xmld = new XmlDocument();
                 xmld.Load(xmlFile);
                 DataSet xmlDS = new DataSet();
                 stream = new StringReader(xmld.InnerXml);
                 reader = new XmlTextReader(stream);
                 xmlDS.ReadXml(reader);
                 return xmlDS;
                 //DataSet xmlDS = new DataSet();
                 //stream = new StringReader(xmlData);
                 //reader = new XmlTextReader(stream);
                 //xmlDS.ReadXml(reader, XmlReadMode.ReadSchema);
                 //return xmlDS;
             }
             catch (Exception ex)
             {
                 string strTest = ex.Message;
                 return null;
             }
             finally
             {
                 if (reader != null)
                     reader.Close();
             }
         }

如何把 DataSet 转换成 DataTable  *** 注意，我这里的xml文件节点相对混乱，这样读取出来在Dataset中 有三个DataTable 然后怎么把DataTable 怎么给分离开来！

DataSet 转换成 DataTable：

           List<DataTable> lTb = new List<DataTable>();
             for (int i = ; i < tttt.Tables.Count; i++)//主要就是这里的循环
             {
                 lTb.Add(tttt.Tables[i]);
             }

IList<T> 转换成 DataSet

这里的类我改成了 自定义的EMInfo，没用范型

 /// <summary>
         ///  Ilist<T> 转换成 DataSet
         /// </summary>
         /// <param name="list"></param>
         /// <returns></returns>
         public static DataSet ConvertToDataSet(IList<EMInfo> list)
         {
             if (list == null || list.Count <= )
             {
                 return null;
             }

             DataSet ds = new DataSet();
             DataTable dt = new DataTable(typeof(EMInfo).Name);
             DataColumn column;
             DataRow row;

             System.Reflection.PropertyInfo[] myPropertyInfo = typeof(EMInfo).GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance);

             foreach (EMInfo t in list)
             {
                 if (t == null)
                 {
                     continue;
                 }

                 row = dt.NewRow();

                 for (int i = , j = myPropertyInfo.Length; i < j; i++)
                 {
                     System.Reflection.PropertyInfo pi = myPropertyInfo[i];

                     string name = pi.Name;

                     if (dt.Columns[name] == null)
                     {
                         column = new DataColumn(name, typeof(String));
                         dt.Columns.Add(column);
                     }

                     row[name] = pi.GetValue(t, null);
                 }

                 dt.Rows.Add(row);
             }

             ds.Tables.Add(dt);

             return ds;
         }
