XML TO DataSet TO DataTable 相互转换

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：

1           List<DataTable> lTb = new List<DataTable>();
2             for (int i = 0; i < tttt.Tables.Count; i++)//主要就是这里的循环
3             {
4                 lTb.Add(tttt.Tables[i]);
5             }
