How to use DataSet's ReadXml to read XML files and Stream streams

This article describes the method of using DataSet's ReadXml to read XML files and Stream streams. Share it for your reference, as follows:

string strxml = "<xml><m><a>1</a><b>2</b></m><m><a>11</a><b>22</b></m><m><a>111</a><b>222</b></m></xml>";
DataSet ds = new DataSet();
Stream stream = new MemoryStream((strxml));
(stream);
 = ds;
();

protected void Page_Load(object sender, EventArgs e)
{
  if (!IsPostBack)
  {
    DataSet ds = new DataSet();
    TextReader reader = new StringReader(@"
