本文实例讲述了asp.net使用DataSet的ReadXml读取XML文件及Stream流的方法。分享给大家供大家参考，具体如下：

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(Encoding.Default.GetBytes(strxml));

ds.ReadXml(stream);

GridView1.DataSource = ds;

GridView1.DataBind();

protected void Page_Load(object sender, EventArgs e)

{

  if (!IsPostBack)

  {

    DataSet ds = new DataSet();

    TextReader reader = new StringReader(@"
