本文實例講述了asp.net使用DataSet的ReadXml讀取XML文件及Stream流的方法。分享給大家供大家參考，具體如下：
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(@"
