asp.net使用DataSet的ReadXml读取XML文件及Stream流的方法
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：
stringstrxml="<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>"; DataSetds=newDataSet(); Streamstream=newMemoryStream(Encoding.Default.GetBytes(strxml)); ds.ReadXml(stream); GridView1.DataSource=ds; GridView1.DataBind();
protectedvoidPage_Load(objectsender,EventArgse)
{
if(!IsPostBack)
{
DataSetds=newDataSet();
TextReaderreader=newStringReader(@"
