方法一：使用xml控件 <% @ page language="c#"%>

方法一：使用xml控件
<% @ page language="c#"%>
<html>
<body>
       <h3><font face="verdana">读取xml方法一</font></h3>
       <from runat=server>
        <asp:xml id="xml1" documentsource="grade.xml" runat="server" />
      </from>
</body>
</html>
方法二：使用dom技术
<% @ page language="c#"%>
<% @ import namespace="system.xml"%>
<% @ import namespace="system.xml.xsl"%>
<html>
<script language="c#" runat="server">
void page_load(object sender,eventargs e)
{
   xmldocument doc=new xmldocument();
   doc.load(server.mappath("grade.xml"));
   xml1.document=doc;
}
</script>
<body>
   <h3><font face="verdana">读取xml方法二</font></h3>
    <from runat=server>
        <asp:xml id="xml1"  runat="server" />
    </from>
</body>
</html>
方法三：使用dataset对象
<% @ page language="c#"%>
<% @ import namespace="system.data"%>
<% @ import namespace="system.data.oledb"%>
<script language="c#" runat="server">
void page_load(object sender,eventargs e)
{
   dataset  objdataset=new dataset();
   objdataset.readxml(server.mappath("grade.xml"));
   dgemployees.datasource=objdataset.tables["student"].defaultview;
   dgemployees.databind();
}
</script>
<body>
   <h3><font face="verdana">读取xml方法三</font></h3>
   <asp:datagrid id="dgemployees" runat="server" />
</body>
</html>
方法四：按文本方式读取
<% @ page language="c#"%>
<% @ import namespace="system.xml"%>
<html>
<script language="c#" runat="server">
private void page_load(object sender,eventargs e)
{
    xmltextreader objxmlreader=new xmltextreader(server.mappath("grade.xml"));
    string strnoderesult="";
    xmlnodetype objnodetype;
while(objxmlreader.read())
{
    objnodetype =objxmlreader.nodetype;
    swith(objnodetype)
    {
    case xmlnodetype.xmldeclaration:
      //读取xml文件头
      strnoderesult+="xml declaration:<b>"+objxmlreader.name+""+objxmlreader.value+"</b><br/>";
      break;
   case xmlnodetype.element:
     //读取标签
     strnoderesult+="element:<b>"+objxmlreader.name+"</b><br/>";
     break;
   case xmlnodetype.text:
     //读取值
     strnoderesult+=" -value:<b>"+objxmlreader.value+"</b><br/>";
     break;
   }
//判断该节点是否有属性
if(objxmlreader.attributecount>0)
  {  //用循环判断完所有节点
    while(objxmlreader.movetonextattibute)
     { //取标签和值
     strnoderesult+=" -attribute:<b>"+objxmlreader.name+"</b> value:<b>"+objxmlreader.value+"</b><br/>";
      }
   }
lblfile.text=strnoderesult;
}
}
</script>
<body>
   <h3><font face="verdana">读取xml方法四</font></h3>
    <from runat=server>
        <asp:label id="lblfile"  runat="server" />
    </from>
</body>
</html>
