方法一：使用XML控制項
    <% @ Page Language="C#"%>
<html>
<body>
       <h3><font face="Verdana">讀取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技術
<% @ 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">讀取XML方法二</font></h3>
       <from runat=server>
        <asp:Xml id="xml1" runat="server" />
      </from>

</body>
</html>

方法三：使用DataSet對象
<% @ 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">讀取XML方法三</font></h3>
<asp:DataGrid id="dgEmployees" runat="server" />

</body>
</html>

方法四：按文本方式讀取
<% @ 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:
   //讀取XML檔案頭
      strNodeResult+="XML Declaration:<b>"+objXMLReader.Name+""+objXMLReader.Value+"</b><br/>";
     break;
   case XmlNodeType.Element:
//讀取標籤
     strNodeResult+="Element:<b>"+objXMLReader.Name+"</b><br/>";
    break;
   case XmlNodeType.Text:
     //讀取值
    strNodeResult+=" -Value:<b>"+objXMLReader.Value+"</b><br/>";
   break;

   }
//判斷該節點是否有屬性
if(objXMLReader.AttributeCount>0)
{ //用迴圈判斷完所有節點
    while(objXMLReader.MoveToNextAttibute)
     { //取標籤和值
     strNodeResult+=" -Attribute:<b>"+objXMLReader.Name+"</b> value:<b>"+objXMLReader.Value+"</b><br/>";
      }
   }
LblFile.Text=strNodeResult;
}
}
</script>
<body>
   <h3><font face="Verdana">讀取XML方法四</font></h3>
       <from runat=server>
        <asp:label id="LblFile" runat="server" />
      </from>

</body>
