在asp.net中读取XML文件信息的4种方法

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>
