Answer 3

protected void Page_Load(object sender, EventArgs e) 
{ 
    string xmlFile = Server.MapPath("xmlfilename.xml"); 
    XmlTextReader reader = new XmlTextReader(xmlFile); 
    while (reader.Read()) 
    { 
        if (reader.NodeType == XmlNodeType.Element) 
        { 
            if (reader.Name == "节点名称") 
            { 
                Response.Write(reader.ReadString()); 
            } 
            if (reader.Name == "节点名称") 
            { 
                Response.Write(reader.ReadString()); 
                Response.Write("<br />"); 
            } 
        } 
    } 
    reader.Close(); 
} 

Answer 4

 XmlDocument document = new XmlDocument();
            document.Load(Server.MapPath("~/site/site.xml"));
            XmlNodeList nodelist = document.SelectNodes("web");
            XmlNode node = nodelist.Item(0);
            this.name.Value = node["title"].InnerText;
            this.logoimg.Src = node["logourl"].InnerText;
            this.description.Value = node["description"].InnerText;
            this.keywrods.Value = node["keywrods"].InnerText;
            this.flow.Value = node["flow"].InnerText;
            this.mapapi.Value = node["mapapi"].InnerText;

这是我自己总结写的操作xml类，希望可以帮到楼主

Answer 9

FileStream XMLStream = new FileStream(cfileName,FileMode.CreateNew);
                XmlTextWriter XmlWrite = new XmlTextWriter(XMLStream,Encoding.Unicode);
                XmlWrite.Formatting = Formatting.Indented;
                try
                {
                    XMLBuilWriter(XmlWrite,XMLLogList);
                    XmlWrite.Close();
                }
                catch(Exception ex)
                {
                    cRe = ex.Message.ToString();
