XmlDataSource oXmlDataSource = new XmlDataSource(); oXmlDataSource.XPath = "siteMap/siteMapNode"; XmlDocument doc = new XmlDocument(); doc.Load(Server.MapPath("~/Web/sitemap/LoadRole.xml")); XmlNode root = doc.DocumentElement; XmlNodeList nodeList = doc.SelectNodes("/RolesList/Roles[@ID=" + UserRole + "]"); drpUpdateRole.Items.Insert(0, new ListItem(string.Empty, string.Empty)); List<ListItem> items = new List<ListItem>(); foreach (XmlNode node in nodeList) { for (int i = 0; i < node.ChildNodes.Count; i++) { items.Add(new ListItem(node.ChildNodes[i].Attributes["text"].Value, node.ChildNodes[i].Attributes["value"].Value)); } } drpUpdateRole.Items.AddRange(items.ToArray());

嗨 只是我修改了你的代码并根据你的需要制作...... Hi just i modified your code and make it according to your need... { XmlDataSource oXmlDataSource = new XmlDataSource(); oXmlDataSource.XPath = "siteMap/siteMapNode"; XmlDocument doc = new XmlDocument(); doc.Load(Server.MapPath(".") + "\\LoadRole.xml"); XmlNode root = doc.DocumentElement; // XmlNodeList nodeList = doc.SelectNodes("/RolesList/Roles[@ID=" + UserRole + "]"); XmlNodeList nodeList = doc.SelectNodes("/RolesList/Roles[@ID=01]"); drpUpdateRole.Items.Insert(0, new ListItem(string.Empty, string.Empty)); List<ListItem> items = new List<ListItem>(); foreach (XmlNode node in nodeList) { for (int i = 0; i < node.ChildNodes.Count; i++) { string text = node.ChildNodes[i].InnerXml; string xml = @"<Test>" + text + "</Test>"; XDocument doc2 = XDocument.Parse(xml); //Get your wood nodes and values in a list List<Tuple<string, string>> list = doc2.Descendants().Select(a => new Tuple<string, string>(a.Name.LocalName, a.Value)).ToList(); items.Add(new ListItem(list[1].Item2, list[2].Item2)); } } drpUpdateRole.Items.AddRange(items.ToArray()); }
