作者:Dezai.CN / 发布于2013/6/26/ 904


	XmlDocument xdoc = new XmlDocument();
	 string strDirlist = this.txtName.Text;
	 string outstring = "";
	 DirectoryInfo thisOne = new DirectoryInfo(strDirlist);
	 FileInfo[] fileInfo = thisOne.GetFiles();
	 //循环xml文件
	 foreach (FileInfo fi in fileInfo)
	 {
	 if (fi.Extension.ToUpper().ToString() == ".XML")
	 {
	 xdoc.Load(strDirlist + "//" + fi.Name.ToString());
	 XmlNodeList nodelist = xdoc.SelectNodes("//Activity");
	 bool ss = false;
	 //循环每个文件的节点Activity
	 foreach (XmlNode node in nodelist)
	 {
	 XmlNode node1 = node.SelectSingleNode("CodeName");
	 XmlNode node2 = node.SelectSingleNode("Resources");
	 if (node1.InnerText.ToString().ToUpper() == "WAIT" && node2 == null)
	 {
	 XmlNode node3 = node.SelectSingleNode("DefaultSelectUsers");
	 if (node3 == null)
	 {
	 XmlElement xe = xdoc.CreateElement("DefaultSelectUsers");
	 xe.InnerText = "True";
	 node.InsertAfter(xe, node1);
	 XmlElement xe1 = xdoc.CreateElement("Resources");
	 xe1.InnerXml = "<User key='' logonName='hengxing' />";
	 node.InsertAfter(xe1, xe);

	 }
	 else
	 {
	 node3.InnerText = "True";
	 XmlElement xe1 = xdoc.CreateElement("Resources");
	 xe1.InnerXml = "<User key='' logonName='hengxing' />";
	 node.InsertAfter(xe1, node3);
	 }
	 ss = true;
	 // Response.Write(" <a href= 'ss ' target= '_blank '> " + fi.Name.ToString() + " </a> " + "  ");
	 }

	 }
	 if (ss)
	 {
	 xdoc.Save(strDirlist + "//" + fi.Name.ToString());
	 ss = false;

	 }

	同时要修改xml文件,文件必须非只读

试试其它关键字
