Answer 1

winform可以用xmltextwriter的对象方法来写

Answer 2

如果楼主只要想生成XML文档,采用XmlDocument的方式的效率远不如XmlReader和XmlWriter
不过楼主既然需要,给你一个demoXmlDocument doc=new XmlDocument();
        XmlNode root=doc.CreateNode(XmlNodeType.XmlDeclaration,"","");
        doc.AppendChild(root);
        
        XmlNode newNode1=doc.CreateNode(XmlNodeType.Element,"NewDataSet",null);
        XmlNode newNode2=doc.CreateNode(XmlNodeType.Element,"ChapDescri",null);
        XmlNode newNode3=doc.CreateNode(XmlNodeType.Element,"id",null);
        XmlNode txtNode1 = doc.CreateTextNode("1");
        newNode3.AppendChild(txtNode1);
        newNode3.LastChild.Value = "1";
        XmlNode newNode4=doc.CreateNode(XmlNodeType.Element,"username",null);
        XmlNode txtNode2 = doc.CreateTextNode("admin");
        newNode4.AppendChild(txtNode2);
        XmlNode newNode5=doc.CreateNode(XmlNodeType.Element,"userpass",null);
        XmlNode txtNode3 = doc.CreateTextNode("admin");
        newNode5.AppendChild(txtNode3);
        newNode2.AppendChild(newNode3);
        newNode2.AppendChild(newNode4);
        newNode2.AppendChild(newNode5);
        newNode1.AppendChild(newNode2);
        
        doc.AppendChild(newNode1);        doc.Save("d:\\test.xml");

Answer 3

如果你的信息固定,有一种简单的方式.建议楼上先看看XML基础        XmlDocument doc = new XmlDocument();
        doc.LoadXml("<?xml   version=\"1.0\"   encoding=\"utf-8\"   ?>" +
   "<NewDataSet> " +
   "<ChapDescri> " +
    "<id> 1 </id> " +
    "<username> admin </username> " +
    "<userpass> admin </userpass>" +
    "</ChapDescri> " +
    "<ChapDescri>" +
    "<id> 2 </id> " +
    "<username> ajian </username> " +
    "<userpass> 123456 </userpass> " +
    "</ChapDescri> " +
   "<ChapDescri> " +
    "<id> 3 </id> " +
    "<username> woshizhu </username> " +
    "<userpass> ok </userpass>" +
    "</ChapDescri> " +
    "<Table> " +
    "<id> 1 </id> " +
    "<username> admin </username> " +
    "<userpass> admin </userpass> " +
    "</Table> " +
    "<Table> " +
    "<id> 2 </id> " +
    "<username> ajian </username>" +
    "<userpass> 123456 </userpass> " +
    "</Table>" +
    "<Table> " +
    "<id> 3 </id> " +
    "<username> woshizhu </username>" +
    "<userpass> ok </userpass> " +
    "</Table> " +
    "</NewDataSet> ");
        doc.Save("d:\\test.xml");    }
