Answer 1

XmlDocument xmldoc = new XmlDocument();
//声明节
XmlDeclaration dec = xmldoc.CreateXmlDeclaration("1.0", "utf-8", null);
xmldoc.AppendChild(dec);
//加入一个根节点
XmlElement oneNode = xmldoc.CreateElement("CATALOG");
//创建节点
XmlElement twoNode = xmldoc.CreateElement("CD");

XmlElement twoNodeone = xmldoc.CreateElement("TITLE");
twoNodeone.InnerText="Empire Burlesque";
twoNode.AppendChild(twoNodeone);//添加到CD节点下面

XmlElement twoNodeone1 = xmldoc.CreateElement("ARTIST");
twoNodeone1.InnerText = "Bob Dylan";
twoNode.AppendChild(twoNodeone1);//添加到CD节点下面

XmlElement twoNodeone2 = xmldoc.CreateElement("COUNTRY");
twoNodeone2.InnerText = "USA";
twoNode.AppendChild(twoNodeone2);//添加到CD节点下面

XmlElement twoNodeone3 = xmldoc.CreateElement("COMPANY");
twoNodeone3.InnerText = "Columbia";
twoNode.AppendChild(twoNodeone3);//添加到CD节点下面

XmlElement twoNodeone4 = xmldoc.CreateElement("YEAR");
twoNodeone4.InnerText = "10.90";
twoNode.AppendChild(twoNodeone4);//添加到CD节点下面

XmlElement twoNodeone5 = xmldoc.CreateElement("PRICE");
twoNodeone5.InnerText = "1985";
twoNode.AppendChild(twoNodeone5);//添加到CD节点下面

oneNode.AppendChild(twoNode);//添加到CATALOG节点下面
//创建节点,第二个CD节点
XmlElement twoNode1 = xmldoc.CreateElement("CD");

XmlElement twoNodeone123 = xmldoc.CreateElement("TITLE");
twoNodeone123.InnerText = "Empire Burlesque";
twoNode1.AppendChild(twoNodeone123);//添加到CD节点下面

XmlElement twoNodeone11 = xmldoc.CreateElement("ARTIST");
twoNodeone11.InnerText = "Bob Dylan";
twoNode1.AppendChild(twoNodeone11);//添加到CD节点下面

XmlElement twoNodeone22 = xmldoc.CreateElement("COUNTRY");
twoNodeone22.InnerText = "USA";
twoNode1.AppendChild(twoNodeone22);//添加到CD节点下面

XmlElement twoNodeone33 = xmldoc.CreateElement("COMPANY");
twoNodeone33.InnerText = "Columbia";
twoNode1.AppendChild(twoNodeone33);//添加到CD节点下面

XmlElement twoNodeone44 = xmldoc.CreateElement("YEAR");
twoNodeone44.InnerText = "10.90";
twoNode1.AppendChild(twoNodeone44);//添加到CD节点下面

XmlElement twoNodeone45 = xmldoc.CreateElement("PRICE");
twoNodeone45.InnerText = "1985";
twoNode1.AppendChild(twoNodeone45);//添加到CD节点下面

oneNode.AppendChild(twoNode1);//添加到CATALOG节点下面
xmldoc.AppendChild(oneNode);
xmldoc.Save(Server.MapPath("")+"/1.xml");//保存xml

注意：cd节点可以通过循环添加到CATALOG节点下面

Answer 2

N级都可以，递归啊！

Answer 3

private void xmlwriter(string startStr,string secondStr,string[] elementStr,string[] elementName)
{
XmlTextWriter writer = new XmlTextWriter(Server.MapPath("phone4.xml"), null);
writer.Formatting = Formatting.Indented; //缩进格式
writer.Indentation = 4;

writer.WriteStartDocument();

writer.WriteStartElement(startStr);

writer.WriteStartElement(secondStr);

int count = 0;
foreach (string str in elementName)
{
writer.WriteStartElement(str);
writer.WriteString(elementStr[count]);
writer.WriteEndElement();
count++;
}
writer.WriteEndElement();
writer.WriteEndElement();

writer.Flush();
writer.Close();

}

写了个面向过程的函数。。不是好办法，你可以考虑下把xml和对象对应起来创建，这样更灵活。

Answer 4

用DataSet("CATALOG")下面建一个DataTable("CD")，表内建立所需要的DataColumn，把DataRow逐行加入，最后用DataSet类的WriteXml方法写到文件即可。
