如何用DataSet生成指定结构的XML？？

Question

用如下代码建立的DataSet生成XML，使用DataSet.WriteXml()方法。DataSet ds = new DataSet ("setup");
DataTable dtCuntry = new DataTable ("country");
DataTable dtColumn = new DataTable ("column");dtCuntry.Columns.Add (new DataColumn ("id", typeof (System.String)));
dtCuntry.Columns.Add (new DataColumn ("name", typeof (System.String)));dtCuntry.Rows.Add (new object[] {"1","china"});
dtCuntry.Rows.Add (new object[] {"2", "USA"});dtColumn.Columns.Add (new DataColumn ("id", typeof (System.String)));
dtColumn.Columns.Add (new DataColumn ("name", typeof (System.String)));dtColumn.Rows.Add (new object[] { "1","XXX"});ds.Tables.Add(dtCuntry);
ds.Tables.Add(dtColumn);结果是：
<setup>
  <country>
    <id>1</id>
    <name>china</name>
  </country>
  <country>
    <id>2</id>
    <name>USA</name>
  </country>
  <column>
    <id>1</id>
    <name>XXX</name>
  </column>
</setup>不是想要的结构，怎样才能生成如下结构的XML：
<setup>
  <country>
    <record>
      <id>1</id>
      <name>china</name>
    </record>
    <record>
      <id>2</id>
      <name>USA</name>
    </record>
  </country>
  <column>
    <record>
      <id>1</id>
      <name>XXX</name>
    </record>
  </column>
</setup>

DataSet可能实现不了XmlTextWriter可以实现你的想法
直接用XmlTextWriter来写文件w.WriteStartDocument();
w.WriteRaw("\n");
w.WriteStartElement("setup");
w.WriteRaw("\n");w.WriteStartDocument();
w.WriteRaw("\n");
w.WriteRaw(TAB(1));
w.WriteStartElement("country");
w.WriteRaw("\n");w.WriteStartDocument();
w.WriteRaw("\n");
w.WriteRaw(TAB(2));
w.WriteStartElement("record");
w.WriteRaw("\n");
..............
w.close();
