c# 将数据导出成指定xml格式
Dataset的WriteXml是按记录一条一条的写成XML，对应的，不可能给你写成分省市的，必须要自己写循环判断，自己构造xml
用select * from [TableName] order by PROVINCE, CITY, COUNTRY, TOWN这条语句查询出结果，这样记录是按省市乡镇依次排列的，读到DataTable里，再循环读取，当前记录与前一条记录进行比对，如果省市乡都一样就追加“<town name="" /> ”，如果省市一样，追加<country>,如果只是省一样，追加<city>,全部遍历一遍，构造xml字符串即可。
补充：
protected void WriteXML()
{
DataTable dt = new YourClass().YourMethod();//你的类.你的方法
string str = "<address>";
for (int i = 0; i < dt.Rows.Count; i++)
{
if (i == 0)
{
str += "<province name=\"" + dt.Rows[i]["Province"].ToString() + "\">" +
"<city name=\"" + dt.Rows[i]["City"].ToString() + "\">" +
"<country name=\"" + dt.Rows[i]["Country"].ToString() + "\">" +
"<town name=\"" + dt.Rows[i]["Town"].ToString() + "\" />";
}
else
{
if (dt.Rows[i]["Province"].ToString() == dt.Rows[i - 1]["Province"].ToString() &&
dt.Rows[i]["City"].ToString() == dt.Rows[i - 1]["City"].ToString() &&
dt.Rows[i]["Country"].ToString() == dt.Rows[i - 1]["Country"].ToString())
{

说明：只支持一个省的，要是多个省的你再稍做改动
