<div>
protected void Button1_Click(object sender, EventArgs e)
{
Random random=new Random();
int rnumber=random.Next(1, 100);
string outPutName = DateTime.Now.ToString("yyyyMMddhhmmss") + rnumber.ToString();
HttpResponse resp;
resp = Page.Response;
resp.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
resp.ContentType = "text/xml";
resp.AddHeader("Content-Disposition",
"attachment; filename=" + System.Web.HttpUtility.UrlEncode(outPutName, System.Text.Encoding.UTF8) + ".xml");
this.EnableViewState = false;
DataTable dt = new DataTable();
if (!string.IsNullOrEmpty(txtDONos.Text.Trim()))
{
DistributeOrderBLL doBll = new DistributeOrderBLL();
string strDistributeOrderNos = txtDONos.Text.Trim();
dt = doBll.GetDistributeOrderByDistributeOrderNos
(strDistributeOrderNos);
}
DataSet ds = new DataSet();
ds.Tables.Add(dt);
StringBuilder xmlData = new StringBuilder();
xmlData.AppendLine(@"<?xml version='1.0' encoding='UTF-8' ?>");
xmlData.AppendLine(@"<root>"); 
foreach (DataRow dr in dt.Rows)
{
xmlData.AppendLine(@"<person");
xmlData.AppendLine(@" id='" + dr["Name"] + "' ");
xmlData.AppendLine(@">");
xmlData.AppendLine(@"<name>" + dr["Name"] + "</name>");
xmlData.AppendLine(@"<address>" + dr["Street"] + "</address>");
xmlData.AppendLine(@"<city>" + dr["CityName"] + "</city>");
xmlData.AppendLine(@"</person>");
}
xmlData.AppendLine(@"</root>");
Response.Write(xmlData.ToString());
Response.End();
}另外一种办法
public void toMakXmlFile(ArrayList lfname, ArrayList lfile,string xmlName)
{

System.IO.StringWriter sw = new System.IO.StringWriter();
xmlW = new XmlTextWriter(sw);
xmlW.Formatting = Formatting.Indented;
xmlW.WriteStartElement("Lables");
for (int i = 0; i < lfile.Count; i++)
{
xmlW.WriteStartElement("LableItem");


xmlW.WriteStartElement("lfile");
xmlW.WriteAttributeString("lfname", (string)lfname[i]);
xmlW.WriteString((string)lfile[i]);
xmlW.WriteEndElement();

xmlW.WriteEndElement();
}
xmlW.WriteEndElement();

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8"); // 中文 
HttpContext.Current.Response.AppendHeader("content-disposition", "attachment;filename=\"" + xmlName + ".xml\"");
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();

}
读取的一种办法
//读取xml文件
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(e.FullPath);
XmlNode xn = xmlDoc.SelectSingleNode("root");
XmlNodeList xnl = xn.ChildNodes;
foreach (XmlNode xnf in xnl)
{
XmlElement xe = (XmlElement)xnf;
XmlNodeList xnf1 = xe.ChildNodes;
string name = xnf1.Item(0).InnerText;
string address = xnf1.Item(1).InnerText;
string city = xnf1.Item(2).InnerText;
string state = xnf1.Item(3).InnerText;
string postcode = xnf1.Item(4).InnerText;
string country = xnf1.Item(5).InnerText;
string phone1 = xnf1.Item(6).InnerText;
}
