C#查询数据库把结果输出到XML的例子
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
using System.Data;
namespace ConsoleApplication4
{
class Program
{
static void Main(string[] args)
{
//sqlserver身份验证
//string sqlconn = "server=(local);database=keede1228;user id=sa;password=123;";
//windows身份验证
string sqlconn = "server=(local);database=keede1228;integrated security=SSPI;";
string select = "dirr4";
SqlConnection conn = new SqlConnection(sqlconn);
Console.WriteLine("33");
conn.Open();
Console.WriteLine("11");
//SqlCommand cmd = new SqlCommand(select, conn);
//SqlDataReader reader = cmd.ExecuteReader();
//while (reader.Read())
//{
// Console.WriteLine("cityid:{0} city:{1} area:{2}", reader[0], reader[1], reader[2]);
//}
SqlDataAdapter da = new SqlDataAdapter(select, conn);
DataSet ds = new DataSet();
da.Fill(ds, "custo");
foreach (DataRow row in ds.Tables["custo"].Rows)
Console.WriteLine("'{0}'from {1}", row[0], row[1]);
ds.WriteXml("write.xml", XmlWriteMode.WriteSchema);
conn.Close();
Console.WriteLine("22");
Console.ReadKey();
}
}
}
DataSet类太强大了！

其实要实现这个功能主要还是要用到javascript
方法一：
在asp.net的aspx里面的源代码中
<input type="button onclick="javascript:window.history.go(-1);"value="返回上一页">
浅析：这个是用了HTML控件，通过一个onclick的事件，调用了javascript中的一个方法就可以了。这个是最简单的了，也同样 ......
XmlDocument xmldoc = new XmlDocument();//创建xml文档对象
XmlNode root;//根节点
xmldoc.Load(Server.MapPath("address.xml"));//加载xml文档
root = xmldoc.DocumentEle ......
C# code
// Load the style sheet.
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load("output.xsl");
// Execute the transform and output the results to a file.
xslt.Transform("books.xml", "books.html");
......
