Answer 1

Usually it's a good idea to check out official documentation .

If you get a class for this xml you can use this tool or using this visual studio functionality

Also this xml will not parse, you are using strange apostrophes in the trans_name line

Answer 2

Use xml linq :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;

namespace ConsoleApplication62
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            string xml = File.ReadAllText(FILENAME);
            XDocument doc = XDocument.Parse(xml);

            var results = doc.Descendants("response").FirstOrDefault().Elements("alipay").Select(x => new
            {
                alipay_trans_id = (string)x.Element("alipay_trans_id"),
                partner_trans_id = (string)x.Element("partner_trans_id"),
                alipay_buyer_login_id = (string)x.Element("alipay_buyer_login_id"),
                alipay_buyer_user_id = (string)x.Element("alipay_buyer_user_id"),
                alipay_pay_time = (string)x.Element("alipay_pay_time"),
                exchange_rate = (decimal)x.Element("exchange_rate"),
                trans_amount = (decimal)x.Element("trans_amount"),
                trans_amopunt_CNY = (decimal)x.Element("alipay_trans_id"),
                result_code = (string)x.Element("result_code")
            }).FirstOrDefault();

        }
    }
}
