从 ASP.NET SOAP 服务检索 XML 数据到 ASP.NET aspx 页面

Question

当用户输入 ID 时，我有返回 XML 数据的 Web 服务。如果数据库中存在 ID，它将返回 XML 数据，现在我创建 Test Project 作为参考，我使用此 SOAP Services。

[WebMethod]
    public DataTable GetAkontasById(int Id)
    {
        OracleConnection conn = new OracleConnection("DATA SOURCE=test-1:1521/test;USER ID=test;PASSWORD=test");
        OracleDataAdapter dr = new OracleDataAdapter("Select * from AKONTAS where A_KONTO= '" + Id + "'", conn);
        DataSet ds = new DataSet();
        ds.Tables.Add("AKONTAS");
        dr.Fill(ds, "AKONTAS");
        DataTable tt = ds.Tables[0];
        return tt;
    }

这是运行Web Service后我的xml的样子

现在O创建aspx页面，其中包含作为参考Web Service. 这个aspx 也需要返回XML 数据，现在我卡在这里，不知道如何获取这个XML 数据并将其传递给aspx 页面。 你建议我怎么做？

protected void btnProjeri_Click(object sender, EventArgs e)
        {
            AkontasService.AkontasSoapClient client =
                new AkontasService.AkontasSoapClient();
            var rezultat = client.GetAkontasById(Convert.ToInt32(txtAkonto.Text));
            txtRezultat.Text = rezultat.ToString();

        } 

Answer 1

尝试以下 linq：

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

namespace ConsoleApplication132
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            string xml = File.ReadAllText(FILENAME);

            XDocument doc = XDocument.Parse(xml);

            List<XElement> AKONTAS = doc.Descendants("AKONTAS").ToList();

            var results = AKONTAS.Select(x => x.Elements().Select(y => new KeyValuePair<string, string>(y.Name.LocalName, (string)y)).ToList()).ToList();

            foreach (var result in results)
            {
                Console.WriteLine(string.Join(",", result.Select(x => x.Key + " : " + x.Value)));
            }

            Console.ReadLine();
        }
    }


}
