现在我想动态解析这个文件，这意味着当我回发时它应该解析解析为字符串的 XML 并根据需要存储值。我不明白我怎样才能实现它。我试过的代码是这样的，它确实根据需要将文件下载到 XML 文件中，但它是一行并编码的。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using System.Text;
using System.Threading;

public partial class Services_Ingram_Test : System.Web.UI.Page
{
    public Dictionary<string, List<string>> myCodes = new Dictionary<string, List<string>>();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.ContentLength > 0)
        {
            try
            {
                byte[] buf = new byte[Request.ContentLength];
                buf = Request.BinaryRead(Request.ContentLength);
                string s = Encoding.UTF8.GetString(buf); 



                using (StreamWriter Streamwriter = new StreamWriter(HttpContext.Current.Server.MapPath("~/temp/") + System.DateTime.Now.ToFileTimeUtc().ToString() + ".xml"))
                {
                    Streamwriter.Write(s);
                    Streamwriter.Close();
                    Streamwriter.Dispose();
                }
                UpdateLogFile("Data saved");
                //if (!IsResponseASN(s))
                //    UpdatePOWithConfirmation(s);

                Response.ContentType = "Text/XML";
                Stream sw = Response.OutputStream;
                byte[] byteArray = Encoding.UTF8.GetBytes("OK");

                sw.Write(byteArray, 0, byteArray.Length);
                sw.Close();
            }
            catch (Exception ex)
            {
                Stream sw = Response.OutputStream;
                byte[] byteArray = Encoding.UTF8.GetBytes(ex.Message);
                sw.Write(byteArray, 0, byteArray.Length);
                sw.Close();
                //Response.Write(ex.Message.ToString());
                UpdateLogFile("Error: " + ex.ToString());
            }
        }
    }
    private void UpdateLogFile(string s)
    {

        using (StreamWriter Streamwriter = new StreamWriter(HttpContext.Current.Server.MapPath("~/temp/ack.log"), true))
        {
            Streamwriter.Write(DateTime.Now.ToString("MM-dd-yyyy hh:mm:ss"));
            Streamwriter.Write(s);
            Streamwriter.Write(Environment.NewLine);
            Streamwriter.Close();
            Streamwriter.Dispose();
        }
    }
}

将 xml 作为字符串发布到 Web 服务器后，尝试类似的操作:

var xDocument = System.Xml.Linq.XDocument.Parse("<somenode>Some values</somenode>");
