C# 从XML文件中获取数据

我需要写入一个异常表。因此，如果UploadStatus=Failed，我需要从CDR_STATUS元素中获取ClientLoanNumber和UploadedDt，然后从CDR_ERROR元素中获取后面的内容。因此，我认为CDR_状态有一个主循环，当条件UploadStatus=Failed时，它会循环通过CDR_状态元素。我需要返回ClientLoanNumber、UploadedDt和来自CDR_Status元素的消息

以下是提供者的实际响应。格式很糟糕。很抱歉我是c开发人员，所以正在寻找c。谢谢你的帮助

我将结果放入数据表：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.Data;
namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("ClientLoanNumber", typeof(string));
            dt.Columns.Add("UploadedDt", typeof(DateTime));
            dt.Columns.Add("Error", typeof(string));

            XDocument doc = XDocument.Load(FILENAME);

            List<XElement> failed = doc.Descendants("CDR_STATUS").Where(x => (string)x.Attribute("UploadStatus") == "Failed").ToList();

            foreach (var fail in failed)
            {
                DataRow newRow = dt.Rows.Add();
                newRow["ClientLoanNumber"] = (string)fail.Attribute("CWLLoanNumber");
                newRow["UploadedDt"] = DateTime.ParseExact((string)fail.Attribute("UploadedDt"), "M/dd/yyyy h:mm:ss tt", System.Globalization.CultureInfo.InvariantCulture);
                newRow["Error"] = string.Join("\n", fail.Elements("CDR_ERROR").Select(x => (string)x.Attribute("Message")));
            }

        }
    }
}

这就是我做的

            DataTable resultsDT = new DataTable();
            resultsDT.Columns.Add("LoanNUmber");
            resultsDT.Columns.Add("Error");

            XDocument X = XDocument.Load(pathStatusRequestResult);

            var status = X.Element("CWL_DATA").Element("CWL_RESPONSE");
            var statusData = status.Element("RESPONSE_DATA").Elements("CDR_STATUS");

            foreach(var item in statusData)
            {
                // returns the value of teh UploadStatus
                bool uploadStatus = (item.Attribute("UploadStatus").Value) == "Failed" ? false : true;
                string loanNumber = item.Attribute("ClientLoanNumber").Value;

                if (uploadStatus == false)
                {
                    var errorData = item.Elements("CDR_ERROR");

                    foreach(var e in errorData)
                    {
                        string error = e.Attribute("Message").Value;
                        resultsDT.Rows.Add(loanNumber, error);
                    }
                }
            }

如果您试图编写代码，但遇到特定问题，我们可以帮助您，但我们不是来从头开始编写代码的-请参阅同意@JohnM。请进行一些代码测试您是否正在将实际客户数据转储到公共网站上…？不，我仅使用测试数据如果您已经解决了问题，您可以接受自己的答案以向其他人表明问题已经解决：看起来你拿走了我的一些代码，但是你没有得到你要求的日期。实际上没有。我确实找到了一些我利用的示例代码。然后我将元素放入字符串中，直到我知道如何获取所需的项目。棘手的部分是第二圈。
