Question

我有一个XML文档，我想读取，展平并返回我称为PMRow的对象的List <>。对于XML中的每个CodingRow，应该有一个对应的List元素，并且发票的“标题”详细信息应该简单地重复。在此转换中，无论是在发票级别还是在CodingRow级别，许多XML元素都将被忽略。我已经开始编写下面的代码，而且我无法概念化从那里去的地方：

代码不完整：

public static List<PMRow> ParseToPMRows(FileInfo myFile)
{
    var xDoc = XDocument.Load(myFile.FullName);

    var query = from element in xDoc.Element("InvoiceDocument").Element("Invoice").Element("CodingRows").Elements("CodingRow")
                select 
}

目标类别：

public class PMRow
{
    public string SupplierCode { get; set; }
    public string InvoiceNumber { get; set; }
    public DateTime InvoiceDate { get; set; }
    public decimal GrossSum { get; set; }
    public decimal NetSum { get; set; }
    public decimal TaxSum { get; set; }
    public decimal CR_GrossSum { get; set; }
    public string AccountNumber { get; set; }
    public string DimCode1 { get; set; }
}

概念化目标（列表中两个PMRow类型的对象）：

AQUINC，180928003802901，2018/9/26，700，700，0，500，1990，01

AQUINC，180928003802901，2018/9/26，700，700，0，200，2390，02

Answer 1

这是您要寻找的吗？

=INDEX($A$1:$E$2, MOD(COLUMN(A:A)-1, 2)+1, (COLUMN(A:A)-1)/2+1)

注意：以上假设所有元素都将存在且有效。如果不是这种情况，则需要为此添加适当的处理。

Answer 2

通常，我发现首先将XML序列化为类对象然后对序列化的对象进行迭代更方便。

您只需要

XmlSerializer serializer = new XmlSerializer(typeof(Invoice));

TextReader reader = new StringReader(source);

Invoice resultObj = (Invoice)serializer.Deserialize(reader);

var pmRows = resultObj.CodingRows.CodingRow.Select(item => new PMRow
{
     CR_GrossSum = Convert.ToDecimal(resultObj.GrossSum.Text),
     InvoiceDate = Convert.ToDateTime(resultObj.InvoiceDate.Text),
     InvoiceNumber = resultObj.InvoiceNumber.Text,
     SupplierCode = resultObj.SupplierCode.Text,
     NetSum = Convert.ToDecimal(resultObj.NetSum.Text),
     GrossSum = Convert.ToDecimal(resultObj.GrossSum.Text),
     TaxSum = Convert.ToDecimal(resultObj.TaxSum.Text),
     AccountNumber = item.AccountCode.Text,
     DimCode1 = item.DimCode1.Text
 }).ToList();

请尝试以下代码。我假设它们在一个文件中是多个发票，所以我不得不使用SelectMany（）返回平面列表

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

namespace ConsoleApplication75
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            ParseToPMRows(FILENAME);
        }
        public static List<PMRow> ParseToPMRows(string myFile)
        {
            XDocument xDoc = XDocument.Load(myFile);


            var tempResults = xDoc.Descendants("Invoice").Select(x => new {
                supplierCode = (string)x.Element("SupplierCode"),
                invoiceNumber = (string)x.Element("InvoiceNumber"),
                invoiceDate = (DateTime)x.Element("InvoiceDate"),
                grossSum = (decimal)x.Element("GrossSum"),
                netSum = (decimal)x.Element("NetSum"),
                taxSum = (decimal)x.Element("TaxSum"),
                codingRows = x.Descendants("CodingRow").Select(y => new {
                    crGrossSum = (decimal)y.Element("GrossSum"),
                    accounNumber = (string)y.Element("AccountCode"),
                    dimCode1 = (string)y.Element("DimCode1")
                }).ToList()
            }).ToList();

            List<PMRow> rows = tempResults.Select(x => x.codingRows.Select(y => new PMRow()
            {
                SupplierCode = x.supplierCode,
                InvoiceNumber = x.invoiceNumber,
                InvoiceDate = x.invoiceDate,
                GrossSum = x.grossSum,
                NetSum = x.netSum,
                TaxSum = x.taxSum,
                CR_GrossSum = y.crGrossSum,
                AccountNumber = y.accounNumber,
                DimCode1 = y.dimCode1
            })).SelectMany(x => x).ToList();

            return rows;
         }
    }
    public class PMRow
    {
        public string SupplierCode { get; set; }
        public string InvoiceNumber { get; set; }
        public DateTime InvoiceDate { get; set; }
        public decimal GrossSum { get; set; }
        public decimal NetSum { get; set; }
        public decimal TaxSum { get; set; }
        public decimal CR_GrossSum { get; set; }
        public string AccountNumber { get; set; }
        public string DimCode1 { get; set; }
    }
}

对于一张发票，您可以使用以下内容：

        public static List<PMRow> ParseToPMRows(string myFile)
        {
            XDocument xDoc = XDocument.Load(myFile);


            var tempResults = xDoc.Descendants("Invoice").Select(x => new {
                supplierCode = (string)x.Element("SupplierCode"),
                invoiceNumber = (string)x.Element("InvoiceNumber"),
                invoiceDate = (DateTime)x.Element("InvoiceDate"),
                grossSum = (decimal)x.Element("GrossSum"),
                netSum = (decimal)x.Element("NetSum"),
                taxSum = (decimal)x.Element("TaxSum"),
                codingRows = x.Descendants("CodingRow").Select(y => new {
                    crGrossSum = (decimal)y.Element("GrossSum"),
                    accounNumber = (string)y.Element("AccountCode"),
                    dimCode1 = (string)y.Element("DimCode1")
                }).ToList()
            }).FirstOrDefault();

            List<PMRow> rows = tempResults.codingRows.Select(x => new PMRow()
            {
                SupplierCode = tempResults.supplierCode,
                InvoiceNumber = tempResults.invoiceNumber,
                InvoiceDate = tempResults.invoiceDate,
                GrossSum = tempResults.grossSum,
                NetSum = tempResults.netSum,
                TaxSum = tempResults.taxSum,
                CR_GrossSum = x.crGrossSum,
                AccountNumber = x.accounNumber,
                DimCode1 = x.dimCode1
            }).ToList();

            return rows;
         }
