UBL2.1XML反序列化C#列表/数组

Question

我很难对部分发票XML进行反序列化。

标签cac:InvoiceLine正在重复。

我需要帮助为元素InvoiceLine创建列表/数组，并执行foreach循环并从子元素中提取值。

这是XML文件的示例。

我在Visual中生成了类

将XML数据复制到剪贴板

2在VS中，编辑>粘贴特殊>“粘贴Xml作为类”

这是我从xml获取所有其他值的代码。

static void Main(string[] args)
        {
            XmlSerializer serializer =
            new XmlSerializer(typeof(XmlStr.DocumentEnvelope));
            // Declare an object variable of the type to be deserialized.
            XmlStr.DocumentEnvelope envelope;
            using (Stream reader = new FileStream(@"C:\\Users\\Desktop\\24.xml", FileMode.Open))
            {
                // Call the Deserialize method to restore the object's state.
                envelope = (XmlStr.DocumentEnvelope)serializer.Deserialize(reader);
            }
            // Write out the properties of the object.
            Console.WriteLine(envelope.DocumentBody.Invoice.ID.Value);
        }

当我使用下面的代码时，会出现错误。

System.InvalidOperationException：“XML文档(2，2)中有一个错误。”

内部异常

InvalidOperationException:没想到<DocumentEnvelope xmlns='urn:eFaktura:MinFinrs:envelop:schema'>。

XmlSerializer serializer =
           new XmlSerializer(typeof(zaglavlje.InvoiceLine[]));
            // Declare an object variable of the type to be deserialized.
            zaglavlje.InvoiceLine[] envelope;
            using (Stream reader = new FileStream(@"C:\\Users\\Desktop\\24.xml", FileMode.Open))
            {
                // Call the Deserialize method to restore the object's state.
                envelope = (zaglavlje.InvoiceLine[])serializer.Deserialize(reader);
            }
            // Write out the properties of the object.
            //Console.WriteLine(envelope);

我想要这样的InvoiceLine

第一环

ID: 1

InvoicedQuantity: 65

LineExtensionAmount: 3971.5

Item.Name:第1行描述

Price.PriceAmount: 61.1

BaseQuantity: 1

第二回路

ID: 2

InvoicedQuantity: 65

LineExtensionAmount: 2535

Item.Name:第2行描述

Price.PriceAmount: 39

BaseQuantity: 1

使用客户序列化：

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

namespace ConsoleApplication2
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(FILENAME);
            XmlSerializer serializer = new XmlSerializer(typeof(DocumentEnvelope));
            DocumentEnvelope envelope = (DocumentEnvelope) serializer.Deserialize(reader);
        }
    }
    [XmlRoot(Namespace = "urn:eFaktura:MinFinrs:envelop:schema")]
    public class DocumentEnvelope
    {
        public DocumentBody DocumentBody { get; set; }
    }
    public class DocumentBody
    {
        [XmlElement(Namespace = "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2")]
        public Invoice Invoice { get; set; }
    }
    public class Invoice
    {
        [XmlElement(ElementName = "InvoiceLine", Namespace = "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2")]
        public List<InvoiceLine> InvoiceLine { get; set; }
    }
    public class InvoiceLine : IXmlSerializable
    {
        public int InvoicedQuantity { get; set; }
        public decimal LineExtensionAmount { get; set; }
        public string ItemName { get; set; }
        public decimal PriceAmount { get; set; }
        public decimal  BaseQuantity { get; set; }

        public void WriteXml(XmlWriter writer)
        {
            
        }

        public void ReadXml(XmlReader reader)
        {
            XElement invoiceLine = (XElement)XElement.ReadFrom(reader);
            XNamespace ns = invoiceLine.Name.Namespace;


            InvoicedQuantity = (int)invoiceLine.Elements().Where(x => x.Name.LocalName == "InvoicedQuantity").First();
            LineExtensionAmount = (decimal)invoiceLine.Elements().Where(x => x.Name.LocalName == "LineExtensionAmount").First();
            ItemName = (string)invoiceLine.Descendants().Where(x => x.Name.LocalName == "Name").FirstOrDefault();
            PriceAmount = (decimal)invoiceLine.Descendants().Where(x => x.Name.LocalName == "PriceAmount").FirstOrDefault();
            BaseQuantity = (decimal )invoiceLine.Descendants().Where(x => x.Name.LocalName == "BaseQuantity").FirstOrDefault();
        }
        public XmlSchema GetSchema()
        {
            return (null);
        }

    }


}

Answer 2

谢谢@jdweng

我试过你的代码，效果很好。

我还成功地修改了我的代码，以获得InvoiceLine的计数和do循环。

static void Main(string[] args)
{

    XmlSerializer serializer =
    new XmlSerializer(typeof(zaglavlje.DocumentEnvelope));
    // Declare an object variable of the type to be deserialized.
    zaglavlje.DocumentEnvelope envelope;
    using (Stream reader = new FileStream(FILENAME, FileMode.Open))
    {
        // Call the Deserialize method to restore the object's state.
        envelope = (zaglavlje.DocumentEnvelope)serializer.Deserialize(reader);
    }

    int xxx = envelope.DocumentBody.Invoice.InvoiceLine.Count();
    for (int i = 0; i < xxx; i++)
    {
        Console.WriteLine("No: " + envelope.DocumentBody.Invoice.InvoiceLine[i].ID.Value);
        Console.WriteLine("Name: " + envelope.DocumentBody.Invoice.InvoiceLine[i].Item.Name);
    }
}
