【问题描述】：

我有这个 xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<pippo:Response xmlns:pippo="http://pippoonboarding.eu">
  <pippo:Header>
    <pippo:FileId>123</pippo:FileId>
    <pippo:SenderId>1234</pippo:SenderId>
    <pippo:ProcessingDate>20210630</pippo:ProcessingDate>
    <pippo:ProcessingTime>1130</pippo:ProcessingTime>
    <pippo:ResponseCode>OK</pippo:ResponseCode>
  </pippo:Header>
  <pippo:CompanyResponse>
    <pippo:SellerId>1234</pippo:SellerId>
    <pippo:SellerContractCode />
    <pippo:VATNumber>123456</pippo:VATNumber>
    <pippo:ResponseCode>KO</pippo:ResponseCode>
    <pippo:PippoCompanyCode />
    <pippo:ResponseDetails>
      <pippo:Entity>ciaone</pippo:Entity>
      <pippo:ProgressiveNumber>1</pippo:ProgressiveNumber>
      <pippo:PippoShopCode />
      <pippo:TerminalId />
      <pippo:FieldName />
      <pippo:ErrorType>DDD</pippo:ErrorType>
      <pippo:ErrorCode>1234</pippo:ErrorCode>
      <pippo:ErrorDescription>test</pippo:ErrorDescription>
    </pippo:ResponseDetails>
  </pippo:CompanyResponse>
</pippo:Response>

我想反序列化到我的班级：

public class XmlDeserializer

    [Serializable, XmlRoot("pippo:Response xmlns:pippo=\"http://pippoonboarding.eu\"")]
    public class Root
    
        public string Response  get; set; 

        //[XmlElement(ElementName = "Header")]
        public Header Header  get; set; 

        public CompanyResponse CompanyResponse  get; set; 

    

    public class Header
    
        public string FileId  get; set; 
        public string SenderId  get; set; 
        public string ProcessingDate  get; set; 
        public string ProcessingTime  get; set; 
        public string ResponseCode  get; set; 

    

    public class CompanyResponse
    
        public string SellerId  get; set; 
        public int SellerContractCode  get; set; 
        public int VATNumber  get; set; 
        public int ResponseCode  get; set; 
        public int PippoCompanyCode  get; set; 
        public ResponseDetails ResponseDetails  get; set; 

    

    public class ResponseDetails
    
        public string Entity  get; set; 
        public string ProgressiveNumber  get; set; 
        public string PippoShopCode  get; set; 
        public string TerminalId  get; set; 
        public string FieldName  get; set; 
        public string ErrorType  get; set; 
        public string ErrorCode  get; set; 
        public string ErrorDescription  get; set; 

    

但我收到此错误：

XML 文档 (2, 2) 中存在错误。 <Response xmlns='http://pippoonboarding.eu'> 不是预期的。

错误是什么意思？我该怎么办？

【参考方案1】：

以下代码有效。必须在类定义中将一些整数更改为字符串。

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

namespace ConsoleApplication2

    class Program
    
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        
            XmlDeserializer response = new XmlDeserializer(FILENAME);

        
    
    public class XmlDeserializer
    
        public XmlDeserializer(string filename)
        
            XmlReader reader = XmlReader.Create(filename);
            XmlSerializer serializer = new XmlSerializer(typeof(Root));
            Root response = (Root)serializer.Deserialize(reader);
        

        [XmlRoot(ElementName = "Response", Namespace = "http://pippoonboarding.eu")]
        public class Root
        
            public string Response  get; set; 
            //[XmlElement(ElementName = "Header")]
            public Header Header  get; set; 
            public CompanyResponse CompanyResponse  get; set; 
        
        public class Header

            public string ProcessingTime  get; set; 
            public string ResponseCode  get; set; 
        
        public class CompanyResponse
        
            public string SellerId  get; set; 
            public string SellerContractCode  get; set;
