反序列化 XML 并在 XML 文档中出错 (2, 2)

分类：编程问答

如何解决反序列化 XML 并在 XML 文档中出错 (2, 2)

我有一个 XML 文件，我正在从中读取并尝试反序列化为一个对象。尝试时出现此错误：

system.invalidOperationException: 'XML 文档 (2,2) 中存在错误。' InvalidOperationException: 不是预期的。

这里是 XML 文件：

<?xml version="1.0" encoding="utf-8" ?>
<ns6:ACABulkRequestTransmitterStatusDetailResponse xmlns="urn:us:gov:treasury:irs:ext:aca:air:ty20" xmlns:ns2="urn:us:gov:treasury:irs:common" xmlns:ns3="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:ns4="http://www.w3.org/2000/09/xmldsig#" xmlns:ns5="urn:us:gov:treasury:irs:msg:acasecurityheader" xmlns:ns6="urn:us:gov:treasury:irs:msg:irstransmitterstatusrequest">
    <ACABulkRequestTransmitterResponse>
        <TransmissionStatusCd>Rejected</TransmissionStatusCd>
        <ns2:ReceiptId>AATS1094B-21-00008699</ns2:ReceiptId>
    </ACABulkRequestTransmitterResponse>
    <ACABulkReqTrnsmtStsRespGrpDtl>
        <ns2:BulkExchangeFile>
            <xop:Include xmlns:xop="http://www.w3.org/2004/08/xop/include" href="cid:46834192-2caa-4016-ab11-8a48e0cbeb6c-194@urn%3Aus%3Agov%3Atreasury%3Airs%3Acommon"/>
        </ns2:BulkExchangeFile>
    </ACABulkReqTrnsmtStsRespGrpDtl>
</ns6:ACABulkRequestTransmitterStatusDetailResponse>

这是我使用的所有 C# 代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Xml;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            using (TextReader reader = File.OpenText(@"C:\Projects\Prototypes\irsAcaClient\ConsoleApp1\XMLFile1.xml"))
            {
                string xml = reader.ReadToEnd();
                var o = Deserialize<ACABulkRequestTransmitterStatusDetailResponse>(xml);
            }
        }

        /// <summary>
        /// deserializes the xml string into an object
        /// </summary>
        /// <param name="xmlString"></param>
        /// <returns></returns>
        public static T Deserialize<T>(string xmlString) where T : class
        {
            //if the string is empty,just return null
            if (xmlString.Length <= 0)
            {
                return null;
            }

            //create a serializer
            var serializer = new System.Xml.Serialization.XmlSerializer(typeof(T));
            T output;
            //create the reader that the serializer will read from,passing it the string
            using (var reader = new System.IO.StringReader(xmlString))
            {
                //rebuild the list object
                output = (T)serializer.Deserialize(reader);
            }
            //return the list
            return output;
        }
    }

谁能告诉我我做错了什么？谢谢。

解决方法

我认为这里有很多问题，更具体地说是 XML 的生成代码。

在 Visual Studio 中，我创建了一个新类并复制了您的 XML 内容并使用了编辑 -> 选择性粘贴 -> 将 XML 粘贴为类。

这是该练习生成的代码：

使用您的 Deserialize 方法和这个新类，我能够成功解析您的 XML 文件。

我会使用这个类与您自己的生成代码进行比较，看看主要区别在哪里。除非您有空间替换生成的代码？

我发现的第一个是需要将 ACABulkRequestTransmitterStatusDetailResponse 部分类上方的属性修改为：

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml","4.8.4084.0")]
    [System.SerializableAttribute()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true,IsNullable = false)]

希望这对您有所帮助。

我发现了两个问题：

  1. 更改如下： 从 ： [System.Xml.Serialization.XmlTypeAttribute(Namespace = "urn:us:gov:treasury:irs:ext:aca:air:ty20")] 到 ： [XmlRoot(Namespace = "urn:us:gov:treasury:irs:msg:irstransmitterstatusrequest")]

  2. 我更新了这部分代码

         private byte[] BulkExchangeFileType;

     /// <remarks/>
     /// 
     //changed to string from bytes.
     [System.Xml.Serialization.XmlElementAttribute(Namespace = "urn:us:gov:treasury:irs:common")]
     public object BulkExchangeFile
     {
         get
         {
             return Encoding.UTF8.GetString(this.BulkExchangeFileType);
         }
         set
         {
             this.BulkExchangeFileType = Encoding.UTF8.GetBytes(value.ToString());
             this.RaisePropertyChanged("BulkExchangeFile");
         }
     }
