复杂的 XML 反序列化答案

【问题标题】：Complex XML deserialization复杂的 XML 反序列化
【发布时间】：2014-07-23 21:43:39
【问题描述】：

我正在尝试反序列化一个复杂的 XML 文件。我的主类是结构化的，因此它可以获取第一个子节点中的所有信息，我什至拥有它，以便我可以获得两层深的ClientName。但是，除此之外的任何东西似乎都不起作用。我得到一个计数为 1 的列表项，但列表中没有信息。

我的OrderTaxes 和OrderTransactions 列表返回Count = 1，但所有字段均为空。

我很肯定这是我的班级结构的问题，非常感谢任何有助于纠正这个问题的帮助。

这是 XML：

<OrderDetail>
    <MessageTypeCode>82540</MessageTypeCode>
    <OrderDetailId>59339463</OrderDetailId>
    <ClientInfo>
        <ClientName>LenderName will appear here</ClientName>
    </ClientInfo>
    <OrderTaxes>
        <OrderTax>
            <TaxId>9202225</TaxId>
        </OrderTax>
    </OrderTaxes>
    <OrderTransactions>
        <OrderTransaction>
            <LoanAmount/>
            <Title>
                <TitleVendors>
                    <TitleVendor>
                        <VendorInstructions>blah blah blah blah .</VendorInstructions>
                        <VendorServices>
                            <TitleVendorService>
                                <TitleVendorServiceId>6615159</TitleVendorServiceId>
                                <ServiceCode>1OWNER</ServiceCode>
                                <CustomVendorInstructions>blah blah blah blah blah </CustomVendorInstructions>
                            </TitleVendorService>
                        </VendorServices>
                    </TitleVendor>
                </TitleVendors>
            </Title>
        </OrderTransaction>
    </OrderTransactions>
</OrderDetail>

这是课程：

namespace TSIxmlParser
{
    [XmlRoot("OrderDetail")]
    public class OrderData
    {
        [XmlElement("MessageTypeCode")]
        public string MessageTypeCode { get; set; }

        [XmlElement("OrderDetailId")]
        public string OrderNumber { get; set; }

        [XmlElement("ClientInfo")]
        public List<ClientInfo> ClientInfos = new List<ClientInfo>();

        [XmlArray("OrderTaxes")]
        [XmlArrayItem("OrderTax")]
        public List<OrderTax> OrderTaxes = new List<OrderTax>();

        [XmlArray("OrderTransactions")]
        [XmlArrayItem("OrderTransaction")]
        public List<OrderTransaction> OrderTransactions = new List<OrderTransaction>();
    }

    public class ClientInfo
    {
        [XmlElement("ClientName")]
        public string ClientName { get; set; }
    }

    public class OrderTax
    {
        [XmlElement("TaxId")]
        public string TaxId { get; set; }
    }

    public class OrderTransaction
    {
        [XmlElement("LoanAmount")]
        public string LoanAmount { get; set; }

        [XmlArray("Title")]
        [XmlArrayItem("TitleVendors")]
        public List<Title> Titles { get; set; }
    }

    public class Title
    {       
        [XmlArrayItem("TitleVendors")]        
        public List<TitleVendors> TitleVendors { get; set; }
    }

    public class TitleVendors
    {
        [XmlArray("TitleVendor")]
        public List<TitleVendor> TitleVendor { get; set; } 
    }

    public class TitleVendor
    {
        [XmlElement("VendorInstructions")]
        public string VendorInstructions { get; set; }

        [XmlArray("VendorServices")]
        [XmlArrayItem("TitleVendorService")]
        public List<TitleVendorService> VendorServices { get; set; }
    }

    public class TitleVendorService
    {
        [XmlElement("TitleVendorServiceId")]
        public string TitleVendorServiceId { get; set; }
        [XmlElement("ServiceCode")]
        public string ServiceCode { get; set; }
        [XmlElement("CustomVendorInstructions")]
        public string CustomVendorInstructions { get; set; }
    }
}

【问题讨论】：

您打算清除标签前的-s，还是应该在发布前自行测试我们的答案？
我不知道这是一个要求。
不，这不是必需的。但是准备一个易于阅读（并且易于复制和粘贴）的答案表明您的努力和对读者的尊重。
有道理，我也想知道为什么我被否决了。这是我的第二个被无缘无故否决的问题。我觉得我的两个问题都是中肯的，有利于学习过程。

【解决方案1】：

.NET SDK 为此提供了一个很好的工具。 XML 计划定义工具 (csd.exe)。

我使用您的 XML 运行了一个示例，向您展示它是否有效。

首先，我将您的 XML 保存到我的桌面上的一个名为“sample.xml”的文件中
我以管理员身份打开了 VS 2012 命令提示符。
在命令提示符中，我导航到安装 SDK 的目录。对我来说，它安装在这里（可能与各种操作系统或 VS 版本不同）：

C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools
我运行以下命令为您的 XML 创建 XSD。（期望 sample.xsd 出现在桌面上）

xsd "c:\users\glenn\desktop\sample.xml" /outputdir:"c:\users\glenn\desktop"
我运行以下命令从生成的 XSD 文件创建 CSharp 文件。

xsd "c:\users\glenn\desktop\sample.xsd" /classes /outputdir:"c:\users\glenn\desktop"

不包括 cmets，这是为您的 XML 架构自定义生成的 CSharp 文件。还有其他选项可以设置命名空间和类型名。有关详细信息，请查看上面的文章。

希望这会有所帮助！

【讨论】：

这就像你说的那样工作，遗憾的是它一直在 XmlSerializer() 上给我错误。 ` 无法生成临时类 (result=1)。` 错误 CS0030：无法将类型“OrderDetailClientInfoClientName[]”转换为“OrderDetailClientInfoClientName”错误 CS0030：无法将类型“OrderDetailOrderTaxesOrderTaxTaxId[][]”转换为“OrderDetailOrderTaxesOrderTaxTaxId[]”错误 CS0030 : 无法将类型 'OrderDetailOrderDocumentsOrderDocumentDocumentInformation[][]' 转换为 'OrderDetailOrderDocumentsOrderDocumentDocumentInformation[]' ...等等等等

【解决方案2】：

尝试在相应的属性上使用 XmlArray 和 XmlArrayItem。

[XmlArray("OrderTaxes")]
[XmlArrayItem("OrderTax")]
public List<OrderTax> OrderTaxes = new List<OrderTax>();

和

[XmlArray("OrderTransactions")]
[XmlArrayItem("OrderTransaction")]
public List<OrderTransaction> OrderTransactions = new List<OrderTransaction>();

这样，序列化程序将知道这些将被视为集合，并知道如何查找特定项目。

除了这两个之外，我想说的是，无论您在哪里定义元素列表，都应该使用这种方法。 TitleVendors 很可能需要类似的东西。

【讨论】：

您的回答对我 90% 的问题有效。现在我无法通过TitleVendors 列表。我的 VendorInstructions 始终为空，而我的 VendorServices 的计数 = 0。
@MaylorTaylor，我认为您的 OrderTransaction 应该公开 Title 类型的 Title 属性，而不是 List 类型。除此之外，TitleVendor 应该公开一个 List<titlevendorservice>。我建议扁平化内部类层次结构，以便更清晰地遵循反序列化流程。</titlevendorservice>

【解决方案3】：

好吧，我不确定你是否想要这个（反序列化 XML 的原始转储）：

{
    MessageTypeCode: 82540,
    OrderDetailId: 59339463,
    ClientInfo: 
    {
        ClientName: LenderName will appear here
    },
    OrderTaxes: 
    {
        OrderTax: 
        {
            TaxId: 9202225
        }
    },
    OrderTransactions: 
    {
        OrderTransaction: 
        {
            LoanAmount: {},
            Title: 
            {
                TitleVendors: 
                {
                    TitleVendor: 
                    {
                        VendorInstructions: blah blah blah blah .,
                        VendorServices: 
                        {
                            TitleVendorService: 
                            {
                                TitleVendorServiceId: 6615159,
                                ServiceCode: 1OWNER,
                                CustomVendorInstructions: blah blah blah blah blah 
                            }
                        }
                    }
                }
            }
        }
    }
}

【讨论】：

我不知道这个“将 XML 粘贴到类”功能。您必须将 TargetFramework 设置为 .Net 4.5，该功能才会出现在 EDIT > Paste Special 菜单下。（完成此操作后，您可以切换回框架）
我在 Visual Studio for Web 中找到了它：P

【解决方案4】：

由于这仍然是开放的，我想我会快速回答，适合XmlSerializer。在制作课程时，我假设了一个类似这样的模式：

<Foo>
    <Bars>
        <Bar>

表示“Foo”类包含“Bar”类的实例列表。像这样的模式：

<Foo>
    <Bar>

表示“Foo”类包含对“Bar”类实例的单个引用。因此，您的“OrderTransaction”中应该只有一个“Title”，而不是它们的列表：

public class OrderDetail
{
    public string MessageTypeCode { get; set; }
    public string OrderDetailId { get; set; }
    public ClientInfo ClientInfo { get; set; }

    public List<OrderTax> OrderTaxes { get; set; }

    public List<OrderTransaction> OrderTransactions { get; set; }
}

public class OrderTransaction
{
    public string LoanAmount { get; set; }
    public Title Title { get; set; }
}

public class Title
{
    public List<TitleVendor> TitleVendors { get; set; }
}

public class TitleVendor
{
    public string VendorInstructions { get; set; }

    public List<TitleVendorService> VendorServices { get; set; }
}

public class TitleVendorService
{
    public string TitleVendorServiceId { get; set; }
    public string ServiceCode { get; set; }
    public string CustomVendorInstructions { get; set; }
}

public class ClientInfo
{
    public string ClientName { get; set; }
}

public class OrderTax
{
    public string TaxId { get; set; }
}

实际上不需要任何与 XML 相关的修饰。 XmlElement 和 XmlArray 仅在您想要覆盖 XmlSerializer 的默认选项时才需要，例如重命名元素或处理具有多态元素的数组。如果您想清楚起见，或者为了防止以后重命名该属性，您可以放置它们，但为了简单起见，我没有这样做。

这是测试设置。我从您的字符串中创建了一个“OrderDetail”实例，然后将其重新序列化为 XML，然后将原始和重写的 XML 保存为文件并在命令提示符窗口中对它们进行比较：

public static class TestOrderDetail
{
    public static string TestString =

@"<OrderDetail> <MessageTypeCode>82540</MessageTypeCode> <OrderDetailId>59339463</OrderDetailId> <ClientInfo> <ClientName>LenderName will appear here</ClientName> </ClientInfo> <OrderTaxes> <OrderTax> <TaxId>9202225</TaxId> </OrderTax> </OrderTaxes> <OrderTransactions> <OrderTransaction> <LoanAmount/> <Title> <TitleVendors> <TitleVendor> <VendorInstructions>blah blah blah blah .</VendorInstructions> <VendorServices> <TitleVendorService> <TitleVendorServiceId>6615159</TitleVendorServiceId> <ServiceCode>1OWNER</ServiceCode> <CustomVendorInstructions>blah blah blah blah blah </CustomVendorInstructions> </TitleVendorService> </VendorServices> </TitleVendor> </TitleVendors> </Title> </OrderTransaction> </OrderTransactions> </OrderDetail>";

    public static void Test()
    {
        try
        {
            XmlSerializer serializer = new XmlSerializer(typeof(OrderDetail));
            OrderDetail orderDetail = (OrderDetail)serializer.Deserialize(new StringReader(TestString));

            string newTestString = TestWrite(serializer, orderDetail);

            var guid = DateTime.Now.Ticks;
            var path = Path.GetTempPath();
            var file1 = path + Path.DirectorySeparatorChar + "OldOrderDetail_" + guid.ToString() + ".xml";
            var file2 = path + Path.DirectorySeparatorChar + "NewOrderDetail_" + guid.ToString() + ".xml";
            File.WriteAllText(file1, TestString);
            File.WriteAllText(file2, newTestString);
        }
        catch (Exception e)
        {
            Debug.Assert(false, e.ToString());
        }
    }

    private static string TestWrite(XmlSerializer serializer, OrderDetail orderDetail)
    {
        using (var textWriter = new StringWriter())
        {
            XmlWriterSettings settings = new XmlWriterSettings();
            settings.OmitXmlDeclaration = true; // For testing purposes, disable the xml version and encoding declarations.
            settings.Indent = true;
            settings.IndentChars = "    "; // The indentation used in the test string.
            using (XmlWriter xmlWriter = XmlWriter.Create(textWriter, settings))
            {
                XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
                ns.Add("", ""); // For testing purposes, disable the xmlns:xsi and xmlns:xsd lines, which were not in the test string.
                serializer.Serialize(xmlWriter, orderDetail, ns);
            }
            return textWriter.ToString();
        }
    }
}

这是新旧 XML 文件的差异结果：

diff OldOrderDetail_635420738451748332.xml NewOrderDetail_635420738451748332.xml
14c14
<             <LoanAmount/>
---
>             <LoanAmount />

除了在空的“LoanAmount”元素中插入额外的格式化空间之外，没有任何区别。

【讨论】：

【解决方案5】：

顺便说一句，XmlSerializer 和 DataContractSerializer 完全不同。根据您的示例，您需要使用 XmlSeralizer（不是 DataContractSerializer）。

【讨论】：

【解决方案6】：

这是我目前所拥有的。此代码生成以下结构：

-OrderTransactions (Count = 1)
   - Loan Amount = ""
   - Titles (Count = 1)
       -TitleVendors (Count = 1)
           - VendorInstructions = null
           - VendorServices (Count = 0)

它似乎看到了 TitleVendors 中的节点，但它没有获取信息。

<OrderTransactions>
  <OrderTransaction>
    <LoanAmount /> --this may be NULL - this should not cause the message to fail. 
    <Title>
      <TitleVendors>
         <TitleVendor>
            <VendorInstructions>Endorsements required: EPA, COMP, PUD. **Attention Abstractor: THIS IS A VA LOAN** **Attention Abstractor: If a PRIVATE ROAD EASEMENT exists, please provide any information and copies along with the abstract.</VendorInstructions> 
         <VendorServices>
           <TitleVendorService>

           </TitleVendorService>
        </VendorServices>
