【问题描述】：

我正在尝试反序列化 XML 。 示例 XML 如下所示

 <?xml version="1.0" ?> 
 <TRANSACTION_RESPONSE>
    <TRANSACTION>
        <TRANSACTION_ID>25429</TRANSACTION_ID> 
        <MERCHANT_ACC_NO>02700701354375000964</MERCHANT_ACC_NO> 
        <TXN_STATUS>F</TXN_STATUS> 
        <TXN_SIGNATURE>a16af68d4c3e2280e44bd7c2c23f2af6cb1f0e5a28c266ea741608e72b1a5e4224da5b975909cc43c53b6c0f7f1bbf0820269caa3e350dd1812484edc499b279</TXN_SIGNATURE> 
        <TXN_SIGNATURE2>B1684258EA112C8B5BA51F73CDA9864D1BB98E04F5A78B67A3E539BEF96CCF4D16CFF6B9E04818B50E855E0783BB075309D112CA596BDC49F9738C4BF3AA1FB4</TXN_SIGNATURE2> 
        <TRAN_DATE>29-09-2015 07:36:59</TRAN_DATE> 
        <MERCHANT_TRANID>150929093703RUDZMX4</MERCHANT_TRANID> 
        <RESPONSE_CODE>9967</RESPONSE_CODE> 
        <RESPONSE_DESC>Bank rejected transaction!</RESPONSE_DESC> 
        <CUSTOMER_ID>RUDZMX</CUSTOMER_ID> 
        <AUTH_ID /> 
        <AUTH_DATE /> 
        <CAPTURE_DATE /> 
        <SALES_DATE /> 
        <VOID_REV_DATE /> 
        <REFUND_DATE /> 
        <REFUND_AMOUNT>0.00</REFUND_AMOUNT> 
    </TRANSACTION>
  </TRANSACTION_RESPONSE>  

下面是类

[XmlType("TRANSACTION_RESPONSE")]

public class BankQueryResponse

    [XmlElement("TRANSACTION_ID")]
    public string TransactionId  get; set; 

    [XmlElement("MERCHANT_ACC_NO")]
    public string MerchantAccNo  get; set; 

    [XmlElement("TXN_SIGNATURE")]
    public string TxnSignature  get; set; 

    [XmlElement("TRAN_DATE")]
    public DateTime TranDate  get; set; 

    [XmlElement("TXN_STATUS")]
    public string TxnStatus  get; set; 


    [XmlElement("REFUND_DATE")]
    public DateTime RefundDate  get; set; 

    [XmlElement("RESPONSE_CODE")]
    public string ResponseCode  get; set; 


    [XmlElement("RESPONSE_DESC")]
    public string ResponseDesc  get; set; 

    [XmlAttribute("MERCHANT_TRANID")]
    public string MerchantTranId  get; set; 

反序列化代码为

BankQueryResponse result = new BankQueryResponse();
if(!string.IsNullOrEmpty(responseData))

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

    using(TextReader xmlreader = new StringReader(responseData))
    
        result = (BankQueryResponse) serializer.Deserialize(xmlreader);
    

我将结果中的所有值都设为 null 。我不确定是什么原因。有人可以解决这个问题。我在反序列化时是否遗漏了什么

【问题讨论】：

TRANSACTION 级别丢失了。

【参考方案1】：

你应该像这样修改代码

[XmlType("TRANSACTION_RESPONSE")]
public class TransactionResponse

    [XmlElement("TRANSACTION")]
    public BankQueryResponse Response  get; set; 

会变成这样的

public class BankQueryResponse

    [XmlElement("TRANSACTION_ID")]
    public string TransactionId  get; set; 

    [XmlElement("MERCHANT_ACC_NO")]
    public string MerchantAccNo  get; set; 

    [XmlElement("TXN_SIGNATURE")]
    public string TxnSignature  get; set; 

    [XmlElement("TRAN_DATE")]
    public DateTime TranDate  get; set; 

    [XmlElement("TXN_STATUS")]
    public string TxnStatus  get; set; 


    [XmlElement("REFUND_DATE")]
    public DateTime RefundDate  get; set; 

    [XmlElement("RESPONSE_CODE")]
    public string ResponseCode  get; set; 


    [XmlElement("RESPONSE_DESC")]
    public string ResponseDesc  get; set; 

    [XmlAttribute("MERCHANT_TRANID")]
    public string MerchantTranId  get; set; 

反序列化代码是这样的

TransactionResponse result = new TransactionResponse();
if(!string.IsNullOrEmpty(responseData))

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

    using(TextReader xmlreader = new StringReader(responseData))
    
        result = (TransactionResponse) serializer.Deserialize(xmlreader);
    

【讨论】：

谢谢@Mohit。我错过了反序列化中的一级层次结构。你的建议奏效了。

很高兴为您提供帮助:)
