我正在使用 Realex XML API 使用此处找到的 GitHub .Net 库向 MPI 服务器发送 3D 安全注册请求： https ://github.com/JonCanning/RealEx.NET

身份验证过程的前两个步骤对于 3D 安全测试卡 4012001037141112 运行良好，这应该会导致成功的 3D 安全身份验证，但是在尝试反序列化 .Net 类下的 XML 时，ThreeDSecure 永远不会被填充并且始终为空，尽管相应地填充 XML：

<response timestamp="20160830142152">
  <merchantid>*****</merchantid>
  <account>internet</account>
  <orderid>92f669c7-6fb3-43e0-bfb9-8f62aca128cf</orderid>
  <authcode />
  <result>00</result>
  <message>Authentication Successful</message>
  <pasref />
  <timetaken>0</timetaken>
  <authtimetaken>0</authtimetaken>
  <threedsecure>
    <status>Y</status>
    <eci>5</eci>
    <cavv>AAACBDlZYkmAggkgJVliAAAAAAA=</cavv>
    <xid>ZFD6gQMih8V5gzA3q/XODcrx8N8=</xid>
    <algorithm>2</algorithm>
  </threedsecure>
  <sha1hash>a9800768d3e683de4cf074195884d67d29f79189</sha1hash>
</response>

.Net 类的代码如下：

namespace RealEx
{
    [XmlRoot("response")]
    public class RealExResponse
    {
        [XmlElement("result")]
        public string Result { get; set; }
        [XmlElement("message")]
        public string Message { get; set; }
        [XmlElement("pasref")]
        public string PasRef { get; set; }
        [XmlElement("authcode")]
        public string AuthCode { get; set; }
        [XmlElement("pareq")]
        public string PaReq { get; set; }
        [XmlElement("enrolled")]
        public string Enrolled { get; set; }
        [XmlElement("xid")]
        public string Xid { get; set; }
        [XmlElement("orderid")]
        public string OrderId { get; set; }
        [XmlElement("sha1hash")]
        public string Sha1Hash { get; set; }
        [XmlElement("merchantid")]
        public string MerchantId { get; set; }
        [XmlElement("account")]
        public string Account { get; set; }
        [XmlElement("timetaken")]
        public string TimeTaken { get; set; }
        [XmlElement("authtimetaken")]
        public string AuthTimeTaken { get; set; }
        [XmlElement("url")]
        public string Url { get; set; }
        [XmlAttribute("timestamp")]
        public string TimeStamp { get; set; }
        [XmlElement("threedsecure")]
        public ThreeDSecure ThreeDSecure { get; set; }
        [XmlElement("cvnresult")]
        public string CvnResult { get; set; }
        [XmlElement("avspostcoderesponse")]
        public string AvsPostcodeResponse { get; set; }
        [XmlElement("avsaddressresponse")]
        public string AvsAddressResponse { get; set; }
        [XmlElement("batchid")]
        public string BatchId { get; set; }
        [XmlElement("cardissuer")]
        public CardIssuer CardIssuer { get; set; }

        internal static RealExResponse Deserialize(string xml)
        {
            return new XmlSerializer(typeof(RealExResponse)).Deserialize(XDocument.Parse(xml).CreateReader()) as RealExResponse;
        }
    }
}


namespace RealEx
{
    public class ThreeDSecure
    {
        public string Status { get; set; }
        public string Eci { get; set; }
        public string Cavv { get; set; }
        public string Xid { get; set; }
        public string Algorithm { get; set; }
    }
}

namespace RealEx
{
    public class RealEx3DAuthRequest : RealExAuthRequest
    {
        public RealEx3DAuthRequest(string secret, string merchantId, string account, string orderId, Amount amount, Card card, TssInfo tssInfo, ThreeDSecure threeDSecure, bool autoSettle, string custNum, string prodId, string varRef, Comments comments)
            : base(secret, merchantId, account, orderId, amount, card, tssInfo, autoSettle, custNum, prodId, varRef, comments)
        {
            Mpi = new Mpi(threeDSecure.Cavv, threeDSecure.Xid, threeDSecure.Eci);
        }
        public Mpi Mpi { get; private set; }
    }
}

我不明白为什么在正确编写所有其他属性时，响应中收到的信息没有写入类中，任何人都可以帮助我理解这个问题吗？

您的ThreeDSecure属性与 XML 中的名称不匹配。更改名称以匹配（即更改大小写）或添加适当的属性：

public class ThreeDSecure
{
    [XmlElement("status")]
    public string Status { get; set; }
    [XmlElement("eci")]
    public string Eci { get; set; }
    [XmlElement("cavv")]
    public string Cavv { get; set; }
    [XmlElement("xid")]
    public string Xid { get; set; }
    [XmlElement("algorithm")]
    public string Algorithm { get; set; }
}

顺便说一句，在反序列化之前无需将 XML 解析为 DOM。只需使用 aStringReader代替：

using (var reader = new StringReader(xml))
{
    return (RealExResponse)new XmlSerializer(typeof(RealExResponse)).Deserialize(reader);
}
