反序列化 XML 给我 null 而不是对象

Deserializing XML gives me null instead of the object

这是我的 XML:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE paymentService PUBLIC "-//WorldPay//DTD WorldPay PaymentService v1//EN"
                                "http://dtd.worldpay.com/paymentService_v1.dtd">
<paymentService version="1.4" merchantCode="ABC">
    <reply>
        <error code="4">
            <![CDATA[Security violation]]>
        </error>
    </reply>
</paymentService>

我将其反序列化为 类 使用他们提供的 XSD 创建的:

var responseStreamReader = new StreamReader(response.GetResponseStream());

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "paymentService";

XmlSerializer mySerializer = new XmlSerializer(typeof(paymentService), xRoot);

var someResponse = (paymentService) mySerializer.Deserialize(responseStreamReader);

它反序列化了 paymentService、version、merchantCode,但是 Item 属性 是 null

这是架构的一部分:

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.33440")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://tempuri.org/worldpa
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://tempuri.org/worldpay", IsNullable = false
public partial class paymentService
{

    private object itemField;

    private paymentServiceVersion versionField;

    private string merchantCodeField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("inquiry", typeof (inquiry))]
    [System.Xml.Serialization.XmlElementAttribute("modify", typeof (modify))]
    [System.Xml.Serialization.XmlElementAttribute("notify", typeof (notify))]
    [System.Xml.Serialization.XmlElementAttribute("reply", typeof (reply))]
    [System.Xml.Serialization.XmlElementAttribute("submit", typeof (submit))]
    [System.Xml.Serialization.XmlElementAttribute("verify", typeof (verify))]
    public object Item
    {
        get { return this.itemField; }
        set { this.itemField = value; }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlAttribute]
    public paymentServiceVersion version
    {
        get { return this.versionField; }
        set { this.versionField = value; }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlAttribute(DataType = "NMTOKEN")]
    public string merchantCode
    {
        get { return this.merchantCodeField; }
        set { this.merchantCodeField = value; }
    }
}

我希望项目是一个 reply 对象。

我可能做错了什么?

我已经解决了这个问题,可能不是最好的方式,但为了其他人的利益..

我刚刚从所有内容中删除了命名空间。

我的模式是用 XSD.exe 生成的,我删除了对 Namespace = "http://tempuri.org/worldpay" 的所有引用,这修复了它。这也意味着我不必乱用 XmlRootAttribute。
