将 XML 数组反序列化为对象

Question

我正在尝试将 XML 字符串反序列化为对象，但出现以下错误：

System.InvalidOperationException：预计不会。

XML:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<epp
    xmlns="urn:ietf:params:xml:ns:epp-1.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0      epp-1.0.xsd">
    <response>
        <result code="1000">
            <msg>Command completed successfully</msg>
        </result>
        <trID>
            <svTRID>20151019181132-1C16AD22-396-0001</svTRID>
        </trID>
    </response>
</epp>

CLASS:

    Imports System.Xml.Serialization

<Serializable(), XmlRoot("epp")>
Public Class EPP

Public Sub New()
    Response = New Response()
End Sub

<XmlElement(ElementName:="response")> _
Public Property Response As Response
End Class

<Serializable()>
Public Class Response

Public Sub New()
    result = New result()
    trID = New trID()
End Sub

<XmlElement(ElementName:="result")> _
Public Property result As result

<XmlElement(ElementName:="trID")> _
Public Property trID As trID
End Class

<Serializable()>
Public Class trID

Public Sub New()
    svTRID = String.Empty
End Sub

<XmlElement(ElementName:="svTRID")> _
Public Property svTRID As String
End Class

<Serializable()>
Public Class result

Public Sub New()
    msg = String.Empty
End Sub

<XmlElement(ElementName:="msg")> _
Public Property msg As String
End Class

代码如下：

Dim r As New EPP
Dim x As New XmlSerializer(r.GetType)

Using s As New StringReader(response.Xml)
    r = x.Deserialize(s)
End Using

"EPP"class有什么问题吗？

您的 XML 有一个默认值 namespace of "urn:ietf:params:xml:ns:epp-1.0" so you need to indicate that your classes are to be serialized into this namespace. The easiest way is to set <XmlRoot(Namespace := "urn:ietf:params:xml:ns:epp-1.0")> for the root class, and <XmlType(Namespace := "urn:ietf:params:xml:ns:epp-1.0")> 其余的：

<XmlRoot("epp", Namespace := "urn:ietf:params:xml:ns:epp-1.0")>
Public Class EPP
    Public Sub New()
        Response = New Response()
    End Sub

    <XmlElement(ElementName:="response")> _
    Public Property Response As Response
End Class

<XmlType(Namespace := "urn:ietf:params:xml:ns:epp-1.0")>
Public Class Response

    Public Sub New()
        result = New result()
        trID = New trID()
    End Sub

    <XmlElement(ElementName:="result")> _
    Public Property result As result

    <XmlElement(ElementName:="trID")> _
    Public Property trID As trID
End Class

<XmlType(Namespace := "urn:ietf:params:xml:ns:epp-1.0")>
Public Class trID
    Public Sub New()
        svTRID = String.Empty
    End Sub

    <XmlElement(ElementName:="svTRID")> _
    Public Property svTRID As String
End Class

<XmlType(Namespace := "urn:ietf:params:xml:ns:epp-1.0")>
Public Class result

    Public Sub New()
        msg = String.Empty
    End Sub

    <XmlElement(ElementName:="msg")> _
    Public Property msg As String
End Class
