嵌套项目的 XmlArrayItem 反序列化错误

Question

我对序列化完全陌生，非常感谢任何帮助。

我在反序列化从通过 WSDL.exe 创建的代理类收到的响应消息时遇到问题。我相信问题在于我正在使用 XmlArrayItem，其中包含嵌套项目。

而不是得到：

<results xmlns="urn:partner.soap.company.com">
    <result>
        <created>false</created>
        <id>0018000000ZqV8DAAV</id>
        <success>true</success>
     </result>
     <result>
        <created>false</created>
        <id>0018000000ZqVMAAA3</id>
        <success>true</success>
     </result>
</results>

我在代码中收到以下内容：

created(0):false
id(0): false 0018000000ZqV8DAAV
success(0):false 0018000000ZqV8DAAVtrue

created(1):false 0018000000ZqV8DAAVtruefalse
id(1): false 0018000000ZqV8DAAVtruefalse0018000000ZqVMAAA3
success(1): false 0018000000ZqV8DAAVtruefalse0018000000ZqVMAAA3true

看起来好像响应只是不断附加消息的下一部分，而不清除之前发生的任何内容。

这是调用 Web 服务的主要函数：

 <System.Web.Services.Protocols.SoapDocumentMethodAttribute("", Use:=System.Web.Services.Description.SoapBindingUse.Literal, _
    ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Bare)> _
    Public Function Provide_Service(<System.Xml.Serialization.XmlElement([Namespace]:="http://www.company.com/connectors/request/129/")> _
    ByVal USIUpdates As USIUpdates) As _
    <System.Xml.Serialization.XmlArray("results", IsNullable:=False, [Namespace]:="urn:partner.soap.sforce.com"), _
    System.Xml.Serialization.XmlArrayItem("result", IsNullable:=False)> UpsertResult()

        Dim results() As Object = Me.Invoke("Provide_Service", New Object() {USIUpdates})
        Return CType(results(0), UpsertResult())
    End Function

这是生成响应的类：

<System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42"), _
 System.SerializableAttribute(), _
 System.Diagnostics.DebuggerStepThroughAttribute(), _
 System.ComponentModel.DesignerCategoryAttribute("code"), _
 System.Xml.Serialization.XmlTypeAttribute([Namespace]:="urn:partner.soap.company.com")> _
Partial Public Class UpsertResult

    'Public ReturnResponseItems As [ResponseItems]

    Private createdField As String

    Private errorsField() As [Error]

    Private idField As String

    Private successField As String

    '''<remarks/>
    Public Property created() As String
        Get
            Return Me.createdField
        End Get
        Set(ByVal value As String)
            Me.createdField = value
        End Set
    End Property

    '''<remarks/>
    <System.Xml.Serialization.XmlElementAttribute("errors")> _
    Public Property errors() As [Error]()
        Get
            Return Me.errorsField
        End Get
        Set(ByVal value As [Error]())
            Me.errorsField = value
        End Set
    End Property

    '''<remarks/>
    <XmlElementAttribute(isnullable:=True)> _
    Public Property id() As String
        Get
            Return Me.idField
        End Get
        Set(ByVal value As String)
            Me.idField = value
        End Set
    End Property

    '''<remarks/>
    Public Property success() As String
        Get
            Return Me.successField
        End Get
        Set(ByVal value As String)
            Me.successField = value
        End Set
    End Property
End Class

如果您有任何有关如何处理此问题的想法或建议，我将不胜感激。

Answer 1

如果其他人遇到这个问题，这里是解决方案。由于某种原因，当 WSDL.exe 运行时，XMLArrayItemAttribute 没有正确指向包含其中数组的类。

因此，需要将以下内容添加到主函数中的 XMLArrayItemAttribute：

Type:=GetType(UpsertResult)

，然后如下所示：

System.Xml.Serialization.XmlArrayItemAttribute("result", IsNullable:=False，类型：=GetType(UpsertResult))
