使用嵌套命名空间反序列化 XML 文件时出现问题

Question

我有以下 XML 文件（摘录）：

<AutoindexBundle xmlns:i="...www.w3.org/2001/XMLSchema-instance" xmlns="...dev.mysite.com/settings/settingsExchange">
    <Autoindex xmlns:d2p1="...dev.mysite.com/settings/workflows/autoindex">
        <Header xmlns="...//dev.mysite.com/settings/bpsprocesses/common">
            <Guid xmlns="...//dev.mysite.com/settings/interop">0a3b7b31-907a-40bf-b55f-747046dc7ea2</Guid>
            <ID xmlns="...//dev.mysite.com/settings/interop">413</ID>
            <Name xmlns="...//dev.mysite.com/settings/interop">SD_CLEAR_STATUS</Name>
            <Description>Löscht die Einträge im Statusfeld</Description>
        </Header>
        <d2p1:AIMatchOptionSettings>
            <d2p1:MatchCodes>
...

例如，我想反序列化此文件以获得“Header.Name”下的信息。我已经在互联网上查看了许多示例，但不知何故它们并不全部与我的源文件匹配。

我首先使用“插入特殊”功能在 VB.NET 中创建一个类，并将其保存在名为“AutoindesBundle”的模块中。以下是摘录：

然后我尝试从 Header 元素中读取信息：

Private Sub DeserializeObject(ByVal filename As String)
        Console.WriteLine("Reading with XmlReader")
        Dim serializer As New XmlSerializer(GetType(AutoindexBundle.Header))
        Dim fs As New FileStream(filename, FileMode.Open)
        Dim reader As XmlReader = XmlReader.Create(fs)
        Dim test As AutoindexBundle.Header
        test = CType(serializer.Deserialize(reader), AutoindexBundle.Header)
        fs.Close()
        Console.Write(test.Guid & ControlChars.Tab &
                      test.ID & ControlChars.Tab &
                      test.Name & ControlChars.Tab &
                      test.Description & ControlChars.Tab)
    End Sub

但不幸的是，我在 test = CType(.... 行中收到以下错误消息： System.InvalidOperationException:“XML 文档 (1, 40) 中存在错误。” 内部 Ausnahme 1： InvalidOperationException：不是预期的。

我在这里做错了什么或者我必须改变什么才能使这项工作正常进行？
