将XML数据反序列化为.Net对象会创建对象，但不会加载对象属性的值

Question

我使用以下方法从xml反序列化对象数据。变量 exportExclusions 是使用正确数量的子对象创建的，但它们都具有空值属性。

Public Sub LoadExportExclusionsFromXMLFile()
        Try
            Dim settings As XmlReaderSettings = New XmlReaderSettings()
            settings.DtdProcessing = DtdProcessing.Parse
            exportExclusions = New ExportExclusions()
            Dim reader = XmlReader.Create("../../../ExportExclusions.xml", settings)
            Dim serializer = New System.Xml.Serialization.XmlSerializer(exportExclusions.GetType())
            exportExclusions = DirectCast(serializer.Deserialize(reader), ExportExclusions)
            reader.Close()
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub

这是xml文件
