XmlSerializer-Konstruktor (Type, String)

Initialisiert eine neue Instanz der XmlSerializer-Klasse, die Objekte des angegebenen Typs in XML-Dokumente serialisieren und XML-Dokumente in Objekte des angegebenen Typs deserialisieren kann. Gibt den Standardnamespace für alle XML-Elemente an.

Namespace: System.Xml.Serialization
Assembly: System.Xml (in system.xml.dll)

Syntax

'Declaration
Public Sub New ( _
    type As Type, _
    defaultNamespace As String _
)
'Usage
Dim type As Type
Dim defaultNamespace As String

Dim instance As New XmlSerializer(type, defaultNamespace)

public XmlSerializer (
    Type type,
    string defaultNamespace
)

public:
XmlSerializer (
    Type^ type, 
    String^ defaultNamespace
)

public XmlSerializer (
    Type type, 
    String defaultNamespace
)

public function XmlSerializer (
    type : Type, 
    defaultNamespace : String

Parameter

• type
  Der Objekttyp, den dieser XmlSerializer serialisieren kann.

• defaultNamespace
  Der für alle XML-Elemente zu verwendende Standardnamespace.

Beispiel

Im folgenden Beispiel wird ein XmlSerializer erstellt, der ein einfaches Objekt mit dem Namen Widget serialisiert. Im Beispiel werden vor dem Aufruf der Serialize-Methode verschiedene Eigenschaften des Objekts festgelegt.

Private Sub SerializeObject(ByVal filename As String)
    Dim serializer As New XmlSerializer(GetType(OrderedItem), _
                                          "http://www.cpandl.com")
    
    ' Create an instance of the class to be serialized.
    Dim i As New OrderedItem()
    
    ' Insert code to set property values.
    ' Writing the document requires a TextWriter.
    Dim writer As New StreamWriter(filename)
    ' Serialize the object, and close the TextWriter.
    serializer.Serialize(writer, i)
    writer.Close()
End Sub


Private Sub DeserializeObject(ByVal filename As String)
    Dim serializer As New XmlSerializer(GetType(OrderedItem), _

    Dim fs As New FileStream(filename, FileMode.Open)
    
    ' Declare an object variable of the type to be deserialized.
    Dim i As OrderedItem
