Beispiele

Im folgenden Beispiel werden zwei XML-Strukturen erstellt, und anschließend wird diese Methode verwendet, um die Ergebnisse einer Abfrage zu einer dieser Daten hinzuzufügen.

XElement srcTree = new XElement("Root",
    new XElement("Element1", 1),
    new XElement("Element2", 2),
    new XElement("Element3", 3),
    new XElement("Element4", 4),
    new XElement("Element5", 5)
);
XElement xmlTree = new XElement("Root",
    new XElement("NewElement", "Content")
);
xmlTree.Add(
    from el in srcTree.Elements()
    where (int)el >= 3
    select el
);
Console.WriteLine(xmlTree);

Dim srcTree As XElement = _
        <Root>
            <Element1>1</Element1>
            <Element2>2</Element2>
            <Element3>3</Element3>
            <Element4>4</Element4>
            <Element5>5</Element5>
        </Root>
Dim xmlTree As XElement = _
        <Root>
            <NewElement>Content</NewElement>
        </Root>
xmlTree.Add( _
    From el In srcTree.Elements _
    Where CInt(el) >= 3 _
    Select el)
Console.WriteLine(xmlTree)

Dieses Beispiel erzeugt die folgende Ausgabe:

<Root>
  <NewElement>Content</NewElement>
  <Element3>3</Element3>
  <Element4>4</Element4>
  <Element5>5</Element5>
</Root>

Hinweise

Diese Methode fügt den neuen Inhalt nach dem vorhandenen Inhalt der XContainer.

Ausführliche Informationen zu den gültigen Inhalten, die an diese Funktion übergeben werden können, finden Sie unter "Valid Content of XElement" und "XDocument Objects".

Diese Methode löst die Changed Ereignisse und ereignisse Changing aus.
