Spazio dei nomi: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Sintassi

'Dichiarazione
Public Sub DeleteSubNode ( _
    node As ContextNodeBase _
)
'Utilizzo
Dim instance As ContextNodeBase
Dim node As ContextNodeBase

instance.DeleteSubNode(node)

public void DeleteSubNode(
    ContextNodeBase node
)

public:
void DeleteSubNode(
    ContextNodeBase^ node
)

public void DeleteSubNode(
    ContextNodeBase node
)

public function DeleteSubNode(
    node : ContextNodeBase
)

Parametri

node
Tipo: System.Windows.Ink.AnalysisCore.ContextNodeBase
Oggetto ContextNodeBase da eliminare.

Note

Se il nodo non è vuoto, viene generata un'eccezione. Se node non è un elemento figlio di questo oggetto ContextNodeBase, viene generata un'eccezione ArgumentException.

Esempi

In questo esempio tutte le righe vengono accettate e inserite nei rispettivi paragrafi. Vengono utilizzate le righe da un oggetto InkAnalyzerBase, denominato theInkAnalyzerBase;, viene creato un nuovo sottonodo di paragrafo per ciascuna riga, le righe vengono riassociate ai nuovi paragrafi come elementi padre e i paragrafi originali vengono eliminati.
