Sintaxis

'Declaración
Public ReadOnly Property SubNodes As ContextNodeBaseCollection
'Uso
Dim instance As ContextNodeBase
Dim value As ContextNodeBaseCollection

value = instance.SubNodes

public ContextNodeBaseCollection SubNodes { get; }

public:
property ContextNodeBaseCollection^ SubNodes {
    ContextNodeBaseCollection^ get ();

public function get SubNodes () : ContextNodeBaseCollection

Valor de propiedad

Tipo: System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
Elementos secundarios directos del objeto ContextNodeBase.

Comentarios

Esto devuelve sólo los elementos secundarios directos, no todos los descendientes.

Ejemplos

Este ejemplo es un método que recorre de forma recursiva un árbol de objetos ContextNodeBase. Utiliza la propiedad SubNodes y rellena System.Windows.Forms.TreeView agregando objetos TreeNode. A continuación, establece su propiedad Text en ToString, agregando el nombre de la forma o cadena reconocida, según corresponda.
