public:
 int GetNodeCount(bool includeSubTrees);
public int GetNodeCount (bool includeSubTrees);
member this.GetNodeCount : bool -> int
Public Function GetNodeCount (includeSubTrees As Boolean) As Integer

Parámetros

includeSubTrees
Boolean

Es true si el recuento resultante incluye todos los nodos de árbol cuya raíz está indirectamente situada en este nodo de árbol; en caso contrario, es false.true if the resulting count includes all tree nodes indirectly rooted at this tree node; otherwise, false.

Devoluciones

Número de nodos de árbol secundarios asignados a la colección de Nodes.The number of child tree nodes assigned to the Nodes collection.

Ejemplos

En el ejemplo de código siguiente PathSeparator se establece la TreeView propiedad de un y se muestra el número de nodos de árbol secundarios TreeNodeCollection SelectedNodecontenidos en de.The following code example sets the PathSeparator property of a TreeView and displays the number of child tree nodes that are contained in the TreeNodeCollection of the SelectedNode. También se muestra el porcentaje del nodo de árbol secundario para el total de nodos de árbol en el control de vista de árbol.The percentage of child tree node to total tree nodes in the tree view control is also displayed. Este ejemplo requiere que Form tenga un Buttoncon y un TreeView control con un TreeNodeCollection que tenga varios TreeNode objetos (preferiblemente con tres o más niveles).This example requires that you have a Form with a Button, and a TreeView control with a TreeNodeCollection that has several TreeNode objects (preferably with three or more levels).

   // Get the count of the child tree nodes contained in the SelectedNode.
   int myNodeCount = myTreeView->SelectedNode->GetNodeCount( true );
   Decimal myChildPercentage = ((Decimal)myNodeCount / (Decimal)myTreeView->GetNodeCount( true )) * 100;

   // Display the tree node path and the number of child nodes it and the tree view have.
   MessageBox::Show( String::Concat( "The '", myTreeView->SelectedNode->FullPath, "' node has ", myNodeCount, " child nodes.\nThat is ", String::Format( "{0:###.##}", myChildPercentage ), "% of the total tree nodes in the tree view control." ) );
