Tipo: System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
Elementi figlio diretti dell'oggetto ContextNodeBase.

Note

Restituisce solo gli elementi figlio diretti, non tutti i discendenti.

Esempi

Questo esempio è un metodo che attraversa in modo ricorsivo una struttura ad albero di oggetti ContextNodeBase. Utilizza la proprietà SubNodes e compila un oggetto System.Windows.Forms.TreeView aggiungendo oggetti TreeNode. Imposta quindi la proprietà Text su ToString aggiungendo, se necessario, la stringa riconosciuta o il nome della forma.

Private Sub WalkTree(ByVal parentContextNode As ContextNodeBase, ByVal parentTreeNode As TreeNode)

    Dim cNode As ContextNodeBase

    For Each cNode In parentContextNode.SubNodes

        Dim newTNode As New TreeNode(cNode.ToString())

        If cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord AndAlso _
           cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) Then

            newTNode.Text = newTNode.Text + _
                ": " + CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), _
                String)

        ElseIf cNode.Type = System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing AndAlso _
               cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName) Then

            Dim shapeName As String = CType(cNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName), _
                String)

            If shapeName <> "" Then
                newTNode.Text = newTNode.Text + ": " + shapeName
            End If

        End If

        WalkTree(cNode, newTNode)
        parentTreeNode.Nodes.Add(newTNode)

        ' Add the context node as a tag of the tree node
        newTNode.Tag = cNode
    Next cNode

End Sub 'WalkTree

private void WalkTree(
    System.Windows.Ink.AnalysisCore.ContextNodeBase parentContextNode, TreeNode parentTreeNode)
{
    foreach (ContextNodeBase cNode in parentContextNode.SubNodes)
    {
        TreeNode newTNode = new TreeNode(cNode.ToString());
        if ((cNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkWord) &&
             cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString))
        {
            // Get the recognized string
            newTNode.Text += ": " +
                (string)cNode.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString);
        }
        else if ((cNode.Type == System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.InkDrawing) &&
                  cNode.ContainsPropertyData(PropertyGuidsForContextNodesBase.ShapeName))
        {
            newTNode.Text += ": " +
                (string)cNode.GetPropertyData(PropertyGuidsForContextNodesBase.ShapeName);
        }
        WalkTree(cNode, newTNode);
        parentTreeNode.Nodes.Add(newTNode);

        // Add the context node as a tag of the tree node
        newTNode.Tag = cNode;
