    Implements ICollection, IEnumerable
'Usage
Dim instance As ContextNodeBaseCollection

public class ContextNodeBaseCollection : ICollection,

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie eine ContextNodeBaseCollection vom InkAnalyzerBase-Objekt aus durchlaufen wird. Die FindNodesOfType-Methode eines InkAnalyzerBase-Objekts mit dem Namen theInkAnalyzerBase. Das Beispiel durchläuft alle Line-Knoten. Wenn zwei Freihandwortknoten mit demselben Wort vorhanden sind, werden sie rot markiert.

' If two identical ink words occur next to each other, mark them as red.
' Note: This doesn't actually look for pairs that go across two lines.
Dim lines As ContextNodeBaseCollection = _
    theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line)

For Each lineNode As ContextNodeBase In lines

    Dim previousWord As ContextNodeBase = Nothing
    Dim previousWordRecognizedString As String = ""

    For Each inkWord As ContextNodeBase In _
        theInkAnalyzerBase.FindNodesOfType(ContextNodeTypeBase.InkWord, lineNode)

        Dim inkWordRecognizedString As String = ""

        If inkWord.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) Then
            inkWordRecognizedString = _
                CType(inkWord.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), String)
        End If

        ' TODO: I think I can get rid of this and just assign the previous string 
        ' to the current string
        If Not previousWord Is Nothing Then

            previousWordRecognizedString = _
            CType(previousWord.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), String)

        End If

        If previousWordRecognizedString <> "" Then

            Dim previousWordStrokes As Strokes = theInk.CreateStrokes(previousWord.GetStrokeIds())
            Dim inkWordStrokes As Strokes = theInk.CreateStrokes(previousWord.GetStrokeIds())
