例

次の例では、theInkAnalyzer という名前の InkAnalyzer 内のすべての LineNode オブジェクトをループする方法を示します。各行では、すべての InkWordNode オブジェクトをループし、2 つの連続する InkWordNode オブジェクトが同じ単語として認識された場合は、赤色でマークします。

' 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 ContextNodeCollection = theInkAnalyzer.FindNodesOfType(ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In  lines
    Dim previousWord As InkWordNode = Nothing

    For Each inkWord As InkWordNode In _
        theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord, lineNode)

        If Not (previousWord Is Nothing) AndAlso _
            previousWord.GetRecognizedString() = inkWord.GetRecognizedString() Then

            For Each stroke As Stroke In previousWord.Strokes
                stroke.DrawingAttributes.Color = Colors.Red
            Next stroke

            For Each stroke As Stroke In inkWord.Strokes
                stroke.DrawingAttributes.Color = Colors.Red
            Next stroke
        End If

        previousWord = inkWord
    Next inkWord
Next lineNode

// 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.
ContextNodeCollection lines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
    InkWordNode previousWord = null;
    foreach (InkWordNode inkWord in
             theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord, lineNode))
    {
        if (previousWord != null &&
            previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
        {
            foreach (Stroke stroke in previousWord.Strokes)
                stroke.DrawingAttributes.Color = Colors.Red;
            foreach (Stroke stroke in inkWord.Strokes)
                stroke.DrawingAttributes.Color = Colors.Red;
        }
        previousWord = inkWord;
