示例
下面的示例演示如何从 InkAnalyzer (theInkAnalyzer) 的 InkAnalyzer.FindNodesOfType(ContextNodeType, ContextNode) 方法遍历 ContextNodeCollection。该示例遍历所有行节点，如果两个墨迹单词节点出现在同一个单词中，则将这些节点标记成红色。
' 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(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
Dim stroke As Stroke
For Each lineNode In lines
Dim previousWord As InkWordNode = Nothing
Dim inkWord As InkWordNode
For Each inkWord In _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode)
If Not (previousWord Is Nothing) AndAlso _
previousWord.GetRecognizedString() = inkWord.GetRecognizedString() Then
For Each stroke In previousWord.Strokes
stroke.DrawingAttributes = New DrawingAttributes(Color.Red)
Next stroke
For Each stroke In inkWord.Strokes
stroke.DrawingAttributes = New DrawingAttributes(Color.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(Microsoft.Ink.ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
InkWordNode previousWord = null;
foreach (InkWordNode inkWord in
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode))
{
if (previousWord != null &&
previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
{
foreach (Stroke stroke in previousWord.Strokes)
stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
foreach (Stroke stroke in inkWord.Strokes)
stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
}
previousWord = inkWord;
}
}
