屬性值

型別：System.Windows.Ink.ContextNodeCollection
與這個替代項目相關聯的 ContextNode 物件。

備註

因為 ContextNode 物件對應於替代項目，所以除非這些物件是頂端替代項目，也就是 AnalysisAlternateCollection 中的第一個項目，否則這些物件就不是 InkAnalyzer 之 RootNode 的子代。

AlternateNodes 一定會傳回分葉節點的集合。例如，AnalysisAlternate() 為 LineNode，則 AlternateNodes 會傳回 InkWordNode 物件的集合，而不是 LineNode 物件的集合。

範例

這個範例會檢查 AnalysisAlternate (selectedAlternate) 是否與 AnalysisAlternateCollection (currentAlternates) 中的頂端替代項目具有相同的分割。分割是指筆劃分為 ContextNode 物件的方式。

Dim hasSameSegmentationAsTop As Boolean = True
If currentAlternates.Count > 0 Then
    Dim topAlternate As AnalysisAlternate = currentAlternates(0)
    ' First check if selected alternate is the top alternate
    If selectedAlternate = topAlternate Then
        hasSameSegmentationAsTop = True
    Else
        ' Check to see if they have the same strokes
        If topAlternate.AlternateNodes.Count <> selectedAlternate.AlternateNodes.Count Then
            hasSameSegmentationAsTop = False
        Else
            ' Check that each node matches the alternates
            Dim i As Integer
            For i = 0 To topAlternate.AlternateNodes.Count - 1
                If topAlternate.AlternateNodes(i).Strokes.Count <> _
                   selectedAlternate.AlternateNodes(i).Strokes.Count Then

                    hasSameSegmentationAsTop = False
                    Exit For
                End If

                Dim stroke As Stroke
                For Each stroke In topAlternate.AlternateNodes(i).Strokes
                    If Not selectedAlternate.AlternateNodes(i).Strokes.Contains(stroke) Then

                        Exit For

    End If
End If

bool hasSameSegmentationAsTop = true;
if (currentAlternates.Count > 0)
{
    AnalysisAlternate topAlternate = currentAlternates[0];

            for (int i = 0;
                (i < topAlternate.AlternateNodes.Count) && hasSameSegmentationAsTop; i++)
            {
                if (topAlternate.AlternateNodes[i].Strokes.Count !=
                      selectedAlternate.AlternateNodes[i].Strokes.Count)
                {
                    hasSameSegmentationAsTop = false;
                    break;
                }

                foreach (Stroke stroke in topAlternate.AlternateNodes[i].Strokes)
                {

                    {
                        hasSameSegmentationAsTop = false;
