屬性值

型別：System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
與這個替代項目相關聯的 ContextNodeBase 物件。

備註

因為這些 ContextNodeBase 物件會對應至替代項目，所以除非它們是最佳替代項目 (即 AnalysisAlternateBaseCollection 內的第一個項目)，否則不會是 InkAnalyzerBase 之 RootNode 的子代 (Descendant)。

範例

這個範例會判斷 AnalysisAlternateBase (selectedAlternate) 是否具有與 AnalysisAlternateBaseCollection (currentAlternates) 中的頂端替代項目相同的分割。分割表示筆劃分為 ContextNodeBase 物件的方式。
