ContextNodeBaseCollection 類別

包含 ContextNodeBase 物件的集合，這些物件是筆墨分析的結果。

命名空間：  System.Windows.Ink.AnalysisCore
組件：  IACore (在 IACore.dll 中)

範例

下列範例說明如何從 InkAnalyzerBase 對 ContextNodeBaseCollection 執行迴圈。InkAnalyzerBase (theInkAnalyzerBase) 的 FindNodesOfType 方法。這個範例會對所有的行節點執行迴圈，如果同一個單字存在兩個筆墨文字節點，則會將這兩個節點標記為紅色。
