AnalysisAlternateBase.AlternateNodes 属性

获取与此备选项关联的 ContextNodeBase 对象。

命名空间：  System.Windows.Ink.AnalysisCore
程序集：  IACore（在 IACore.dll 中）

语法

声明
Public ReadOnly Property AlternateNodes As ContextNodeBaseCollection
用法
Dim instance As AnalysisAlternateBase
Dim value As ContextNodeBaseCollection

value = instance.AlternateNodes

public ContextNodeBaseCollection AlternateNodes { get; }

public:
property ContextNodeBaseCollection^ AlternateNodes {
    ContextNodeBaseCollection^ get ();
}

/** @property */
public ContextNodeBaseCollection get_AlternateNodes()

public function get AlternateNodes () : ContextNodeBaseCollection

属性值

类型：System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
与此备选项关联的 ContextNodeBase 对象。

备注

因为这些 ContextNodeBase 对象对应于备选项，所以除非这些对象是最佳备选项（也就是 AnalysisAlternateBaseCollection 中的第一个元素），否则它们不是 InkAnalyzerBase 的 RootNode 的后代。

示例

此示例确定 AnalysisAlternateBase (selectedAlternate) 是否与 AnalysisAlternateBaseCollection (currentAlternates) 中的最佳备选项具有相同的分段。分段是指笔画划分为 ContextNodeBase 对象的方式。

Dim hasSameSegmentationAsTop As Boolean = True
