返回作为没有子节点的 ContextNode 对象的所有叶节点。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink.Analysis（在 Microsoft.Ink.Analysis.dll 中）

语法

声明
Public Function FindLeafNodes As ContextNodeCollection
用法
Dim instance As InkAnalyzer
Dim returnValue As ContextNodeCollection

returnValue = instance.FindLeafNodes()

public ContextNodeCollection FindLeafNodes()

public:
ContextNodeCollection^ FindLeafNodes()

public ContextNodeCollection FindLeafNodes()

public function FindLeafNodes() : ContextNodeCollection

返回值

类型：Microsoft.Ink.ContextNodeCollection
一个包含所有叶节点的 ContextNodeCollection。

示例

下面的示例遍历 InkAnalyzer (theInkAnalyzer) 的所有墨迹叶节点，并将其中位于整数 yValue 之下的节点添加到 ArrayList (nodesBelowYValue)。

Dim nodesBelowYValue As New ArrayList()
Dim leafNode As ContextNode
For Each leafNode In theInkAnalyzer.FindLeafNodes()
    ' Add to collection if bottom is lower than yValue
    If leafNode.Location.GetBounds().Bottom > yValue Then
        nodesBelowYValue.Add(leafNode)
    End If
Next leafNode

            ArrayList nodesBelowYValue = new ArrayList();
            foreach (ContextNode leafNode in theInkAnalyzer.FindLeafNodes())
            {
                // Add to collection if bottom is lower than yValue
                if (leafNode.Location.GetBounds().Bottom > yValue)
                {
                    nodesBelowYValue.Add(leafNode);
                }
            }
