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

语法

声明
Public Function FindNodesOfType ( _
    type As Guid _
) As ContextNodeCollection
用法
Dim instance As InkAnalyzer
Dim type As Guid
Dim returnValue As ContextNodeCollection

returnValue = instance.FindNodesOfType(type)

public ContextNodeCollection FindNodesOfType(
    Guid type
)

public:
ContextNodeCollection^ FindNodesOfType(
    Guid type
)

public ContextNodeCollection FindNodesOfType(
    Guid type
)

public function FindNodesOfType(
    type : Guid
) : ContextNodeCollection

参数

type
类型：System.Guid
要查找的 ContextNode 对象的类型。

返回值

类型：Microsoft.Ink.ContextNodeCollection
一个 ContextNodeCollection，其中包含 InkAnalyzer 的节点树中具有指定类型的所有 ContextNode 对象。

示例

下面的示例演示如何遍历 InkAnalyzer (theInkAnalyzer) 中的所有 LineNode 对象。该示例在每行中遍历所有 InkWordNode 对象，如果有两个墨迹单词节点被识别为同一个单词，则将这两个节点标记成红色。

' If two identical ink words occur next to each other, mark them as red.
' Note: This doesn't actually look for pairs that go across two lines.
Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
Dim stroke As Stroke

For Each lineNode In lines

    Dim previousWord As InkWordNode = Nothing
    Dim inkWord As InkWordNode
    For Each inkWord In _
        theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode)

        If Not (previousWord Is Nothing) AndAlso _
                previousWord.GetRecognizedString() = inkWord.GetRecognizedString() Then

            For Each stroke In previousWord.Strokes
                stroke.DrawingAttributes = New DrawingAttributes(Color.Red)
            Next stroke
            For Each stroke In inkWord.Strokes
                stroke.DrawingAttributes = New DrawingAttributes(Color.Red)
            Next stroke
        End If
        previousWord = inkWord
    Next inkWord
Next lineNode

            // If two identical ink words occur next to each other, mark them as red.
            // Note: This doesn't actually look for pairs that go across two lines.
            ContextNodeCollection lines = 
                theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
            foreach (ContextNode lineNode in lines)
            {
                InkWordNode previousWord = null;
                foreach (InkWordNode inkWord in 
                         theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode))
                {
                    if (previousWord != null &&
                        previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
                    {
                        foreach (Stroke stroke in previousWord.Strokes)
                            stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
                        foreach (Stroke stroke in inkWord.Strokes)
                            stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
                    }
                    previousWord = inkWord;
                }
            }
