InkAnalyzer.FindNodesOfType 方法 (Guid, StrokeCollection)

傳回包含所指定型別之 ContextNode 物件的 ContextNodeCollection，這些物件也就是指定之 StrokeCollection 中的筆劃。

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

語法

'宣告
Public Function FindNodesOfType ( _
    type As Guid, _
    strokes As StrokeCollection _
) As ContextNodeCollection
'用途
Dim instance As InkAnalyzer
Dim type As Guid
Dim strokes As StrokeCollection
Dim returnValue As ContextNodeCollection

returnValue = instance.FindNodesOfType(type, _
    strokes)

public ContextNodeCollection FindNodesOfType(
    Guid type,
    StrokeCollection strokes
)

public:
ContextNodeCollection^ FindNodesOfType(
    Guid type, 
    StrokeCollection^ strokes
)

public ContextNodeCollection FindNodesOfType(
    Guid type,
    StrokeCollection strokes
)

public function FindNodesOfType(
    type : Guid, 
    strokes : StrokeCollection
) : ContextNodeCollection

參數

type
型別：System.Guid

strokes
型別：System.Windows.Ink.StrokeCollection

傳回值

型別：System.Windows.Ink.ContextNodeCollection
用來將筆劃儲存在 strokes collection 中的 ContextNodeCollection，其中包含指定之型別的 ContextNode 物件。

備註

如果節點或節點的其中一個子代參考屬於筆劃集合的筆劃，這個方法會在傳回值中包含該節點。

範例

下列範例會尋找包含 StrokeCollection (selectedStrokes) 中任何筆劃的 LineNode 物件，並且將這些物件標示為紅色。

Dim selectedLines As ContextNodeCollection = theInkAnalyzer.FindNodesOfType(ContextNodeType.Line, selectedStrokes)
Dim line As LineNode
For Each line In  selectedLines
    Dim stroke As Stroke
    For Each stroke In  line.Strokes
        stroke.DrawingAttributes.Color = Colors.Red
    Next stroke
Next line

ContextNodeCollection selectedLines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line,
    selectedStrokes);
foreach (LineNode line in selectedLines)
{
    foreach (Stroke stroke in line.Strokes)
        stroke.DrawingAttributes.Color = Colors.Red;
}
