Examples
In this example, the Contains method is used to determine if a particular Stroke object is a member of the Strokes collection. If so, the color of the Stroke is set to red.
' Access to the Strokes property returns a copy of the Strokes object.
' This copy must be implicitly (via using statement) or explicitly
' disposed of in order to avoid a memory leak.
Using allStrokes As Strokes = mInkOverlay.Ink.Strokes
If allStrokes.Contains(specialStroke) Then
specialStroke.DrawingAttributes.Color = Color.Red
End If
End Using
// Access to the Strokes property returns a copy of the Strokes object.
// This copy must be implicitly (via using statement) or explicitly
// disposed of in order to avoid a memory leak.
using (Strokes allStrokes = mInkOverlay.Ink.Strokes)
{
if (allStrokes.Contains(specialStroke))
{
specialStroke.DrawingAttributes.Color = Color.Red;
}
}
