Заметки

This method deletes only a single Stroke object. To delete a Strokes collection, call the DeleteStrokes method.

This method can result in an error if called while the user is actively laying down ink.

Примеры

This example creates a sample method that uses a foreach loop to iterate through the Stroke objects contained in an Ink object. It then deletes any Stroke object that has more points than maxPointCount.

Private Sub DeleteStrokesByPointCount(ByVal theInk As Ink, ByVal maxPointCount As Integer)
    ' 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 currentStrokes As Strokes = theInk.Strokes
        For Each S As Stroke In currentStrokes
            If S.PacketCount > maxPointCount Then
                theInk.DeleteStroke(S)
            End If
        Next
    End Using
End Sub

private void DeleteStrokesByPointCount(Ink theInk, int maxPointCount)
{
    // 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 currentStrokes = theInk.Strokes)
    {
        foreach (Stroke S in currentStrokes)
        {
            if (S.PacketCount > maxPointCount)
            {
                theInk.DeleteStroke(S);
            }
        }
    }
}
