將 Stroke 物件從 Ink 物件中刪除。

命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Sub DeleteStroke ( _
    stroke As Stroke _
)
'用途
Dim instance As Ink
Dim stroke As Stroke

instance.DeleteStroke(stroke)

public void DeleteStroke(
    Stroke stroke
)

public:
void DeleteStroke(
    Stroke^ stroke
)

public void DeleteStroke(
    Stroke stroke
)

public function DeleteStroke(
    stroke : Stroke
)

參數

stroke
型別：Microsoft.Ink.Stroke
要刪除的 Stroke 物件。

備註

這個方法只會刪除單一 Stroke 物件。若要刪除 Strokes 集合，請呼叫 DeleteStrokes 方法。

如果在使用者正停留在筆墨上時呼叫這個方法，可能會造成錯誤。

範例

這個範例所建立的範例方法，會使用 foreach 迴圈逐一查看 Ink 物件中包含的 Stroke 物件。接著會在 Stroke 物件的點數比 maxPointCount 多時，刪除物件。

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);
            }
        }
    }
}
