當從 Strokes 集合刪除一個或多個 Stroke 物件時發生。

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

語法

'宣告
Public Event StrokesRemoved As StrokesEventHandler
'用途
Dim instance As Strokes
Dim handler As StrokesEventHandler

AddHandler instance.StrokesRemoved, handler

public event StrokesEventHandler StrokesRemoved

public:
 event StrokesEventHandler^ StrokesRemoved {
    void add (StrokesEventHandler^ value);
    void remove (StrokesEventHandler^ value);
}

/** @event */
public void add_StrokesRemoved (StrokesEventHandler value)
/** @event */
public void remove_StrokesRemoved (StrokesEventHandler value)

JScript 不支援事件。

備註

事件處理常式會收到 StrokesEventArgs 型別的引數，其中包含這個事件的相關資料。

在建立 StrokesEventHandler 委派時，您要識別處理事件的方法。若要使事件與您的事件處理常式產生關聯，請將委派的執行個體加入至事件。除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。

範例

在這個範例中，StrokesRemoved 事件處理常式會將已移除的 Stroke 物件儲存至自訂 Strokes 集合。

' Reminder: To avoid a memory leak, you must explicitly call the Dispose() method 
' on any Strokes collection to which an event handler has been attached before 
' the collection goes out of scope. 
Private Sub Strokes_StrokesRemoved(ByVal sender As Object, ByVal e As StrokesEventArgs)
    Try
        ' get the Ink object associated with the 
        ' Strokes collection that fired this event
        Dim mInk As Ink = DirectCast(sender, Strokes).Ink
        ' get the CustomStrokes collection named "REMOVED"
        Dim removed As Strokes = mInk.CustomStrokes("REMOVED")
        ' add the removed Strokes to the custom collection
        removed.Add(mInk.CreateStrokes(e.StrokeIds))

    Catch Ex As ArgumentException
        ' this exception is raised if the named collection ("REMOVED") does not exist
    End Try
End Sub

// Reminder: To avoid a memory leak, you must explicitly call the Dispose() method

// the collection goes out of scope. 
private void Strokes_StrokesRemoved(object sender, StrokesEventArgs e)
{
    try
    {
        // get the Ink object associated with the 
        // Strokes collection that fired this event
        Ink mInk = ((Strokes)sender).Ink;
        // get the CustomStrokes collection named "REMOVED"
        Strokes removed = mInk.CustomStrokes["REMOVED"];
        // add the removed Strokes to the custom collection
        removed.Add(mInk.CreateStrokes(e.StrokeIds));
    }
    catch (ArgumentException)
    {
