copy handler
解釋
斷點傳輸復制文件能手-
To avoid a race condition where the last handler can be removed between the null check and the invocation of the event, event sources should also create a copy of the event before performing the null check and raising the event
若要避免爭用條件(最後一個處理程序會在空檢查和事件調用之間被移除) ,在執行空檢查和引發事件之前,事件源還應創建事件的一個副本。
