我很困惑這實際上是如何實現的。當從ClipBoard中獲取數據時發生死鎖（GetDataObject）
在我的應用程序（.NET Framework 4.0中）我有一個 「粘貼」 按鈕。在應用程序啓動時或焦點對象更改時，我會檢查剪貼板中的數據以設置該按鈕的啓用狀態。
現在，它的發生幾次（一臺機器上），這個功能似乎死鎖。看看堆棧跟蹤：

所以，即使我有大量的數據在剪貼板，它應該最終完成。我等了幾分鐘...
現在它再次運作，但我仍然想知道發生了什麼！
* 「當關注對象的變化」 * - 您可以使用[剪貼板事件]（http://stackoverflow.com/q/621577/1997232）來代替。在指責剪貼板之前，您可以創建並向我們展示[mcve]（https://stackoverflow.com/help/mcve）嗎？最好不使用DevExpress（參見[this]（https://www.devexpress.com/Support/Center/Question/Details/T447517））。 – Sinatr
@Sinatr我再也不能自己複製它了。我很幸運地拿到調用堆棧（serveral的時間，有時發生在backgroundworker_completed，有時它發生以後） – toATwork
