好了做一個BalloonToolTip，所以我試圖做一個簡單的截圖程序，我需要的程序顯示一個BalloonToolTip時的截圖拍攝並在程序設置爲運行在啓動。下面的代碼顯示了我的整個程序，沒有形式，也沒有設計師。只是一個從Program.cs運行的程序，它不是控制檯應用程序。C＃如何從非形式應用

現在，你可能並不需要所有這一切，但我要確保我沒惹什麼都漲的過程中，並且是被發現我的資源和圖標設置，我只是不理解爲什麼這不起作用。
是否採取截圖？當你調試應用程序時，你可以在'BalloonTip'方法中找到一個斷點嗎？不知道你是否有複製/粘貼問題 - 但我不確定你是否允許嵌套方法（'HotKeyManagerPressed'在'CreateNotifyIcon'內）？ –
