我在.net 3.5（VS c＃express）中創建了這個Windows窗體應用程序。 現在我想轉換它，以便它可以在只安裝.net 2.0的情況下運行。所以在我的項目屬性中：我選擇「目標框架」爲2.0，修正了我得到的錯誤。我的應用程序不會在.net 2.0下運行，在3.5上運行
之後，該應用程序運行正常，安裝.net 3.0，但不會運行在全新安裝的xp與.net 2.0安裝。 「應用程序崩潰，發送錯誤報告」 我該怎麼辦？我想要這個東西在2.0下運行。
這裏是代碼：

感謝
吞嚥異常導致瘋狂。不要捕捉異常並且什麼都不做，你應該讓它傳播到堆棧中。您可以嘗試通過記錄您獲得的異常來縮小發生的情況，包括使其達到程序頂層（在Program.cs中）的異常。 – 2011-02-27 06:03:38
好的，我會試試這個。謝謝 – 2011-02-27 06:11:11
你還沒有包含最重要的信息。源代碼不是問題，因爲你暗示它在.NET 2下編譯。**你的應用程序沒有運行？這個表單是否顯示出來？您看到什麼消息，事件查看器中包含什麼，您嘗試了哪些其他操作系統？ – 2011-02-27 06:48:11
