我寫程式寫一天有點累，忘記在import其他專案用到還是不小心刪除
總之我寫一天的程式碼就不見了QQ，請問有人有解嗎

最佳解答

Q1: Copy/Paste覆蓋?
Q2: 我的檔案還沒關,代表從一開始就沒有關閉過?(假如沒有關閉Ctrl+Z可以回復的)

假如檔案有關閉過
但是新的專案還沒有編譯運行過
可以去bin資料夾找出先前運行的dll檔案,使用ILSpy反編譯回code(雖然會醜陋了點)

看更多先前的回應...收起先前的回應...

如果是.Net倒是有軟體可以很漂亮地反編譯dll...

...我已經關掉了，我試過網路上的磁碟回復，結果CODE有一部分是亂碼

是什麼QAQ

小魚 iT邦大師 1 級 ‧ 2019-06-02 23:35:38 檢舉

那應該是殺掉檔案的回復吧,
但是你的情況不一樣,
看還有沒有機會反編譯吧...

e6319a5b iT邦新手 4 級 ‧ 2019-06-02 23:38:19 檢舉

我只剩EXE

e6319a5b iT邦新手 4 級 ‧ 2019-06-02 23:40:52 檢舉

既然，我從磁碟回復可以看見有部分亂碼的CODE是不是有方法能復原呢...

暐翰 iT邦大師 1 級 ‧ 2019-06-02 23:44:27 檢舉

EXE也可以反編譯的 e6319a5b

這段code有沒有資安問題,假如沒有可以提供出來讓大家幫你解決

解決方法：
再花一天補回來.
因為你是針對同一個檔案在操作,
基本上是沒有救了,
除非是用編輯器本身的復原功能,
所以寫程式記得要常常做儲存和備份的動作...

e6319a5b iT邦新手 4 級 ‧ 2019-06-02 23:09:35 檢舉

請問這句是指:編輯器本身的復原功能?
我的檔案還沒關

小魚 iT邦大師 1 級 ‧ 2019-06-02 23:28:53 檢舉

Ctrl-Z,
(就是上面的 復原 Ctrl-Z 和 取消復原 Ctrl-Y 兩個按鈕)
只針對開啟的那個檔案,
做回復的動作,
(意思是你要復原其他檔案,
就要切換到那個檔案下,
再按上面的指令,
不過如果檔案的視窗已經關閉應該是無法復原了)
但是編輯器的回復還是有限制的,
我猜可能是跟記憶體大小有關吧...
