try-catch-finally 簡單筆記
程式在執行的時候可能會發生例外的問題。當遇到這些不在意料之中的問題,而在開發程式的時候又沒有對例外 (exception)進行任何的處理,就會導致程式直接停止運行,進而使正在進行的資料處理無法正確完成,例如資料庫的 CRUD 操作,或是將錯誤內容呈現給使用者,這樣會造成不好的用戶體驗。此外如果不幸資料外洩,也會增加遭受有心人士攻擊的風險。
為了避免這些問題的發生,C# 提供了針對例外狀況的處理方式。本文將分享最基本的使用方法。

Learn Java Programming - Exception Handling: Finally Tutorial
This tutorial will build on concepts from my Exception Handling: Try and Catch Tutorial. At the core of exception handling there is one more code block that needs to be addressed, the finally block.
