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.

The most common use of the finally block is to close file handles that may have been opened in the try statement.
