'Catch' を、'Try' ステートメント内にある 'Finally' の後に置くことはできません。 'Catch' を、'Try' ステートメントの外に置くことはできません。 型'<typename>' は、'System.Exception'、または 'System.Exception' を継承するクラスではないため、'Catch' でキャッチでき...
Try 至少必須有一個 'Catch' 或 'Finally' 即時運算視窗中的 'Try' 陳述式無效 'TryCast' 運算元必須為參考型別,但 '<typename>' 是實值型別 'TryCast' 運算元必須是具有類別條件約束的型別參數,但 '<typeparametername>' 沒有類別條件約束 型別'<typename>' 和部分型別 '<typename>' 在容器 '<...
If the Java System.exit(0) call does run across a “catch,” the finally statement will precede the Java “end program” process in its execution. In other words, the system needs to be prompted for the finally block to engage. If the exit is otherwise normal, finally will fail...

A side-note for the use of exit with finally: if you exit somewhere in a try block, the finally won't be executed. Could not sound obvious: for instance in Java you never issue an exit, at least a return in your controller; in PHP instead you could find yourself exiting from a con...
