無法合併 'Widening' 和 'Narrowing' 發行項 2008/08/21 更新:2007 年 11 月Operator 陳述式同時指定 Widening 與Narrowing。在定義轉換運算子時,您必須將它宣告為 Widening 或 Narrowing。因為這兩者具備互斥 (Mutually Exclusive) 的特性,所以您無法同時指定這兩者。

Narrowing the digital divide: in search of a map to mend the gap Although the actual digital divide is widening, the divide between the academic disciplines studying these issues has started to narrow. There is an increasing dialog between scholars in the social sciences and scholars in math, ...
