[問題] 泛型的約束條件？
public static TItem 相加<TItem>(TItem 左值, TItem 右值)
where TItem: 這裡該填什麼？
{
return 左值 + 右值;
}
希望TItem 「可以運算」
例如：int float double 之類的型別
請問要怎麼限制泛型條件？
已經試過
where TItem:int
where TItem:System.Int32
可是都不行......
如果不行用泛型去解
那勢必得用多載的方式去寫
那又得寫一堆類似的程式碼了.......
寫個程式整天都在面對一堆小改的程式碼
讓我想把word的合併列印拿出來用了........
