參數

array
Array

一維 Array,是從 ArrayList 複製過來之項目的目的端。The one-dimensional Array that is the destination of the elements copied from ArrayList. Array 必須有以零為起始的索引。The Array must have zero-based indexing.

例外狀況

arraynullarray is null.

array 是多維的。array is multidimensional.

-或--or- 來源 ArrayList 中的項目數大於目的 array 可包含的項目數。The number of elements in the source ArrayList is greater than the number of elements that the destination array can contain.

來源 ArrayList 的類型無法自動轉換成目的 array 的類型。The type of the source ArrayList cannot be cast automatically to the type of the destination array.

備註

指定的陣列必須是相容的類型。The specified array must be of a compatible type.

這個方法會使用 Array.Copy 來複製元素。This method uses Array.Copy to copy the elements.

元素會以列舉值逐一查看 ArrayList的相同順序複製到 ArrayThe elements are copied to the Array in the same order in which the enumerator iterates through the ArrayList.

這個方法是 O(n) 作業,其中 ncountThis method is an O(n) operation, where n is count.
