ICollection<T>.CopyTo(T[], Int32) 方法

定義

從特定的 ICollection<T> 索引開始,將 Array 的項目複製到 ArrayCopies the elements of the ICollection<T> to an Array, starting at a particular Array index.

public:
 void CopyTo(cli::array <T> ^ array, int arrayIndex);
public void CopyTo (T[] array, int arrayIndex);
abstract member CopyTo : 'T[] * int -> unit
Public Sub CopyTo (array As T(), arrayIndex As Integer)

參數

array
T[]

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

arrayIndex
Int32

array 中以零起始的索引,即開始複製的位置。The zero-based index in array at which copying begins.

例外狀況

arraynullarray is null.

arrayIndex 小於 0。arrayIndex is less than 0.

來源 ICollection<T> 中的項目數目,大於 arrayIndex 到目的 array 結尾的可用空間。The number of elements in the source ICollection<T> is greater than the available space from arrayIndex to the end of the destination array.
