定义

从特定的 ICollection<T> 索引开始,将 Array 的元素复制到一个 Array 中。Copies the elements of the ICollection<T> to an Array, starting at a particular Array index.

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

参数

T[]

一维 Array,它是从 ICollection<T> 复制的元素的目标。The one-dimensional Array that is the destination of the elements copied from ICollection<T>. Array 必须具有从零开始的索引。The Array must have zero-based indexing.

arrayIndex
Int32 Int32 Int32 Int32

array 中从零开始的索引,从此处开始复制。The zero-based index in array at which copying begins.
