ArrayList.CopyTo Method (Array, Int32)

Copies the entire ArrayList to a compatible one-dimensional Array, starting at the specified index of the target array.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

abstract CopyTo : 
        array:Array * 
        arrayIndex:int -> unit  
override CopyTo : 
        array:Array * 
        arrayIndex:int -> unit

Parameters

array
Type: System.Array

The one-dimensional Array that is the destination of the elements copied from ArrayList. The Array must have zero-based indexing.

arrayIndex
Type: System.Int32

The zero-based index in array at which copying begins.

Implements

ICollection.CopyTo(Array, Int32)

ExceptionCondition
ArgumentNullException

array is a null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

arrayIndex is less than zero.

ArgumentException

array is multidimensional.

-or-

The number of elements in the source ArrayList is greater than the available space from arrayIndex to the end of the destination array.

InvalidCastException

The type of the source ArrayList cannot be cast automatically to the type of the destination array.

The specified array must be of a compatible type.

This method uses Array.Copy to copy the elements.

The elements are copied to the Array in the same order in which the enumerator iterates through the ArrayList.

This method is an O(n) operation, where n is Count.

The following code example shows how to copy an ArrayList into a one-dimensional System.Array.
