Copies the elements of the ICollection to an Array, starting at a particular Array index.

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

private abstract CopyTo : 
        array:Array * 
        arrayIndex:int -> unit  
private 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 ICollection. 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

-or-

array does not have zero-based indexing.

-or-

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

-or-

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