Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

List.cs

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

 virtual void System.Collections.ICollection.CopyTo(Array ^ array, int arrayIndex) = System::Collections::ICollection::CopyTo;

void ICollection.CopyTo (Array array, int arrayIndex);

abstract member System.Collections.ICollection.CopyTo : Array * int -> unit
override this.System.Collections.ICollection.CopyTo : Array * int -> unit

Sub CopyTo (array As Array, arrayIndex As Integer) Implements ICollection.CopyTo

Parameters

array

Array

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

arrayIndex

Int32

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

Implements

CopyTo(Array, Int32)

Exceptions

ArgumentNullException

array is null.

ArgumentOutOfRangeException

arrayIndex is less than 0.

ArgumentException

array is multidimensional.

-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.

Remarks

Note

If the type of the source ICollection cannot be cast automatically to the type of the destination array, the nongeneric implementations of ICollection.CopyTo throw InvalidCastException, whereas the generic implementations throw ArgumentException.

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