Collection<T>.ICollection.CopyTo(Array, Int32) Method

Definition

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

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

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

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

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

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

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

array is null.

index is less than zero.

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 index 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.

Note

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

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