CollectionBase.ICollection.CopyTo(Array, Int32) CollectionBase.ICollection.CopyTo(Array, Int32) Method


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

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


Array Array

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

Int32 Int32

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



array is multidimensional.


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

The type of the source CollectionBase 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.

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