Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

SortedDictionary.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 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

Parameters

array

Array

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

index

Int32

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

Implements

CopyTo(Array, Int32)

Exceptions

ArgumentNullException

array is null.

ArgumentOutOfRangeException

index 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 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.

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 an InvalidCastException, whereas the generic implementations throw an ArgumentException.

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