Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Copies the elements of a HashSet<T> collection to an array.

Overloads

CopyTo(T[])	Copies the elements of a HashSet<T> object to an array.
CopyTo(T[], Int32)	Copies the elements of a HashSet<T> object to an array, starting at the specified array index.
CopyTo(T[], Int32, Int32)	Copies the specified number of elements of a HashSet<T> object to an array, starting at the specified array index.

CopyTo(T[])

Source:

HashSet.cs

Copies the elements of a HashSet<T> object to an array.

public:
 void CopyTo(cli::array <T> ^ array);

public void CopyTo (T[] array);

member this.CopyTo : 'T[] -> unit

Public Sub CopyTo (array As T())

Parameters

array

T[]

The one-dimensional array that is the destination of the elements copied from the HashSet<T> object. The array must have zero-based indexing.

Exceptions

ArgumentNullException

array is null.

Remarks

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

CopyTo(T[], Int32)

Source:

HashSet.cs

Copies the elements of a HashSet<T> object to an array, starting at the specified array index.

public:
 virtual void CopyTo(cli::array <T> ^ array, int arrayIndex);

public void CopyTo (T[] array, int arrayIndex);

abstract member CopyTo : 'T[] * int -> unit
override this.CopyTo : 'T[] * int -> unit

Public Sub CopyTo (array As T(), arrayIndex As Integer)

Parameters

array

T[]

The one-dimensional array that is the destination of the elements copied from the HashSet<T> object. The array must have zero-based indexing.

arrayIndex

Int32

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

Implements

CopyTo(T[], Int32)

Exceptions

ArgumentNullException

array is null.

ArgumentOutOfRangeException

arrayIndex is less than 0.

ArgumentException

arrayIndex is greater than the length of the destination array.

Remarks

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

CopyTo(T[], Int32, Int32)

Source:

HashSet.cs

Copies the specified number of elements of a HashSet<T> object to an array, starting at the specified array index.

public:
 void CopyTo(cli::array <T> ^ array, int arrayIndex, int count);

public void CopyTo (T[] array, int arrayIndex, int count);

member this.CopyTo : 'T[] * int * int -> unit

Public Sub CopyTo (array As T(), arrayIndex As Integer, count As Integer)

Parameters

array

T[]

The one-dimensional array that is the destination of the elements copied from the HashSet<T> object. The array must have zero-based indexing.

arrayIndex

Int32

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

count

Int32

The number of elements to copy to array.

Exceptions

ArgumentNullException

array is null.

ArgumentOutOfRangeException

arrayIndex is less than 0.

-or-

count is less than 0.

ArgumentException

arrayIndex is greater than the length of the destination array.

-or-

count is greater than the available space from the index to the end of the destination array.

Remarks

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