Methods

FoldIntoHashCode(int, int)

Folds a hash code for an element into a hash code for a sequence.

Declaration

public static int FoldIntoHashCode(int hashCode, int elementHashCode)

Parameters

Type	Name	Description
int	hashCode	A hash code for a sequence without the element.
int	elementHashCode	A hash code for an element.

Returns

Type	Description
int	A hash code for a sequence that includes the element.

FoldIntoHashCode<T>(int, T)

Folds a hash code for an element into a hash code for a sequence.

Declaration

public static int FoldIntoHashCode<T>(int hashCode, T element)

Parameters

Type	Name	Description
int	hashCode	A hash code for a sequence without the element.
T	element	An element whose hash code is to be folded into the hash code for the sequence.

Returns

Type	Description
int	A hash code for a sequence that includes the element.

Type Parameters

Name	Description
T

HashEnumerable<T>(IEnumerable<T>)

Hashes a sequence of elements.

Declaration

public static int HashEnumerable<T>(IEnumerable<T> sequence)

Parameters

Type	Name	Description
IEnumerable<T>	sequence	The sequence to hash.

Returns

Type	Description
int	A hash code for the entire sequence.

Type Parameters

Name	Description
T	The type of element in the sequence.

HashEnumerable<T>(IEnumerable<T>, IEqualityComparer<T>)

Hashes a sequence of elements.

Declaration

Parameters

Type	Name	Description
IEnumerable<T>	sequence	The sequence to hash.
IEqualityComparer<T>	elementComparer	An equality comparer for elements of the sequence.

Returns
