Namespace: Bio.Util
Assembly: Bio.Core (in Bio.Core.dll) Version: 2.0.0.1 (2.0.0.1)

Syntax

public static HashSet<T> ToHashSet<T>(
	this IEnumerable<T> sequence,
	IEqualityComparer<T> comparer
)

<ExtensionAttribute>
Public Shared Function ToHashSet(Of T) ( 
	sequence As IEnumerable(Of T),
	comparer As IEqualityComparer(Of T)
) As HashSet(Of T)

public:
[ExtensionAttribute]
generic<typename T>
static HashSet<T>^ ToHashSet(
	IEnumerable<T>^ sequence, 
	IEqualityComparer<T>^ comparer
)

[<ExtensionAttribute>]
static member ToHashSet : 
        sequence : IEnumerable<'T> * 
        comparer : IEqualityComparer<'T> -> HashSet<'T>

Parameters

sequence: Type: System.Collections.GenericIEnumerableT
the input sequence
comparer: Type: System.Collections.GenericIEqualityComparerT
The IEqualityComparer used by the HashSet

Type Parameters

T: the type of elements of the sequence

Return Value

Type: HashSetT
a HashSet
