HashSet<T>.SetEquals Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Determines whether a HashSet<T> object and the specified collection contain the same elements.

Namespace:  System.Collections.Generic
Assembly:  System.Core (in System.Core.dll)

Syntax

'Declaration
Public Function SetEquals ( _
    other As IEnumerable(Of T) _
) As Boolean

public bool SetEquals(
    IEnumerable<T> other
)

Parameters

Return Value

Type: System.Boolean
true if the HashSet<T> object is equal to other; otherwise, false.

Implements

ISet<T>.SetEquals(IEnumerable<T>)

Exceptions

Exception Condition
ArgumentNullException

other is nulla null reference (Nothing in Visual Basic).

Remarks

The SetEquals method ignores duplicate entries and the order of elements in the other parameter.

If the collection represented by other is a HashSet<T> collection with the same equality comparer as the current HashSet<T> object, this method is an O(n) operation. Otherwise, this method is an O(n + m) operation, where n is the number of elements in other and m is Count.
