HashSet<'T>.SetEquals Method (IEnumerable<'T>)

 

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)

abstract SetEquals : 
        other:IEnumerable<'T> -> bool
override SetEquals : 
        other:IEnumerable<'T> -> bool

Parameters

other
Type: System.Collections.Generic.IEnumerable<'T>

The collection to compare to the current HashSet<'T> object.

Return Value

Type: System.Boolean

true if the HashSet<'T> object is equal to other; otherwise, false.

Exception Condition
ArgumentNullException

other is null.

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.

The following example creates two disparate HashSet<'T> objects and compares them to each another. Initially, the two sets are not equal, which is demonstrated by using the SetEquals method. The allNumbersHashSet<'T> object is then modified, after which the sets are equal.
