HashSet<T>::SetEquals Method (IEnumerable<T>^)
Determines whether a HashSet<T> object and the specified collection contain the same elements.
Assembly: System.Core (in System.Core.dll)
Parameters
- other
-
Type:
System.Collections.Generic::IEnumerable<T>^
The collection to compare to the current HashSet<T> object.
Return Value
Type: System::Booleantrue if the HashSet<T> object is equal to other; otherwise, false.

ISet<T>::SetEquals(IEnumerable<T>^)| 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.
