A HashSet is an unordered collection of the unique elements. It comes under System.Collections.Generic namespace. It is used in a situation where we want to prevent duplicates from being inserted in the collection. As far as performance is concerned, it is better in comparison to the list. HashSet
Here, mySet1 and mySet2 are HashSets objects.
Return Type: This method return True if the mySet1 is equal to mySet2 else returns False.
Exception: This method will give ArgumentNullException if the HashSet is null.
Below given are some examples to understand the implementation in a better way:
- C# | Check if a HashSet and a specified collection share common elements
- C# | Remove all elements in a collection from a HashSet
- C# | Check if a HashSet is a superset of the specified collection
- C# | Check if a HashSet is a subset of the specified collection
- C# | Check if a HashSet is a proper superset of the specified collection
- C# | Check if a HashSet is a proper subset of the specified collection
- C# | Create HashSet from another collection
- C# | Check if SortedSet and the specified collection contain the same elements
- C# | Check if SortedSet and a specified collection share common elements
- C# | Copy the elements of collection over a range of elements in ArrayList
- C# | Remove all elements from a HashSet
- C# | Number of elements in HashSet
- C# | Check if a HashSet contains the specified element
- C# | Check if two HashSet<T> objects are equal
- C# | Remove elements from a HashSet with conditions defined by the predicate
