A HashSet is an unordered collection of the unique elements. It is found in 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 the two HashSets and the function returns the elements of mySet2 which are not in mySet1.
Exception: This method will give ArgumentNullException if the HashSet is null.
Below given are some examples to understand the implementation in a better way:
7 8 9 10
The elements in mySet1 are : Punjab Haryana Jammu Himachal Delhi The elements in mySet2 are : Bangalore Kerala Uttar Pradesh Himachal Delhi The elements in mySet2 are : Bangalore Kerala Uttar Pradesh
