UtilityLibrary.Core

AddRange

Adds a range of elements to the end of the HashSet.

using UtilityLibrary.Core;
using System.Collections.Generic;

HashSet<int> numbers = new HashSet<int> { 1, 2, 3 };
IEnumerable<int> additionalNumbers = new List<int> { 4, 5, 6 };

numbers.AddRange(additionalNumbers);

// Result: numbers = { 1, 2, 3, 4, 5, 6 }

In this example, the AddRange method is used to add the elements from the additionalNumbers collection to the existing HashSet<int>. After calling the method, the numbers HashSet contains all the elements from both the original HashSet and the additional collection.
