What is the purpose of the “distinct” in C#?

In C#, the Distinct method is used to remove duplicate elements from a sequence and return a new sequence containing unique elements. It uses the default equality comparer to compare elements, but a custom comparer can also be used to specify how to determine if elements are equal. The Distinct method is often used in conjunction with LINQ queries and can be used to retrieve unique elements from a collection or array.
