C# Set: Key Characteristics Explained

In C#, a set is a type of collection class that has the following characteristics:

1. The elements in the set are unique, meaning that duplicate elements are not allowed in the set.
2. The elements in the set are unordered, meaning there is no fixed order for the elements in the set.
3. Collections are mutable, meaning elements can be added or removed from the collection.
4. Sets have dynamic sizes, meaning they can adjust in size as needed.
5. Sets offer efficient search operations, allowing for quick checks to see if a certain element is present in the set.
6. Sets are commonly used to store unique elements and provide convenient operations such as union, intersection, and difference.
