Collection in C#

Collections in C# provide a flexible way to store, manage, and manipulate groups of objects They include types like lists, dictionaries, queues, stacks, and sets, available in the System.Collections and System.Collections.Generic namespaces . Generic collections like List<T> and Dictionary<TKey, TValue> offer type safety and better performance compared to non-generic ones. Collections support operations like adding, removing, searching, and iterating through elements efficiently. They are widely used for handling dynamic data in applications of all sizes. Mastering collections is essential for building organized, scalable, and high-performance C# programs.
