Introduction
C# collections are powerful tools for managing groups of objects dynamically, ensuring type safety and efficient data manipulation for various applications.
Imagine you're working in the banking industry, tasked with developing a system that manages customer accounts and transactions. You need a way to store customer IDs linked to their account details, ensure no duplicate transaction records, and maintain an ordered list of recent activities. Without the right tools, this task could become cumbersome and error-prone. C# collections like List<T>, HashSet<T>, and Dictionary<TKey, TValue> offer solutions tailored to these challenges. For instance, you can use Dictionary<TKey, TValue> to map customer IDs to account details for quick lookups, HashSet<T> to ensure transaction uniqueness, and List<T> to maintain an ordered sequence of activities. These collections streamline data management, making your application robust and efficient.
