Generics in DotNet

Question

Generics in Dotnet and its features in system development

Pankajkumar Patel · Answer

Hi Kiran Kumar, Generics in .DotNet is a powerful feature which allows to define classes, interfaces, methods, delegates with a placeholder for the data type. It enables type safety, code reuse, and performance improvements without sacrificing flexibility. Advantages: Type Safety: Errors are caught at compile time instead of runtime. Performance: Avoids boxing/unboxing for value types. Code Reusability: Write one class or method which works with any data type. Generic Types in .NET List : Strongly typed list. Dictionary : Collection of key-value pairs. Queue , Stack , HashSet : Generic collections. Example 1: Generic Class public class GenericBox { public T Value { get; set; } public void Display() { Console.WriteLine($"Value: {Value}"); } } How to use it var intBox = new GenericBox { Value = 10 }; intBox.Display(); // Output: Value: 10 var stringBox = new GenericBox { Value = "Hello" }; stringBox.Display(); // Output: Value: Hello Example 2: Generic Method public class Utility { public static void Swap (ref T a, ref T b) { T temp = a; a = b; b = temp; } } Hope this will help!

Generics in .NET allow you to create classes, methods, and data structures with a placeholder for data types. ?? Features in system development: Type safety (no boxing/unboxing). Code reusability (one class works for any type). Better performance (avoids runtime casting). Flexibility for collections, repositories, and APIs.
