I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

05-Nov-2023Using generic collections over non-generic collections in C# offers several benefits:
Type Safety: Generic collections provide type safety, ensuring that you can only add, retrieve, and manipulate items of the specified type. This prevents runtime type errors and enhances code reliability.
Performance: Generic collections are generally more efficient than non-generic collections. They avoid boxing and unboxing operations, which can lead to performance improvements, especially in high-performance scenarios.
Code Clarity: With generic collections, you don't need to cast elements when retrieving them, leading to cleaner and more readable code. Non-generic collections require casting, which can make the code less clear and more error-prone.
Compile-Time Checking: The type parameter in generic collections is checked at compile time, catching type-related issues early in the development process. Non-generic collections rely on runtime checks, which can lead to unexpected errors.
Reusability: Generic collections are highly reusable because they can work with various data types. You can create a single collection class that handles different types, making your code more modular and adaptable.
Reduced Code Redundancy: Using generic collections reduces the need for duplicate collection classes that handle different data types. This leads to more concise code and minimizes redundancy.
Improved Maintainability: Generic collections simplify maintenance because changes or bug fixes in a single collection class can apply to all the data types it handles. Non-generic collections may require updates in multiple places.
Compiler Assistance: When using generic collections, the C# compiler can provide better code completion and assistance, making it easier for developers to work with collections and discover available methods and properties.
Enhanced Development Experience: Generics in C# provide a better development experience in Integrated Development Environments (IDEs) with features like IntelliSense, code analysis, and easier debugging.
Compatibility with LINQ: Generic collections seamlessly integrate with Language-Integrated Query (LINQ), allowing you to write powerful, type-safe queries to manipulate data easily.
In summary, generic collections offer increased type safety, improved performance, cleaner code, and better code maintainability compared to non-generic collections. They are a fundamental part of modern C# programming and are widely used to create robust, flexible, and efficient applications.
