Welcome to C# Generics
Write once, use anywhere—make your C# code smarter, cleaner, and reusable with generics.
Hey there! Have you ever written the same code again and again just for different data types? Ugh, it feels boring, right? I’ve been there too, and trust me, it’s no fun. 😂
That’s where generics step in. They save us from copy-pasting the same stuff. Instead, we write code once and use it with any data type. Pretty cool, isn’t it?
Now, don’t worry if the word generic sounds a bit scary at first. Honestly, it’s simpler than it looks. Think of it like a magic box that works with whatever you put inside. Add an apple, it works. Add a banana, it still works. 🍎🍌 That’s the beauty of generics.
So, in this chapter, we’ll explore how generics work in C#. We’ll go step by step, nice and slow. And of course, I’ll explain things in plain English. No fancy talk. Just you and me learning together.
Here’s what we’ll cover:
-
📖 Introduction to Generics – the “what” and “why.”
-
📦 Generic Classes in C# – creating flexible classes.
-
🛠️ Generic Methods in C# – writing methods once, using them everywhere.
-
📋 Generics List<T> – the super flexible list.
-
🔗 Generics LinkedList<T> – a chain of items, linked together.
-
📒 Generics Dictionary<TKey, TValue> – storing data as key-value pairs.
-
📥 Generic Queue<T> – first in, first out (like a line at the ticket counter).
-
📤 Generic Stack<T> – last in, first out (like stacking plates).
-
🧩 Generics HashSet<T> – unique items, no duplicates allowed.
By the end, you’ll laugh at how easy generics actually are. You’ll wonder why you ever avoided them in the first place. 😉
So grab a cup of coffee ☕, relax, and let’s learn C# generics together.
