Type Casting in C# | Implicit, Explicit & Safe Casting Explained
🎯 In this video, we dive deep into Casting in C# — one of the most important concepts in .NET programming. Casting allows you to convert one data type into another, and understanding the types of casting is crucial for avoiding runtime errors and writing efficient code.
🔹 Topics Covered:
✅ Implicit Casting (Type Conversion) → Automatically converts smaller type to larger type.
✅ Explicit Casting (Type Casting) → Requires manual conversion using (type) syntax.
✅ Safe Casting with as keyword → Converts object safely, returns null if incompatible.
✅ Type Checking with is keyword → Checks object type before casting, prevents errors.
✅ Practical C# examples of casting in action.
🔹 Why Learn Casting?
👉 Prevents runtime errors in your applications.
👉 Helps in writing safe and optimized .NET code.
👉 Frequently asked in C# interviews for both beginners and experienced developers.
📌 By the end of this video, you’ll clearly understand when to use implicit, explicit, and safe casting in your C# projects.
