C# Performance: String vs. StringBuilder – The Silent Killer

Has your C# application ever felt slow without an obvious reason? In this video, we dive deep into the world of Memory Management in .NET to uncover a common performance pitfall: the improper use of String vs. StringBuilder. We explore the concept of Immutability, explain why Strings can sometimes be "performance killers," and prove it all with a live benchmark test. What you will learn in this video: - The core difference between Immutable Strings and Mutable StringBuilders. - Why every string modification creates "garbage" in memory. - The common myth: "Is a String just a Char array?" (Spoiler: No!). - Real-world performance comparison using a 10,000-iteration loop. A Note from the Creator: This is my very first technical video! I am treating my "beginner status" as an opportunity to grow and learn alongside this community. I know there is always room for improvement, and I truly value your feedback. Whether it's about the technical content, the visuals, or the delivery—please let me know in the comments how I can improve in the next one. Your support means the world to me as I start this journey.
