🔒 Understanding SQL Injection in C# & SQL Server | Complete Practical Lecture

In this lecture, we dive deep into SQL Injection, one of the most dangerous security vulnerabilities in software development. I explain how SQL Injection works, how attackers bypass login forms without knowing the password, and how they can manipulate or destroy database records.

This lecture includes practical demonstrations using C#, SQL Server, and ADO.NET so students can clearly see:

✔ How vulnerable SQL queries are formed
✔ How attackers inject malicious code
✔ How login bypass actually happens
✔ How entire tables can be deleted using SQL Injection
✔ How to protect your applications using parameterized queries
✔ Best practices every developer must follow

Whether you are a beginner or an advanced programmer, this lecture is an essential part of becoming a secure C# developer.
