About this course

Building robust software in C# requires a solid grasp of object-oriented principles, efficient data handling, and reliable database integration. This text-only course guides you from the fundamental concepts of C# classes and one-dimensional arrays to establishing secure, functional database connections using ADO.NET. You will learn to structure your code cleanly, manage collections of data, and read or write database records. What you'll learn: - Understand core object-oriented programming (OOP) concepts in C#, including classes, objects, and properties. - Manipulate one-dimensional arrays using traditional loops and modern LINQ queries. - Configure database connections using ADO.NET to interact with relational databases. - Execute SQL commands from C# code to read, insert, and update database records safely. - Apply clean coding practices to separate business logic from data access layers. You will start with the essential terminology of OOP and array structures before progressing to practical database connection configurations. Through detailed code walkthroughs and written exercises, you will learn how to bind these concepts together into cohesive applications. This course is designed for beginners with a basic understanding of C# syntax who want to learn OOP, array manipulation, and database connectivity. No advanced prerequisites are required. Start reading today to build your foundation in C# OOP and database programming.
