It seeks to demystify object-oriented programming concepts and equip students across various technical disciplines with the practical skills to develop robust applications.
- Fundamentals of C# syntax, variables, and control structures.
- Object-oriented programming principles including classes, inheritance, and polymorphism.
- Utilization of built-in libraries, string methods, and mathematical functions.
- Effective error handling and exception management.
- File I/O operations and database connectivity using ADO.NET.
Excerpt from the Book
1.1 Visual C#.Net
Microsoft’s Visual C# 2015 is one of the most popular general-purpose object-oriented programming languages. It’s powerful, versatile and relatively easy to use. You can use it to develop a wide range of applications that run on the .NET Framework. It comes with a rich repertoire of built-in functions/methods which programmers can use to develop Console, Windows/Forms, Web and Mobile Applications, distributed components, client-server applications, and more. It comes with an advanced code editor, interface designer, integrated debugger and other tools for easy coding and testing.
Using C# has many benefits:
• It is relatively easy to use. Editing, compiling, running and debugging C# programs using the Integrated Development Environment (IDE) is easy.
• It is powerful and versatile.
• It can be used to develop Console, Widows/Forms, Web and Mobile Applications.
• It is object-oriented. Programmers have all the benefits of the object-oriented paradigm such as modularity, inheritance, polymorphism and software reuse.
• It is robust, meaning, it can handle all types of situations - both expected and unexpected. This helps us to minimize errors in programs.
• Modules are linked dynamically (at run-time). Only modules that are needed are linked. This reduces program size, saves memory, and executes faster.
• It uses the Language-Integrated Query (LINQ) to provide built-in query capabilities across a variety of data sources.
• It provides a rich repertoire of built-in/library functions that helps programmers to simplify programming and speed up the software development process.
