C# (programming language) Courses

C# (pronounced see-sharp) is a general-purpose, object-oriented programming language. It was designed as a multi-paradigm programming language by Microsoft in around 2000 as part of its .NET initiative. The .NET framework and .NET applications are multi-platform applications that you can use with programming languages such as C++, C#, Visual Basic, and COBOL. C# is open-source and was designed to be simple yet modern, flexible yet powerful and versatile yet easy to learn and program with. Many programming languages in the past were designed for specific purposes. C# was developed with business and enterprise needs in mind. By providing functionality to support modern-day software development such as web applications, mobile, and response app needs, C# supports many features of modern-day programming languages. That includes generics, var types, dynamic programming, asynchronous programming, pattern matching, advanced debugging, and exception handling, to name a few.

Thanks to the .NET framework, C# has many advantages over C++. C# is a refined and modernized version of C++. C++ was developed to bring object-orientation to C, an older but widely used language, and C++ became the de-facto language for building applications for Windows as well as infrastructure and low-level applications. Visual Basic was for business applications. What C# does is combine the rapid development capabilities of VB with the power of C++. C# also has many new data types, type-safety, to ensure you do not unknowingly reuse initialized variables. It uses a simplified syntax, a huge improvement over the complex coding often required in C++. C# also removes memory management issues thanks to .NET’s garbage collection scheme. You do not have to reference items for garbage collection; the system can reclaim that memory as required. Finally, you can use C# to interoperate with other languages on the .NET platform, a huge benefit in terms of system interoperability.

Encapsulation can be used in C# to hide data and program behavior from users. With encapsulation, you can group properties, methods, and other members so that they are treated as a single object. It is a means to prevent the user of a given class from manipulating program objects in ways that were not intended by the designer or developer. Encapsulation hides how a program operates without affecting how it works while still allowing users to service requests for functionality and add or modify internal data or methods to meet changing needs. For example, suppose you have an object called “Patient” that contains patient-related data. In that case, you can use encapsulation to provision patient-specific data to those who need it without exposing all patient data. In addition to information hiding, you can use encapsulation in C# to improve your code's reusability, and it also makes it easier to perform unit testing.
