C Sharp programming language Simple English Wikipedia, the free encyclopedia

C# is a versatile programming language that can be used to create a broad variety of applications, including games, apps, websites, and advanced technologies such as AI and machine learning. C#, pronounced “C-sharp,” is an object-oriented programming language from Microsoft that enables developers to build c sharp programming language applications that run on the .NET platform. C# has its roots in the C family of programming languages and shares many of the same characteristics as those found in C and C++, as well as in Java and JavaScript. C# is an object-oriented programming language, which makes development and maintenance easier.

  • Since its introduction, C# has been widely adopted and is the de facto programming language for most Windows-based development.
  • When you start learning a new programming language, it is important to know about the prospect of the language.
  • The curly brackets demarcate the boundaries of a code block.
  • Equality and inequality comparisons for value types compare the actual data values within the instances, unless the corresponding operators are overloaded.

C# is designed to work with Microsoft’s .NET platform, a software ecosystem for developing, compiling and running application code. The platform includes the common language runtime (CLR) and a set of class libraries. C# (pronounced as C sharp) is a general-purpose, object-oriented programming language. It is one of the most popular languages used for developing desktop and web applications. C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg.

Categories of data types

C# language support is provided with the C# Dev Kit extension. It is widely used as a software development methodology to create applications that are more strong and can easily scale. The code is type safe can only access memory locations that it has permission to execute. A unified type system implies that all types, including primitives such as integers, are subclasses of the System.Object class.

  • Both type categories are extensible with user-defined types.
  • It was created to use all capacities of the .NET platform.
  • There are also several built-in snippets included in VS Code that will come up as you type or you can press ⌃Space (Windows, Linux Ctrl+Space) (Trigger Suggest) and we will give you a context specific list of suggestions.
  • A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the unified .NET platform (software framework), all of which support C# and are free, open-source, and cross-platform.
  • It is closer to other popular languages like Java and C++.

In contrast, with procedure-oriented programming languages, managing code becomes difficult as project size grows. Like Java and C++, C# is an object-oriented programming language. It supports the features of object-oriented paradigms such as objects, classes, inheritance, polymorphism, etc. The CLR runs the code and provides services that enable and enhance application development and cross-platform designs. It also offers high-level support for programming languages such as C#, F# and Visual Basic.


This tutorial supplements all explanations with clarifying examples.

Type Safe

C# is the most common programming language used to develop multiple applications in the.NET framework, and it was introduced by Microsoft in 2000. It was designed to be a simple, object-oriented programming language that can be used to create a wide range of applications and software. It features a clear syntax, an object-oriented nature, and platform independence, which makes it simpler for developers to organise their code and makes it more legible and manageable. It is platform-independent in the sense that it may be used to create programmes that operate on different platforms such as Windows, macOS, Linux, and mobile devices. You will also dive into more advanced topics like exception handling, and multithreading. So, whether you are looking to start a career in software development or simply want to expand your programming skills, our C# tutorial is the perfect place to start.

C# Exercises

A type declaration defines the name and members of the new type. Type declarations are based on six of the subcategories available to value and reference types. They include struct types, enum types, tuple value types, class types, interface types and delegate types.


These tutorials are targeted at absolute beginners with no prior knowledge of the C# programming language. When a developer builds a C# application, the source code is compiled into an intermediate language (IL) that conforms to the Common Language Infrastructure standard. The IL code and other application resources are stored in an assembly that is loaded into the CLR when the application runs. The CLR converts the IL code to native machine instructions using a just-in-time compilation process. C# is a versatile programming language primarily used for developing Windows applications, web services, and games within the .NET framework.

In this first instance, they are marking the start and end of the Program class. Both type categories are extensible with user-defined types. Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation.[37] That project was not completed, and the name was later reused. Mojo is still a work in progress, but it’s available to try today via our Mojo SDK. Experience true interoperability with the Python ecosystem. Seamlessly intermix arbitrary libraries like Numpy and Matplotlib and your custom code with Mojo.

Being a high-level language, the basic constructs of C# is easy to understand. It is closer to other popular languages like Java and C++. Hence, it is very easy for someone with experience in these programming languages to switch to C#.

You will see a lightbulb and clicking on it, or pressing ⌘. (Windows, Linux Ctrl+.) provides you with a simple list of fixes/suggestions. Another cool feature is the ability to see the number of references to a method directly above the method. Click on the reference info to see the references in the Peek view. VS Code supports debugging of C# applications running on either .NET or Mono.


This tutorial will teach you basic C# programming and will also take you through various advanced concepts related to C# programming language. The C# language was developed within Microsoft primarily by Anders Hejlsberg, Scott Wiltamuth and Peter Golde. Microsoft released the first widely distributed implementation of C# in July 2000 as part of its .NET framework initiative. C# was intended to be a simple, modern and general-purpose programming language that could be used to develop software components for a distributed environment.

The C# programming language was designed by Anders Hejlsberg from Microsoft in 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO/IEC (ISO/IEC 23270) in 2003. Microsoft introduced C# along with .NET Framework and Visual Studio, both of which were closed-source. Four years later, in 2004, a free and open-source project called Mono began, providing a cross-platform compiler and runtime environment for the C# programming language. A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the unified .NET platform (software framework), all of which support C# and are free, open-source, and cross-platform. C# is a simple & powerful object-oriented programming language developed by Microsoft.
