C# is a multi-paradigm programming language that was developed by Microsoft to be used with its .NET Framework. It was originally named "Cool" but was renamed to C# before release. C# is widely used for applications ranging from simple console programs to complex enterprise systems. Developers use integrated development environments like Visual Studio and SharpDevelop to write and test C# code, which compiles to an executable that runs on the Common Language Runtime.
Introduction to C# Programming
- 1. INTRODUCTION TO C# PROGRAMING ITEC102: Fundamentals of Programming
- 2. Introduction C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. Its development team is led by Anders Hejlsberg. The most recent version is C# 7.3, which was released in 2018 alongsideVisual Studio 2017 version 15.7.2.
- 3. History During the development of the .NET Framework, the class libraries were originally written using a managed code compiler system called Simple Managed C (SMC). In January 1999, Anders Hejlsberg formed a team to build a new language at the time called Cool, which stood for "C-like Object Oriented Language". Microsoft had considered keeping the name "Cool" as the final name of the language, but chose not to do so for trademark reasons. By the time the .NET project was publicly announced at the July 2000 Professional Developers Conference, the language had been renamed C#, and the class libraries and ASP.NET runtime had been ported to C#.
- 4. History The name "C sharp" was inspired by the musical notation where a sharp indicates that the written note should be made a semitone higher in pitch. This is similar to the language name of C++, where "++" indicates that a variable should be incremented by 1 after being evaluated. The sharp symbol also resembles a ligature of four "+" symbols (in a two-by-two grid), further implying that the language is an increment of C++.
- 5. The C# Programming Language C# is a modern object-oriented, general-purpose programming language, created and developed by Microsoft together with the .NET platform. C# is a high-level language that is similar to Java and C++ and, to some extent, languages like Delphi,VB.NET and C.
- 6. The C# Programming Language C# is one of the most popular programming languages. C# language is distributed together with a special environment on which it is executed, called the Common Language Runtime (CLR).
- 7. The Microsoft .NET Framework C# language is not distributed as a standalone product – it is a part of the Microsoft .NET Framework platform (pronounced "Microsoft dot net framework"). .NET Framework generally consists of an environment for the development and execution of programs, written in C# or some other language, compatible with .NET (likeVB.NET, Managed C++, J# or F#).
- 8. The Microsoft .NET Framework It consists of: .NET programming languages (C#,VB.NET and others); an environment for the execution of managed code (CLR), which executes C# programs in a controlled manner;
- 9. The Microsoft .NET Framework It consists of: a set of development tools, such as the csc compiler, which turns C# programs into intermediate code (called MSIL) that the CLR can understand; a set of standard libraries, like ADO.NET, which allow access to databases (such as MS SQL Server or MySQL) and WCF which connects applications through standard communication frameworks and protocols like HTTP, REST, JSON, SOAP andTCP sockets.
- 10. Why C#? a modern programming language widely spread used by millions of programmers around the entire world
- 11. Why C#? very simple and easy to learn suitable for beginners while still widely used in the industry by many large companies one of the most popular programming languages nowadays
- 12. Types of Application The product of the C# compiler is called the “Assembly” It’s either a “.dll” or a “.exe” file. Both run on the Common Language Runtime and are different from native code that may also end with a “.exe” extension.
- 13. C# has two basic types of application Windows Form Application This is GUI based, runs in a window of some sort Console Application This application runs in the command prompt
- 14. Types A. Value 1. Variable name contains the actual value 2. int, double and other primitive types 3. Structure, Enumeration, etc. B. Reference 1. Variable name contains the reference or pointer to the actual value in memory 2. Array, derived from class Array 3. Class, Interface, Delegate, String, etc.
- 15. Where to write/create codes …? Integrated Development Environment (IDE) for the development and testing of software Visual Studio NetBeans Eclipse SharpDevelop
- 16. SharpDevelop 5.1.x #develop #develop (short for SharpDevelop) is a free IDE for C#, VB.NET and Boo projects on Microsoft's .NET platform. It is open-source, and you can download both source code and executables from this site: http://www.icsharpcode.net/OpenSource/SD/Default.aspx
Editor's Notes
- #3: Anders Hejlsberg a prominent Danish software engineer who co-designed several popular and commercially successful programming languages and development tools the original author of Turbo Pascal and the chief architect of Delphi he currently works for Microsoft as the lead architect of C# and core developer on TypeScript.
- #5: Ligature means something that is use to bind
- #6: C# is a modern object-oriented, general-purpose programming language, created and developed by Microsoft together with the .NET platform. There is highly diverse software developed with C# and on the .NET platform: office applications, web applications, websites, desktop applications, mobile applications, games and many others. C# is a high-level language that is similar to Java and C++ and, to some extent, languages like Delphi, VB.NET and C. All C# programs are object-oriented. They consist of a set of definitions in classes that contain methods and the methods contain the program logic – the instructions which the computer executes. You will find out more details on what a class, a method and C# programs
- #7: Nowadays C# is one of the most popular programming languages. It is used by millions of developers worldwide. Because C# is developed by Microsoft as part of their modern platform for development and execution of applications, the .NET Framework, the language is widely spread among Microsoft-oriented companies, organizations and individual developers. For better or for worse, as of this book writing, the C# language and the .NET platform are maintained and managed entirely by Microsoft and are not open to third parties. Because of this, all other large software corporations like IBM, Oracle and SAP base their solutions on the Java platform and use Java as their primary language for developing their own software products. The C# language is distributed together with a special environment on which it is executed, called the Common Language Runtime (CLR). This environment is part of the platform .NET Framework, which includes CLR, a bundle of standard libraries providing basic functionality, compilers, debuggers and other development tools. Thanks to the framework CLR programs are portable and, once written they can function with little or no changes on various hardware platforms and operating systems. C# programs are most commonly run on MS Windows, but the .NET Framework and CLR also support mobile phones and other portable devices based on Windows Mobile, Windows Phone and Windows 8. C# programs can still be run under Linux, FreeBSD, iOS, Android, MacOS X and other operating systems through the free .NET Framework implementation Mono, which, however, is not officially supported by Microsoft.
