What is C sharp (C#)?

Introduction

C sharp (C#) is a simple, modern, general-purpose programming language. It is an object-oriented programming language. C sharp is derived from C++ and Java programming.

C# is use for developing applications for the Microsoft platform. Dutch software engineer Andres Hejlsberg founded and released C# in 2000. It requires the .Net framework to perform a certain task. Csharp works on cross platforms. C sharp aims at developers creating applications using .Net framework. It inherits most of the features of C++ and Visual basics. The program is improving and updating with many attributes. The features like Boolean data variable, memory management, integrated safe type, finding errors, compiling and executing the programs.

Why learn C sharp (C#)?

C# has achieved incredible popularity in the industry. It includes rich sets of instruction statements. This program is useful in creating a variety of applications. C sharp is flexible and supports multiple cross platforms. C# has a large collection of predefined classes. C# provides the availability of the tool which makes it easy to create the graphical user interface. Writing code and designing for the project is easy. Designing the C# from scratch to provide internet and windows applications. The C# program is mostly coded in visual studio which is an IDE. It provides the perfect interface to learn and built projects.

The most interesting part of C sharp is game development. It uses the most popular Unity game engine. Unity is a cross-platform game engine developed by unity technologies. The game engine uses different programming languages. Among them, C# is the most popular one. Today, top games are using unity. C# integrates with Microsoft to target large audience. C# has a large community for new tools that make it even better. The latest features upgraded in C# makes an advance game language.

Key features of C sharp (C#)

• C# provides OOP concepts such as encapsulation, inheritance, polymorphism, and abstraction, making it easier to write modular and maintainable code.
• C# maintains type safety by identifying type-related problems during compilation, reducing runtime errors.
• Garbage Collection: Automatic memory management prevents memory leaks by removing useless objects.
• Cross-Platform Development: C# applications built with.NET Core can run on Windows, macOS, and Linux.
• Asynchronous Programming: The async and await keywords allow for efficient handling of asynchronous operations.
• Extensive Standard Library: Includes built-in functions for collections, file management, threading, networking, and more.
• Interoperability: Enables integration with other programming languages including C++ and JavaScript, as well as interaction with COM objects and unmanaged code.
• Strongly Typed Language: Enforces stringent type checking, which leads to fewer errors and more reliability.
• LINQ (Language Integrated Query): Provides systematic querying of data sources such as databases and collections.
• Secure and Scalable: Offers comprehensive security features, making it suited for enterprise applications.

Syntax and structures of C sharp

A simple C# program uses a structured syntax that includes namespaces, classes, methods, and statements. Here is an example of a simple C sharp program:

Explanation:

• using System; using system; – Includes the System namespace, which contains essential classes and functions.
• namespace HelloWorld; – Defines a namespace to organize code logically.
• class Program – Declares a class named Program.
• static void Main(string[] args) – The entry point of the application.
• Console.WriteLine("Hello, World!"); – Prints “Hello, World!” to the console.

Types of Application Developed with C sharp (C#)

Web applications

A web application is a client-server program that execute in a web browser. C# is useful for building web applications targeting the end-users. Web application uses web forms. Web forms are part of ASP.NET technology. Web forms are be useful for building user interfaces for web applications. C# provides ASP.NET which is a programming framework. ASP.NET lets you create the app that executes on a Web server.

Windows graphical user interface applications

A graphical user interface (GUI) is a type of user interface through which the user interacts with electronic devices. A GUI is designed for desktop use and for a single platform. Windows GUI can be developed using menus, pictures, widgets, etc. GUI can be developed by dragging and dropping the control widgets on the screen. Visual Studio is used for creating windows GUI applications. It allows dragging control items on the screen.

Console-based applications

A console-based application is a computer program which is using via terminal or command line. Console applications usually send a request to the operating system and executed data are displayed on the command line. Console applications are the easiest approach for the beginner to learn software development. It includes the ability to insert data and generate the output at the same time.

Data Types and Variables of C sharp

C# provides various built-in data types:

• Integer types: int, long, short, byte
• Floating-point types: float, double, decimal
• Boolean type: bool
• Character type: char
• String type: string
• Object type: object

Disadvantages of C sharp

• Platform Dependency: Designed primarily for Windows, but.NET Core increases cross-platform interoperability.
• Higher Memory Consumption: Uses more memory than languages such as C or C++.
• Slower Execution Speed: Managed code execution and garbage collection might cause performance overheads.
• Developers have less control over memory management than they do in C++.
• Requires.NET Framework or.NET Core: Applications rely on the.NET ecosystem, which may not be available in all settings.
• Limited support for low-level programming: Not suitable for system level programming or embedded systems.
• Complexity in Large systems: When dealing with extremely large-scale enterprise systems, things can get complicated.
• Learning Curve for Advanced Features: Beginners may struggle with concepts such as delegates, events, and asynchronous programming.
• Dependence on Microsoft Ecosystem: A strong reliance on Microsoft tools and technologies.
