C# Programming Language
Introduction :
The C# programming language is one of the object-oriented programming languages (OOP).
Developed by Microsoft and running on the .Net Framework, this language is designed to facilitate the development of web and application software.
This language has become one of the most popular programming languages due to its simplicity and power.
Summary :
C# with its modern features, easy learning, user-friendliness, and its power has become one of the most popular languages for years and is used in the design of various software, from games to business programs.
Body :
C# uses features such as static typing, memory management, data types, database management and extensive libraries.
This language allows developers to write clean and maintainable code using object-oriented principles and design patterns.
Also, the .Net Framework ecosystem helps facilitate the development process, integrated development environment (IDE) such as Visual Studio provides advanced features and tools for developers.
C# also supports synchronous programming.
Due to its many uses, this language is the right choice for large and small projects.
(Example - C# Code):
History :
The C# language was developed under the direction of Anders Heilsberg at Microsoft and its purpose is to create a modern and efficient language for the .Net Framework, the first version of C# was released in 2000.
(Anders Heilsberg)
Over time, with the addition of new features and performance improvements, C# has been updated and various versions of it have been presented.
In 2010, version 4 was presented with new features such as Dynamic and Parallel Task. In 2014, Microsoft decided to open source it, which increased the participation of the programming community in its development.
Now, C# has become a popular language worldwide, which is used in various fields such as game development (Unity and recently Unreal Engine), Web Development (ASP.NET)
Android application development (Xamarin) and in 2022 (MAUI) technology was introduced, this technology is actually cross-platform.
Cross-platform refers to those programs or software that can run on multiple computer platforms.
C# in Different Fields :
*Mobile programming :
Xamarin is a framework of C# language and similar to Flutter and React Native is used to develop cross-platform applications.
- It means that you only need to write the program once and output it for different devices, and you don't need to rewrite the written program for each platform. Using this framework, you can program for both Android and iOS devices. Of course, remember that in order to be able to write and output programs for iOS devices, you must use a device with MacOS operating system installed on it.
*Development of Web Pages :
To code the server side of websites using C#, you can use the popular ASP.Net technology.
ASP stands for Active Server Page. To work with this framework, you must first learn the C# language well, because many of the codes used in ASP.Net are in the C# language.
Also, the database used is Microsoft SQL Server and the web service required to run pages written with ASP is IIS.
The difficult learning curve and higher costs of programming the server side of a website using ASP.Net are disadvantages of this technology.
*Windows application development :
One of the best options for developing desktop applications is using C#. Using Visual Studio, you can use Windows Forms App to develop GUI applications for the desktop.
(Example - Windows Forms App) :
Of course, from the technology (WPF) stands for Windows Presentation Foundation.
can also be used to develop programs with a graphical interface and offer you newer and more special features; For example, using WPF you can create applications with a more flexible and robust UI, whereas Windows Forms is not and is simpler. In terms of security and speed, WPF performs better than Windows forms.
(Example – WPF) :
Apart from these two cases, you can use Console Applications to write programs that run in the console environment and do not have any graphical components.
(Example - Console App):
You can also design client applications for Windows 10 and 11 using UWP (Universal Windows Platform).
(UWP-Example):
*Artificial intelligence:
One of the most used branches of artificial intelligence is machine. Computers machines without programs with clear instructions, learn from living things using examples and experiences.
Machine learning, or ML, which stands for machine learning, is used in a variety of fields, such as search engines, filtering incoming emails, face recognition, medical diagnosis, and language. By using C# and ML.Net software, you can program with C# language and in the field of machine.
This package is written in C# and C++ and was introduced by Microsoft in 2018. Microsoft has even used this library in its products such as Windows, Office software package and Bing search engine.
Currently, only 64-bit systems can use ML.Net and must have .Net Core 3.0 installed on your system to be able to use it. The features of ML.Net include: being cross-platform, the ability to connect C#
to the famous Tensorflow library, using any type of relational database management system (RDBMS such as Oracle, SQLite, PostgreSQL), modeling and automatic machine learning and network training. Deep Neural with GPU.
*IOT :
Using C# and libraries required for IOT or Internet of Things, you can develop IOT-based applications.
The two packages that should be used for IOT development with C# are:
*System.Device.Gpio.
*Iot.Device.Bindings.
C# is an ideal language for developing IOT-based projects that use multiple sensors. Since C# can directly use RAM memory, does not require much processing power and has a simple syntax, it can be used in the Internet of Things.
*Electronics:
C# is also widely used in the field of electronics due to having libraries and classes for working with various hardware ports as well as working with various microcontrollers including Arduino and Raspberry Pi. Even in the field of robotics and programming, you can use C# for them.
(Example – C# App and Arduino):
Advantages and disadvantages of C# language :
*Benefits:
1.The syntax is similar to Java, C++ and C language.
2.The most powerful programming language that uses the .Net Framework.
3.High security.
4.Ability to reuse codes.
5.It has rich libraries for use in different fields.
6.Being multi-platform (Cross-Platform).
*Disadvantages:
1.Poor communication with the API.
2.Inability to use assembly language directly.
3.High dependency on .Net framework.
4.Difficult learning curve.
Conclusion :
C# language is one of the main languages in software development. This language with its strong and modern capabilities can meet the needs of different programmers.
There is a bright future for C# and it is expected to continue to grow and develop with new developments.
