Whether it's an airplane's automation or a motorcycle's speedometer, computer programming languages are everywhere around us. And out of all the computer programming languages out there, C# is the most preferred and ideal language to learn. But why? Do not worry. This article contains all the answers to your questions. So, keep reading!

C# is the most widely used programming language for designing software & websites. Most of the software, we use in our daily life are designed using this C# Language. So, let's get started with a detailed Introduction to C#.

Introduction to C#

• C# (pronounced see sharp) is a general-purpose programming language developed by Microsoft in 2000, as part of .NET framework.
• Microsoft Visual Studio is a Programming environment used for writing C#.
• C# was originally designed by Anders Hejlsberg, who currently works as the lead architect of C#.

C# Programming: The Language of God

C#, also known as the Language of God, is a contemporary, broad coding language that can help accomplish hundreds of activities and purposes in different fields. Microsoft designed C# and thus is typically used with the Windows .NET platform. The .NET Framework is actually a computer-developing framework that allows you to create applications for Windows, Azure, Web, and other programming platforms with programming languages including C#, Visual Basic, and F#. C# can also be used in an open standard system. The latest iteration of C# is version 7.2 and is specifically for Standard Language Framework. It has a syntax that is identical to Java. So, if you are familiar with Java or C++, it would be a piece of cake for you. Do not worry if you are a beginner. This article is specifically for beginners so they can have a better understanding before actually studying the language.

History of C#

Unlike well-established languages like Java, Python, PHP, and others, C# is a modern entry to the computer programming community over twenty-one years ago. Microsoft's Anders Hejlsberg, a Denmark computer programmer with a record of renowned innovations, created this programming language in 2000. The programming language was released in 2002 and has benefited all of us till today.

Why Should You Learn C#?

Now, most people have this question: Why Should I Learn C# and Not Others? Well, C# is a one-of-a-kind programming language that's also user-friendly and quicker to comprehend. It has excellent functionality in the areas of efficiency and requires relatively minimal resources. C# may be used to develop a wide range of applications. Some of these are listed below:

• Windows consumer services by utilizing WPF, Windows Forms, and UWP
• Network applications
• Azure and Cloud applications
• Modules, features, and terminal applications
• Internet projects with ASP.NET Core and ASP.NET
• Compatibility, information, and connectivity technologies
• Android and iOS and Android phone applications by utilizing Xamarin

Other than developing applications, it is vital to learn C# because of three main reasons discussed below:

1. High Salaries

In today's world, everyone wants to make a fair living, and computer programmers are among the most fortunate people out there. During the pandemic, almost everyone was having a hard time except the computer programmers because they continued their programming. With other programming languages, you get good salary packages. However, if you know the C# programming language, you will get job opportunities in multinational companies. You can also work online because it is highly demanded nowadays.

2. C#: An Object-oriented Language

The second reason to study C# is that it is an object-intended programming language. Now, you might be thinking: what "object-intended" feature has to do anything with why you should learn C#? Well, object-intended indicates that it organizes data using objects and categories. This programming approach helps to minimize repeated coding and better regulates the data format. And all these factors help beginners to work efficiently and comfortably.

3. Developed By Microsoft 

As discussed earlier, Microsoft created the C# programming language. It is a great reason why you should study C#. It means that there will be a plethora of excellent developer resources available to assist you in learning C# and no scarcity of its resources. And since Microsoft utilizes C# extensively, there is almost no chance that it will become obsolete in the coming years. So, mastering C# is, therefore, a long-term benefit. So, you see, these are solid reasons as to why you must learn C#. Now, we understand that you want to learn even more about C#, and we got you there. The upcoming section is a more in-depth detail of C# so, start taking notes!

Features of C#

Now, let us discuss the main features of the C# programming language in this section which are:

1. Basic Features

• In the C# programming language, pointers are not available.
• It takes the characteristics of automated memory handling and garbage pickup from the .NET framework.
• The "::" and "->" operators are not used in C#.
• Direct memory modification and other risky activities are not permitted.
• "==" is utilized for the comparative procedure, and "=" is for task execution.
• Various ranges of fundamental kinds like Integers, Floats, and so on are available.

2. Modern Features

• C# follows the modern approach and is incredibly strong and convenient for creating interoperability and secure systems.
• Any element conversion into an online service that is accessible via the internet is provided in C#.

3. Type-Safe Features

• Dangerous conversions are not possible in the C# programming language.
• It is possible to check for an overflow of classes, and bound checking can be done.
• The translator immediately initializes numeric forms (objects and instances) to zeros or reference kinds to blank.

4. Object-oriented Features

• Data abstraction, inheritance, flexibility, and interfaces are all supported in C#.
• In Java language, basic kinds (float, int, double) are not things. However, C# has established structures that allow basic kinds to convert into objects.

5. Upgradeable and Scalable Features

• .NET has launched compositions that are self-defining in the areas of declaration. The manifest defines the assembly's identification, iteration, style, and electronic signature, among other characteristics.
• Upgrading software elements is a time-consuming and error-prone process. But, C# supports versioning within the language, which might affect the current programming languages. Sophisticated frameworks can also be established and changed over time.
• We erase old data and replace them with fresh ones to expand our system. Thanks to C#, there is no need to enroll in a flexible linking library.

6. Interoperability Features

• C# comes with built-in functionality for COM as well as Windows programs.
• C# lets clients modify outdated codes by using pointers as harmful code blocks.
• It enables local pointers to be used in a limited sense.
• With C#, Customers no longer need to construct the unidentified or other COM interfaces because these characteristics are already included.
• C# uses elements from Visual Basic for Applications (VB.NET) and other organized code technologies.

C# and C: What is the difference?

When studying the C# programming language, it is crucial to know the difference between C and C#. Both are coding languages, and that is why people often mess up between these two. But, do not worry. We will not let our readers go through the same mistake. Here is the difference: C is an overall-purpose coding language that includes features like recurrence, organized programming, semantic variable access, and many others. It is suitable for use in both system and integrated device programs. C is a limited modeling language whereas, C# is an object-intended programming language that includes features: garbage management, extensibility, type security, and uncomplicated class declarations. It may be used to create smartphones, desktops, and web applications. C# is a high-level programming language with a lot of complexity. So, both programming languages have the same initials but, they are complete opposites of each other.

How C# Programing language works

There is a dedicated set of libraries that are required to run C# in a machine. This collection of libraries is called the .NET framework and it has a collection of libraries that are called CLR’s (common language runtime). The .NET library belongs to Microsoft who has written the library on top of common language infrastructure that is commonly known as CLI which is an internationally acclaimed standard because of the way it assists seamless development and easy usage. When we write code in C#, it takes the form of IL (intermediate language) that is workable according to CLI specifications. These files then take the .dll extension after they are built. An assembly contains multiple dll files.

Basic Commands of C#

The basic commands of C# are quite similar to most popular languages such as C, C++ and Java. Moreover, C# is an object-oriented language so it has similar structures to the languages mentioned above. Some of the basic commands are listed below.

1. Using

The word “Using” is used to include libraries and API’s into your C# code. It is similar to the famous #include statement used in other languages. Any libraries written after the keyword Using will then be downloaded/included at runtime. It is also possible to have multiple Using statements in C#.

2. Class

The keyword class is used to define classes in C#. The syntax is as follows: Class User{ …. }

3. Comments

Comments are a common feature of any programming language. Developers usually add commented code in their files for the understanding of other people or as a reminder to themselves if they ever revisit their own code and want to understand how things work. Commented code is not compiled on run time. The compiler simply ignores any code written after/on a single line or any code written between a /* and a */.

4. Member or Class Variable

Instances are a common occurrence in programming languages. In C# the equivalent term is member or class variable. These are variables that are usually declared and defined when the classes are declared and defined.

5. Identifier

Identifiers are used to declare classes, variables, methods and members in C#. it helps keep track of specific classes and variables that have been defined by the user. Identifiers have simple rules that are to be followed. The rules for C# are similar to the rules for other languages. Also, it is important to note that Identifier can never be a variable name in C#.

Components of C#

Component classes are traditional classes that were used in C and C++ and also made their way to modern C#. These classes are used mainly for the purpose of containment as well as cleanup. Components are present inside a container and can do various operations on the container they belong to. A lot of the business processing is done in these components.

Disadvantages of C#

We have discussed many advantages of the C# programming language in the above sections. Now it is time that you learn about some of the disadvantages of the C#. Please keep in mind that the advantages of C# outweighs its disadvantages. Some of the disadvantages are listed below:

• C# is a substandard x-platform GUI.
• Because C# is a component of the.NET platform, the program must be executed only on a Windows operating system.
• Because it is heavily reliant on the .Net platform, C# is much less versatile.
• C# provides less versatility than C++.
• Error correction demands a high level of expertise and understanding.

Conclusion

We hope that this article helped you in having a better understanding of the C# programming language. C# is an all-in-one programming language, and it has a bright future ahead of it. So, you should definitely give it a go because it is a long-term advantage. We wish you the best of luck on your journey! In the next tutorial, we will design our First Project in C#.
