  • This is an integral part of the .net framework, making it more popular among .net professionals.

Prerequisites for Learning C#

For learning C sharp programming for beginners, it’s essential to have basic computer knowledge, basic knowledge of the Object-Oriented programming approaches, and basic knowledge of C programming language concepts to understand C# basics easily.

Tip: You can grab an opportunity to become a potential .Net Expert by enrolling in Microsoft .Net Online Training & Certification Courses.

Getting Ready

Before learning your first C# application, you’ll require an editor or an Integrated Development Environment (IDE), where you can type and compile your code. Visual Studio, developed by Microsoft, is the best IDE out there for C# developers. The current version of Visual Studio is Visual Studio 2022, version 17.3.

Visual Studio 2022 Editions include- Visual Studio Enterprise, Visual Studio Professional, and Visual Studio Community. 

The visual Studio Community edition is free; we’ll use it. Alternatively, you may also use Visual Studio Code. Visual Studio Code is a free, lightweight, open-source code editor for writing and debugging code. VS Code supports major programming languages.

You may download Visual Studio 2017 Community here.

Learn C# - Framework vs. Programming Language vs. IDE

Before starting with C# programming, it is necessary to understand the difference between three popular terms – Framework, Programming Language, and IDE. In most cases, all of these terms are used interchangeably by beginners without knowing their actual meaning and significance. Where -

Visual Studio is an IDE, .NET is a framework, and C# is a programming language.Learn C# Programming Tutorial for Beginners

The Microsoft .NET framework has a huge collection of class libraries and reusable components. Further, you need a software application to invoke those components. The software application will be written in programming languages like C sharp or VB .NET etc.

Tip: Read What are the Roles & Responsibilities of a .Net Developer to learn about the role and significant responsibilities of Dot Net developers.

If you are interested in writing any professional application that is really huge in size. Here, you need to automate certain things to speed up the task. The IDE offers these code management and automation techniques. It may be challenging to work with all the utilities initially, but things will get smoother as soon as you become more familiar with them.

Learn C# Programming Structure

Before we switch to advanced concepts of C# for beginners, let’s first study its programming structure. A C# program consists of different parts such as– Namespace, comments, class, class methods, statements, expressions, one main method, etc.

Let us look at the simple program that prints “Hello JanBask” as the final output-

[code lang="php"] using System; namespace HelloJanBaskApplication { class HelloJanBask { static void Main(string[] args) { /* my first program in C# */ Console.WriteLine(“Hello JanBask”); Console.ReadKey(); } } }[/code]

Output – Hello JanBask

Let’s discuss each and every concept of the program in detail –

  • The “using” keyword in the first line is written to include the “System” namespace in the program. The “using” keyword can be utilized in a single program more than once.
  • In the second line, “namespace” is used as the declaration. Inside the namespace, we can declare multiple classes together. For the above example, the declared class name is – “HelloJanBask.”
  • In the third line, “class” is used as the declaration. Inside “class,” we can declare multiple methods together. For the above example, there is one “Main” method, and “WriteLine” and “Readkey” are the sub-methods.
  • The “Main” method is an entry point for C sharp programs. This method explains the class's behavior and decides when it needs to be executed.
  • The comment section /**\ is used to increase the overall readability of the program. This is a good programming practice and necessary for all C sharp developers.
  • The “WriteLine” method is used to display the message on the screen, and the “Readkey” method in the last line controls the behavior of previously used methods.

You are ready to write a short program in C# from the above discussion. Make sure that you are familiar with the syntax well, and it should be used wisely without making multiple errors. Also, it is case-sensitive, so C sharp program should be written carefully.

How to compile or execute a C# program using IDE and Command Prompt?

Visual Studio .NET Framework

  • Open the Visual Studio from Program Files.
  • In the Menu bar, there is one File Option. You need to choose the “New” option, then click on the sub-option “Project.”
  • Select the “Windows” option on the left side and choose Console Application on the right hand.
  • Give a good name to your project and press the “OK” button to save the project in Solution Explorer.
  • Now, you are ready to start coding in the code editor.
  • There is a Run option at the top, or you can use the F5 key to execute the C# program. A command prompt will appear in front of you with the final output.

Command-line prompt for program execution

If you are not interested in Visual Studio IDE, there is another option, too, i.e., a command-line prompt to execute the same C# program.

  • Here, you must write code to a text editor or simply copy the “Hello World” code to understand the execution process well.
  • The text file should be saved as hello world.cs
  • Now open the command-line prompt and type CSC hello world.cs to compile the program.
  • If compilation is done successfully, then it will take you to the next stage, the helloworld.exe executable file.
  • Now type hello World; on execution, it will display the final output on the screen.

Tip: Go through the .Net interview questions and answers for freshers as well as professionals to crack the .net interview on the first attempt!

Learn C# Basic Syntax

Identifiers – An identifier in C# is used to identify some class, members, functions, etc. Here are some rules to name classes in C#, like it should be started with a character only, not the digits. We cannot use any special symbol for the class declaration, but underscore (_) can be used if necessary.

Keywords - are pre-defined in any programming language and have significant meaning relevant to the code. There are two types of keywords in C sharp – 

  • Reserved keywords - That have special meaning in a program
  • Contextual keywords- Contextual keywords are usually used in the context of code.

Following are the reserved and contextual keywords

C# Data Types -The data types in C sharp are divided into three major categories – 

  • Value types, 
  • Pointer types, and 
  • Reference types. 

Value data types can accept value directly in the form of characters, integers, etc. Here is a complete list of value data types that C sharp programmers frequently use.

Reference Types – These data types don’t contain the actual value but store reference values for the variables. For example, Reference data types can represent memory locations that keep changing automatically.

Pointer types – These data types are used to store memory address, and it has the same capabilities as pointers in C language or C++ language. Here is a quick example of how to declare pointers in C sharp.

Type conversion in C sharp

Type conversion or typecasting is a popular programming feature where one data type is converted to another form as per the requirements. Here are two popular categories of type conversion in C sharp 

  • Implicit Type Conversion – These conversions are performed by C sharp safely. For example –Small integers are converted to large integers, or base classes are converted to derive classes and vice versa.
  • Explicit type conversion–These conversions are performed with the help of pre-defined functions, so it is named explicit type conversions. The following example shows how explicit conversions are performed-

Tip: The recruiters aren’t hiring .net developers in their team for just theoretical knowledge. Instead, they prefer candidates who have the required skill set to excel as a .NET developer. 

Therefore, the .net developer salary also depends on the candidate's skill set. It makes them different from other candidates. Different skill sets have various demands, and the salary is based accordingly. 

C sharp Constants, Variables, Literals, and Operators

C# Variables–Variable is a name given to the storage area that the programs can manipulate. A Variable has a specific data type representing the storage's size and nature. C sharp also has unique variables that come under the advanced programming section. Here is a quick review of how we can define variables in C sharp.Learn C# Programming Tutorial for Beginners

C # Constant– The constants in C sharp are the fixed values that cannot be changed throughout the program execution. The fixed value stored for the constant is termed as Literals. Constant may be declared as integers, constants, floating values, strings, etc. There are enumeration constants too that are used in advanced programming.

C# Operators–An operator in C# is a special symbol that guides the compiler to perform specific mathematical or logical calculations. The most popular operators defined in C# include –

  • Arithmetic operators,
  • Relational operators,
  • Bitwise operators,
  • Logical operators,
  • Assignment operators, and
  • Miscellaneous operators.
