Wondering how to learn C#? Then you’ve come to the right place. We will answer all your C# questions, such as: what are the features of C#? Is C# hard to learn? What are the best ways to learn C#? What’s the job market like for C# programmers? And much more. By the end of this article, you will know exactly how to learn C# easily.

What is C#?

C# (pronounced as C Sharp), developed by Microsoft, uses the .NET framework. It’s a multi-purpose programming language that is modern and object-oriented. 

C# is more of a blend of C and C++ programming languages. However, in contrast, the syntax of the C# language is expressive, simple, intuitive, and easy to understand. 

Complexities introduced by the C++ language are highly simplified by the C# language. This includes enumerations, nullable types, direct memory access, delegates, etc., which are also not found in Java.

C# is ranked as the 7th most popular programming language. While most of the programming languages are created to carry out a specific set of tasks, C# is a general-purpose programming language. 

You can use C# to work with databases, create high-speed graphics for video games, play audio/video effects, control connected devices, and more. 

C# is interpreted as well as compiled. Unlike C++ and Java, C# provides excellent screen handling support for Web as well as Desktops. This is where C# stands with respect to other popular programming languages.

Properties of C#

Before we move further ahead, let’s discuss a few properties of the C# programming language that will help you digest its popularity better.

  • It’s Safe

Data loss is not possible in C# because it does not support type conversion. Moreover, it supports non-nullable and nullable value types as well. As a result, developers can write code safely.

  • It’s Modern and Intuitive

C# was created with the sole aim that developers can access a general-purpose language that is easy to understand and can compete with other modern languages in terms of carrying out the functionalities. 

The C# programming language can develop applications and software for various fields and platforms, including Android, iOS, Web, or Windows.

  • It’s Open-Source and Free

C# is an open-source language developed by Microsoft; hence it’s free to use. It has a huge base of developers that contribute and are highly active and supportive. 

Applications of C#

C# is a middle-level language that makes it user-friendly, intuitive, and easy to understand. Moreover, C# has a faster execution time. That’s why it is used widely for embedded programming as well.

Apart from this, C# programming language is widely used to build large-scale applications for Windows, Desktop and Web applications, Games, Virtual Reality (VR), Database Applications, and other services for the Web. You can also use it to develop iOS and Android applications as well.

Features and Advantages of C#

Before discussing why you should switch over to C# from C++, Java, or other languages, let’s discuss a few features and advantages that C# brings to the table.

  • Fast: C# is a fast programming language and has a quick execution time.

  • Simple: C# doesn’t require you to include header files — it has a structured approach that allows you to break the problem into parts and has a rich set of libraries and data types.

  • Object-Oriented: It supports OOPS concepts that make maintenance and development easier. It supports all aspects of object-oriented programming such as inheritance, polymorphism, abstraction, encapsulation, interfaces, etc.

  • Type-Safe: It allows you to write and develop type-safe code, improving security. You will not be able to perform unsafe casts, such as converting a double data type to a boolean. It automatically initializes data types and objects as well as classes to zero or null values.

  1. Interoperability: It can interact well with other programming languages. This helps to increase the reusability of the code and create an efficient program. It can use COM objects irrespective of the language that’s used to write them. It can also call out any API.

  2. Structured: C# divides a large program into modules, procedures, or functions to solve specific problems. 

  3. Component-Oriented: C# is a component-oriented programming language, meaning it uses events, properties, attributes, methods, etc., to allow and create self-contained and described components called functionalities.

  4. Platform-Independent: Any platform that has .NET installed on it can run C#.

  5. Automatic Garbage Collection: The system does not get messed up or hanged during execution because C# has an automatic garbage collection that automatically removes dangling items during runtime.

  6. No Memory Leak: It has strong and high memory backup that helps in avoiding memory leakage, unlike C++.

Why Should You Learn C# in 2022?

Prerequisites for Learning C#

To start learning C# as a beginner, you need to have some basic concepts brushed up to learn C# quickly and efficiently. Some of the prerequisites include: 

  1. Basic computer knowledge such as working with command-line, file systems, and installing applications such as compilers, interpreters, etc.

  2. Knowledge of object-oriented programming. C# is an object-oriented programming language, which means that you will need to have a basic understanding of concepts like encapsulation, polymorphism, abstraction, inheritance, interfaces, etc.

  3. Basic knowledge of C, C++, or Java just to have a slight understanding of the syntax of C#. 

How to Install C#

to The best way to run C# is through the Visual Studio Code IDE. It has built-in support for debugging and running C# programs.

Let's see how to run a C# program through Visual Studio Code. For this, you will need to download the IDE from its official website. The installation is quite simple and intuitive. 

After you have installed the IDE, follow these steps to run a C# program. 

1. Create a new file with .CS extension. This is the extension for a C# file.

How to Learn C# in 2022: Roadmap

The next and the most important step is to figure out a learning path that will help you learn C# quickly and efficiently. Let’s try to list down the high-level topics that you will need to master the concepts of C#. In the prerequisites section, we have already discussed that you need to understand the Object-Oriented Programming Concept to get started with C#.

1. Syntaxes, Variables, and Data-Types

Learning the syntax is the basic step to getting started with any programming language, and the same can be applied for C#. You can learn how to declare variables, the different data types, comments, input-output, type-conversion, etc.

2. Conditionals and Loops

After you have grabbed the syntax, the next step is to learn branching and looping statements. Loops help you create a program that can automate repetitive tasks instead of running the same code manually multiple times. Conditionals help you to give a flow to the program. Some of the topics include: 

  • If/Else conditions
  • Switch statements
  • Comparison operators
  • Logical operators
  • For loops
  • For-each loops

3. Functions/Methods and Arrays

Functions, methods, or procedures allow you to group a piece of code to perform a specific function, such as adding two numbers, etc. To perform a specific operation multiple times, you don’t need to write the same code multiple times in different program sections. You can create a simple function for it and use it wherever you want. Arrays allow you to store lists of data.

Topics that you can learn in this section include:

  • Defining and calling methods
  • Parameters and arguments in methods
  • Method overloading
  • Creating, accessing, and manipulating arrays

4. Classes and Objects

These are a part of OOPS concepts. Classes encapsulate related data together, and objects provide instances to access data stored inside classes. This section teaches:

  • Classes
  • Objects
  • Access modifiers
  • Fields
  • Properties
  • Constructors
  • “This” keyword
  • Constructor overloading
  • Object dot notation

5. Interfaces and Inheritance

Inheritance allows you to inherit functions, variables of one or more classes, to another. Interfaces allow you to create classes like structures where you don’t need to define the methods, just declare them. At a later stage, when you require it, you can define these methods in their subclasses. Topics to be learned include:

  • Building interfaces
  • Parent/child classes
  • Accessing inherited components
  • Method overriding

Once you have learned all the basics, you can move forward to learn advanced concepts such as:

  • Polymorphism
  • Abstract classes
  • Data structures such as stacks, queues, hash tables, collections, etc.
  • ArrayList
  • File handling
  • Serialization
  • Database connection
  • Windows Form Applications 

Once you have mastered these topics, you are ready to move on to the next step. It’s very important to understand that mastering theory is not enough to learn any programming language. You need to get hands-on by creating as many projects of different levels to have a deeper understanding of the concepts. 

But before getting to the projects section, let’s discuss a few online resources that you can use to learn C# programming quickly and efficiently.
