MarHope you are good! You are landed to the page because you are a beginner in the C sharp programming and wanted to learn C# Programming step by step from scratch. Well, you have landed in the right place finally and we have compiled a C# tutorial for beginners carefully after reading out multiple books and reference links. Our C# tutorial is 100 percent result-driven for the beginners that will help you in getting started with C# basic concepts.
If you are a beginner and interested in learning a new language, C sharp is the right choice to start your career. C sharp offers wonderful memory management techniques and solid safety types as compared to other programming languages. The dot net framework in C# has a robust set of class libraries to work with the file systems, security principles, and much more.
C sharp is a highly popular programming language like Java and Microsoft keep updating language features from time to time. With the release of the dot net core framework, C sharp will be in huge demand by the year 2018. This programming language is easy to learn and understand that helps you in designing a variety of software applications quickly. Here are a few highlights that make C sharp widely used programming language –
Before starting with C# programming, it is necessary to understand the difference between three popular terms – Framework, Programming Language, and IDE. In most of the cases, all of these terms are used interchangeably by beginners without knowing their actual meaning and significance. Visual Studio is an IDE, .NET is a framework, and C# is a programming language.
The .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.
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. This code management and automation techniques are offered by the IDE. This may be difficult to work with all the utilities in beginning, but things will get smoother as soon as you become more familiar with them.
Before we switch to advanced programming concepts, we should study programming structure first. A C# program consists of the following parts – Namespace, comments, class, class methods, statements, expressions and 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]
This is the right time to discuss on each and every concept of the program in detail –
From the above discussion, you are ready to write a short program in C#. 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.
If you are not interested in Visual Studio IDE then there is one other option too i.e. command-line prompt to execute the same C# program.
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–Keywords are pre-defined in any programming language and they have significant meaning relevant to the code. There are two types of keywords in C sharp – The first category is reserved keywords and the other is contextual keywords. Contextual keywords are normally used in the context of code.
The data types in C sharp are divided into three major categories – value types, pointer types, and reference types. Value data types are able to accept value directly in the form of characters, integers etc. Here is a complete list of value data types are frequently used by the C sharp programmers.
Reference Types – These data types don’t contain the actual value but they store reference value to the variables. For example, Reference data types can be used to represent memory location that keeps 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 how to declare pointers 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 –

C# Variables–Variable is a name given to the storage area that can be manipulated by the programs. A Variable has a specific data type that represents size and nature of the storage. C sharp also has special variables that come under advance programming section. Here is a quick review how we can define variables in C sharp.
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 in the form of 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 compiler to perform specific mathematics or logical calculations. The most popular operators defined in C# includes –
