      C# Tutorial

      C# (C-Sharp) is a programming language developed by Microsoft that runs on the .NET Framework.

      C# is used to develop web apps, desktop apps, mobile apps, games and much more.

      Examples in Each Chapter

      Our «Try it Yourself» editor makes it easy to learn C#. You can edit C# code and view the result in your browser.

      Example

      using System; namespace HelloWorld < class Program < static void Main(string[] args) < Console.WriteLine("Hello World!"); >> >

      Click on the «Run example» button to see how it works.

      We recommend reading this tutorial, in the sequence listed in the left menu.

      Introduction to C#

      Welcome to the introduction to C# tutorials. These lessons start with interactive code that you can run in your browser. You can learn the basics of C# from the C# 101 video series before starting these interactive lessons.

      The first lessons explain C# concepts using small snippets of code. You’ll learn the basics of C# syntax and how to work with data types like strings, numbers, and booleans. It’s all interactive, and you’ll be writing and running code within minutes. These first lessons assume no prior knowledge of programming or the C# language.

      You can try these tutorials in different environments. The concepts you’ll learn are the same. The difference is which experience you prefer:

      • In your browser, on the docs platform: This experience embeds a runnable C# code window in docs pages. You write and execute C# code in the browser.
      • In the Microsoft Learn training experience. This learning path contains several modules that teach the basics of C#.
      • In Jupyter on Binder. You can experiment with C# code in a Jupyter notebook on binder.
      • On your local machine. After you’ve explored online, you can download the .NET SDK and build programs on your machine.

      All the introductory tutorials following the Hello World lesson are available using the online browser experience or in your own local development environment. At the end of each tutorial, you decide if you want to continue with the next lesson online or on your own machine. There are links to help you set up your environment and continue with the next tutorial on your machine.

      Hello world

      In the Hello world tutorial, you’ll create the most basic C# program. You’ll explore the string type and how to work with text. You can also use the path on Microsoft Learn training or Jupyter on Binder.

      Numbers in C#

      In the Numbers in C# tutorial, you’ll learn how computers store numbers and how to perform calculations with different numeric types. You’ll learn the basics of rounding, and how to perform mathematical calculations using C#. This tutorial is also available to run locally on your machine.

      This tutorial assumes that you’ve finished the Hello world lesson.

      Branches and loops

      The Branches and loops tutorial teaches the basics of selecting different paths of code execution based on the values stored in variables. You’ll learn the basics of control flow, which is the basis of how programs make decisions and choose different actions. This tutorial is also available to run locally on your machine.

      This tutorial assumes that you’ve finished the Hello world and Numbers in C# lessons.

      List collection

      The List collection lesson gives you a tour of the List collection type that stores sequences of data. You’ll learn how to add and remove items, search for items, and sort the lists. You’ll explore different kinds of lists. This tutorial is also available to run locally on your machine.

      This tutorial assumes that you’ve finished the lessons listed above.

      101 Linq Samples

      This sample requires the dotnet-try global tool. Once you install the tool, and clone the try-samples repo, you can learn Language Integrated Query (LINQ) through a set of 101 samples you can run interactively. You can explore different ways to query, explore, and transform data sequences.
