C# (pronounced "see sharp") is a computer programming language. It is developed by Microsoft. It was created to use all capacities of the .NET platform. The first version was released in 2001. C# is a modern language in active development, with the most recent version at time of writing being C# 13, which was released in June 2024 alongside .NET 9.[2] C#'s development team is led by Anders Hejlsberg, the creator of Delphi.

Execution Platform

[change | change source]

Today, C# can be run on most platforms (Windows, Linux, macOS, etc.) without changing the source code. C# can be run on the Xbox 360 platform with a special framework.

C# code is similar to C++ and Java code. The CLR (Common Language Runtime) is needed in order to run a C# program.[3]

"Hello, World!" example

[change | change source]
/* This is a simple program in C#. 
 * It simply shows "Hello, World!" on the screen.
 */
using System;
namespace HelloWorld
{
  class Hello
  {
    static void Main()
    {
      Console.WriteLine("Hello, World!");
      
      // The piece of code below is optional, but is needed to prevent the program from closing immediately.
      
      Console.WriteLine("Press any key to exit.");
      Console.ReadKey();
    }
  } 
}

Basic input example

[change | change source]
/* 
 * This program asks for input from the user, i.e. a name. It then prints "Hello [name]", replacing [name] with whatever the person typed in.
 */
using System;
namespace HelloWorld
{
  class Hello
  {
    static void Main()
    {
      Console.WriteLine("Hello, please type in your name:");
      string name = Console.ReadLine();
      Console.WriteLine("Hello {0}",name);
      Console.ReadKey();
    }
  } 
}
