'''C#''' (pronounced "see sharp") is a [[computer]] [[programming language]]. It is developed by [[Microsoft]]. It was created to use all capacities of the [[.net framework|.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.<ref>{{Cite web|last=BillWagner|date=2024-07-03|title=What's new in C# 13|url=https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-13|access-date=2024-07-26|website=learn.microsoft.com|language=en-us}}</ref> C#'s development team is led by [[Anders Hejlsberg]], the creator of Delphi.

== Execution Platform ==
*The [[Microsoft]] [[.NET]] platform;
*Free implementation of C# and [[.NET]] like [[Mono (software)|Mono]] developed by [[Novell]], or [[dotGNU]] developed by the [[Free Software Foundation]].

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

== Syntax ==
C# code is similar to [[C++]] and [[Java (programming language)|Java]] code.  The '''CLR''' ([[Common Language Runtime]]) is needed in order to run a C# program.<ref>{{cite book |title=Collected Computer Programming Problems in Visual C#.Net, [[Hary Gunarto]]  |publisher=Tech Publication, Singapore |isbn=978-9812141743 |year=2007}}</ref>

=== "Hello, World!" example ===
<syntaxhighlight lang="csharp">
/* 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();
    }
  } 
}

</syntaxhighlight>

=== Basic input example ===
<syntaxhighlight lang="csharp">
/* 
 * 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();
    }
  } 
}

</syntaxhighlight>
