Microsoft Visual C#

Implementation of programming language C#

Microsoft Visual C# is a reference implementation of C#, included in Visual Studio.

Examples:

Hello, World!:

Example for versions Microsoft Visual C# 2008 
using System;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello, World!");
    }
}

Factorial:

Example for versions Microsoft Visual C# 2008

This example uses recursive factorial definition. 

using System;

class Program
{
    static long Factorial(int n)
    {
        if (n == 0)
            return 1;
        else
            return n * Factorial(n - 1);
    }
    static void Main(string[] args)
    {
        for (int i = 0; i < 17; i++)
            Console.WriteLine("{0}! = {1}",i,Factorial(i));
    }
}

Fibonacci numbers:

Example for versions Microsoft Visual C# 2008

This example uses recursive definition of Fibonacci numbers. 

using System;

class Program
{
    static long Fibonacci(int n)
    {
        if (n < 3)
            return 1;
        else
            return Fibonacci(n - 1) + Fibonacci(n - 2);
    }
    static void Main(string[] args)
    {
        for (int i = 1; i < 17; i++)
            Console.Write("{0}, ", Fibonacci(i));
        Console.WriteLine("...");
    }
}
