Recursive function in action
using System;
public class FactorialTest
{
public static void Main( string[] args )
{
for ( long counter = 0; counter <= 10; counter++ )
Console.WriteLine( "{0}! = {1}",
counter, Factorial( counter ) );
}
public static long Factorial( long number )
{
if ( number <= 1 )
return 1;
else
return number * Factorial( number - 1 );
}
}
[/csharp]
Recursive Factorial method.
using System;
public class FactorialTest
{
public static void Main( string[] args )
{
for ( long counter = 0; counter <= 10; counter++ )
Console.WriteLine( "{0}! = {1}", counter, Factorial( counter ) );
}
public static long Factorial( long number )
{
if ( number <= 1 )
return 1;
else
return number * Factorial( number - 1 );
}
}

Use a recursive method, travel, to journey from start to finish
using System;
public class Journey {
private static String indent = “”;
public static void TakeOneStep(int step) {
Console.WriteLine(“{0}Taking step {1}”, indent, step);
}
public static void Move(int start, int finish) {
string oldIndent = indent;
Console.WriteLine(“{0}Starting move from {1} to {2}”, indent, start, finish);
if (start < finish) {
TakeOneStep(start);
indent += " ";
Move(start+1, finish);
indent = oldIndent;
}
Console.WriteLine("{0}Finishing move from {1} to {2}",indent, start, finish);
}
public static void Main(String [] args) {
Move(1, 10);
}
}
[/csharp]
Recursive sum method
public class SumPrices {
public static double Sum(double[] p, int start, int end) {
if (start < end)
return p[start] + Sum(p,start+1,end);
else return 0;
}
public static void Main() {
double[] prices = {1.3, 13.68, 314.919, 82.827, 363.949};
System.Console.WriteLine("The sum is {0:C}", Sum(prices,0,prices.Length));
}
}
