im building a snake game in C# for my coursework. Im currently working on detecting collision of snake's head into it's own body.

I was just wondering how to detect if var A's value is in_array of var B

I would have done this in PHP like this:

<?php

$headX = array();
$headX[0] = 5;

$headY = array();
$headY[0] = 5;

$bodyX = array();
$bodyY = array();
$bodyX[1] = 4;
$bodyY[1] = 5;
$bodyX[2] = 3;
$bodyY[2] = 5;
$bodyX[3] = 3;
$bodyY[3] = 5;

if((in_array($headX, $bodyX)) && (in_array($headY, $bodyY)))
{
echo 'Game Over';
}

?>
