Getting the array key in a 'foreach' loop

Question

How do I get the key of the current element in a foreach loop in C#?

For example:

PHP

foreach ($array as $key => $value)
{

If you want to get at the key (read: index) then you'd have to use a for loop. If you actually want to have a collection that holds keys/values then I'd consider using a HashTable or a Dictionary (if you want to use Generics).

Dictionary items = new  Dictionary();

foreach (int key in items.Keys)
{
  Console.WriteLine("Key: {0} has value: {1}", key, items[key]);
}

Hope that helps, Tyler
