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)
{

Actually you should use classic for (;;) loop if you want to loop through an array. But the similar functionality that you have achieved with your PHP code can be achieved in C# like this with a Dictionary:

Dictionary values = new Dictionary();
values[0] = 5;
values[1] = 14;
values[2] = 29;
values[3] = 49;
// whatever...

foreach (int key in values.Keys)
{
    Console.WriteLine("{0} is assigned to key: {1}", values[key], key);
}
