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)
{
             


        

Answer 1

I answered this in another version of this question:

Foreach is for iterating over collections that implement IEnumerable. It does this by calling GetEnumerator on the collection, which will return an Enumerator.

This Enumerator has a method and a property:

* MoveNext()
* Current

Current returns the object that Enumerator is currently on, MoveNext updates Current to the next object.

Obviously, the concept of an index is foreign to the concept of enumeration, and cannot be done.

Because of that, most collections are able to be traversed using an indexer and the for loop construct.

I greatly prefer using a for loop in this situation compared to tracking the index with a local variable.

How do you get the index of the current iteration of a foreach loop?
