In C#, we can use foreach to loop enumerable variables. For example the following code snippet loops through the string enumerable:
var items = new []{"Hello","World","!"} as IEnumerable<string>;foreach(var item in items) Console.WriteLine(item);
In some scenarios, it might be helpful to get the index too. This code snippet shows one approach to implement that.
Code snippet
var items = new []{"Hello","World","!"} as IEnumerable<string>;foreach(var (item, i) in items.Select((item, i)=> (item, i))) Console.WriteLine("{0:000} - {1:%s}", i, item);
The above code snippet utilize SelectLINQ extension method.
Output:
000 - Hello
001 - World
002 - !
