Identifying last loop when using for each

Question

I want to do something different with the last loop iteration when performing \'foreach\' on an object. I\'m using Ruby but the same goes for C#, Java etc.

Answer 1

You could do something like that (C#) :

string previous = null;
foreach(string item in list)
{
    if (previous != null)
        Console.WriteLine("Looping : {0}", previous);
    previous = item;
}
if (previous != null)
    Console.WriteLine("Last one : {0}", previous);
