[Robert Bravery]

HI all,

If I have a foreach loop, is there a way to tell what number of itteration I
am on during each loop

Thanks
Robert

The way the I would do it is have a variable that is incremented at the
end of the loop. They are probably other ways to do it though.

Hi,
Thats what I have at the moment. I thought there might have been a more
elegant way of doing it

Thanks
Robert

Not without an auxiliary variable. Foreach relies on iterators, and
the concept of .NET iterators doesn't include an iteration count.

Hello Robert,

Realization of foreach based on the IEnumerable/IEnumerator interfaces which
don't have members to get the number of the current iteration

You can check this interfaces in MSDN

It depends on the type you are dealing with.

foreach in the case of an array is special cased and will give you identical
code to a for loop.

I'm afraid you missed the point of this thread...

Not really .. if you are dealing with an array _don't_ use foreach if you
need a count as it produces the exact same thing as a for (including having
a counter) its just that you can't access it. Adding "your own counter" will
actually maintain 2 counters which is rather inefficient.

Cheers,

Greg
