foreach operating on 2 string[]

[john bailo]

Suppose

string in[], out[]

//both have three elements

foreach ( string str in in[] )
Console.Writeline( str );

writes all the strings in in[]

now i want to loop through both in and out using the same str counter in the
foreach.

how can i do this?

foreach (string str in in[] )
Console.WriteLine( str + " " + <here i want the corresponding out[]
elemement> );

Umm.. Well,.. you can use a *for* loop and take the length and since
both the strings are going to have the same length, just use [i]
syntax.. no?

The easiest way of doing it if you were going to do it a lot and really
wanted to keep the foreach syntax would be to create a new class which
took the two arrays and was enumerable, giving out a pair reference for
each iteration - the pair would contain the in and the out, if you see
what I mean.

Unless you're doing it a lot, however, it's probably easier (although
not as pleasant) to just use a normal for loop.

you could

but wouldn't it be cooler if you could increment another object
within a foreach ?

Wouldn't it be easier if you use Hashtable in .NET System.Collection?

Well, Maybe you might want to look at Hashtable or some such tuple
handlers. They might allow you to do something similar.
