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
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.
