Replicating Perl's unpack functionality in C#

[DJJohnnyG]

Hi,

I am trying to recreate a perl script in C# but have a problem creating a checksum value that a target system needs.

In Perl this checksum is calculated using the unpack function:
[code=perl]
while () {
$checksum += unpack("%32C*", $_);
}
$checksum %= 32767;
close(PACKAGE);
}[/code]

where PACKAGE is the .tar file input stream

I need to replicate this in C# but can't find a means of replicating that unpack function.

All help appreciated!

(I know there are much better checksum calculations available but can't change target system so can't change calculation)

My perl is a bit rusty, but it looks like unpack just pulls out a list of variables from a binary string.
%32C says to produce a 32bit checksum of the object instead of the object itself (Presumably the C just tells it to produce a "hex"-string by using unsigned characters?)

I guess you would have to find out what the checksum method they use is and implement that.
