Do you want the random number to be the *same* whenever all the input values are the same? — Kerrek SB, Jul 06 '11 at 10:14
BTW, there's no such thing as "c sharp". The language is named "C#". — John Saunders, Jul 28 '11 at 04:48

Barcodes are simply fonts, you will need to download and incorporate a barcode font into your application.

Generate a random number between 0 and 100

Random random = new Random();
int randomNumber = random.Next(0, 100);

Note: A couple of things that caught me out were that some barcode formats require starting/closing characters such as an asterisk (easily added to your random number). Also some output formats such as Word altered the width of the font when printed which caused some scanner problems. Be sure to experiment. – Kynth Jul 06 '11 at 10:29

Be careful, instances of `Random` created in quick succession(withing a few milliseconds) return the same sequence of random numbers. – CodesInChaos Jul 06 '11 at 11:40

Barcodes aren't simply fonts. There are different formats of barcodes with different requirements such as start and stop characters, check digits and may be restricted in terms of the characters they may contain. This varies between the different specifications of barcodes. – Jason Jul 07 '11 at 09:01

First you should choose which barcode format to use (http://en.wikipedia.org/wiki/Barcode#Linear_barcodes). Once you know this you can use something like the Barcode Image Generation Library to generate your barcode image simply. This library can handle many different barcode specifications.

You may want to try Barcode.dll for barcode rendering:

It includes WinForms control - just drag & drop.

Please note that this is a commercial product I developed.
