I actually think that the PigLatin one was a lot easier, If you know your string arrays and defining functions it wasn't too bad. That way the quickest way of doing it or you could take out the function and do everything yourself. You have to let the code do the work for you.

Messy code, i'll admit, but I did lots of editing to this, I'll go back and tidy things up a bit more by combining a few things. I have a couple repeats that could be shortened with less code, but it's working, so now it's just the steps to tidy things up Smile

RE: .Net Coding Challenge #2 - Fragma - 04-18-2011

Yours is similar to mine Infinity. Although where you have "{0:X1}", you should change it to "{0:X2}".
This will mean that bytes with a value of 0 to F won't be missing their leading zero.

An example...
Here I have used my program, and your program, to find the MD5 hash of an image file.

Your program gave: 8AE1AB2A5D297E76458417FA1DD0

Whereas mine (using "{0:X2}") gave: 08AE1AB2A5D2097E0764058417FA1DD0

By the way guys.. Can I host the next challenge? Smile

A bit off topic but i had a great idea for the next contest but i forgot it --'
