rideronix, just do what tlhIn`toq told you to do in post #11

string someArgs = "Yogi Bear"; // a string is a char[]

foreach (char letter in someArgs)
{
    // do something with the letter(witch is now of type char but you need an int
}

see how foreach works

Or you could use the ToCharArray(), like

//Now the array contains every char in the value string
char[] array = value.ToCharArray();

I'm trying but only with this:

        static void Main(string[] args)
        {
            foreach (char letter in args[])
           {
           }
        }

I get the "args[]" underlined saying: "Value expected" and if I remove the "[]" it underlines foreach and says can't convert type string to char.

I did a bit of research and found this.
Check it out.

For the love of Pete, listen to what you're being told so you actually LEARN something!

string[] args

args is an array of string. As you've been told repeatedly.

Each of those strings in the array is an array of chars. So FIRST you need to go through each element of the array of strings to get the word, and once you have the word (the string) you can go through THAT array char by char.

Thank you that was clear !

I got the conversion right but when I try to unconvert.

Convert:

        static void Main(string[] args)
        {
            foreach (string letter in args)
            {
                for ( int n = 0; n < args.Length; n++)
                {
                    char lettre = letter[n];
                    Convert.ToInt32(lettre);
                    int rot13 = (int)lettre;

Unconvert:

                rot13 = (char)lettre;
                letter[n] = lettre; // Error here, I guess you can't modify an array like this... Do I need make a new array ?

How can I convert backwise ?

Problem solved.

                lettre = (char)rot13;
                Console.Write(lettre);

Works perfectly. However it display each new string one under another, how can I manage not to do this ? I wrote "Console.Write()" and not "Console.WriteLine()" but doesn't seem to change anything...

Recompile again. Be sure you are running the code with the Console.Write() keeps everything on the same line.

Thanks all done. Now I've ran into another problem but I'll make a new post since it's not really related.
