Calros,

If you want to add a number, then you can use the static ToInt32 method
on the Convert class to convert your string to an integer. Then, you can
just perform your arithmetic.

When you want to convert it back to a string, then you can call ToString
on the int variable.

As for incrementing a letter, you can create a character array and then
increment the character by one in the array.

However, you have to have logic for when you get to the letter Z.

Then you can convert the character array back to a string.

Hope this helps.

What happens when "ABC" eventually becomes "ABZ"? Does the previous letters
get up'ed? Such as "ACA"? If so, what happens at "ZZZ"? Does it become
"AAAA" or "ZZZA"? Need more info if we are to help :)

Hi~
Thank for you point my problem, I consider that If I get the string of end
letter is"Z" I'll take ignore, in other word If I get string "ABZ" than keep
the string orginal "ABZ" or not do anything.

I just want to know how If I get "123" than get "124" thanks everybody, I
will appreaciate.

string s = "abc";
char subChar = s[2]; // last character
subChar++;
Console.WriteLine(s.Substring(0,2) + subChar);

Well if you do not know what to do in that case maybe you want to rethink
the entire thing over :)

Start with thinking why are you doing it and what you want from it.

Un Saludo,
