Add one space after every two characters and add a character infront of every single character

Question

I want to add one space after every two characters, and add a character in front of every single character.

This is my code:

string str2;
str2 = str1         


        

Answer 1

May be you can try, if i right understand your request,

String.Length % 2

if result is 0, you done with first iteration, if not, just add a character infront of last one.
