Last month I posted an answer on CodeProject to a pretty logical question. I then thought of sharing it as a Tip/Trick.
How to swap alternate characters of a string?
In case the length of string is an odd number, then the last character should maintain its original position as below.
string input = "AXBYCZ"; StringBuilder output = new StringBuilder();
char characters = input.ToCharArray();
for (int i = 0; i < characters.Length; i++)
if (i % 2 == 0)
if((i+1) < characters.Length )
output.Append(characters[i + 1]);
Happy to see other logical solutions for this.
