Question

If I have a string variable like this:

string f = "ABC";

I want to make it like this:

f="CDE"

This means that I want to take every char in this string and increase it to the next 2 values, if I have ‘a’ I want to change it to ‘c’ and so on.

Answer 1

Following will increment the character to + 2, Not sure what you want when then characters are ending character in the alphabets.

string f = "ABC";
string result = new string(f.Select(r =>(char) (r + 2)).ToArray());

For string ABC result will be CDE, but for string XYZ result will be Z[\
