How to replace every char in a string value with the next char?

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.

You can convert the string to a char[], modify each char as needed, and convert the result back to a string as follows:

char[] chars = "ABC".ToCharArray();
for (int i = 0; i < chars.Length; i++)
{
    chars[i] += (char)2;
}
string result = new string(chars);
//    result == "CDE"

All you need to do is get the individual char from the string e.g.

string a = "aba";
char b = a[0]; //the value is equal to 'a'


Console.WriteLine((char)((int)b + 1));

then convert the char into an int and increament it then convert it back to a char

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[\
