Hello @mzucker
use this code
Convert.ToChar(Convert.ToUInt16("@"c)+4)
you can also start with A but then to get D you’ll have to add 3
Convert.ToChar(Convert.ToUInt16("A"c)+3)
Use what suits you the best !!!
As @DanielMitchell said below the above could work for 26 letters.You could always get two letter by using an IF condition and assigning the above code twice with a + sign like this
Convert.ToChar(Convert.ToUInt16("A"c)+3)
+Convert.ToChar(Convert.ToUInt16("A"c)+3)
So If the digits are higher then I would suggest you to use @DanielMitchell link i tried the logic and methods used in that link and it works flawlessly.
Check the workflow below it contains logic used in that link
