Your question isn't very clear. Are you trying to add spaces between words?If so, then you can use
.PadLeft(20, " ")
.PadRight(20, " ")
when concating a word, if there is supposed to be a total of 20 characters. If you want the word and then 20 characters, you could just concat the word and then concat " " which is twenty spaces.
] is the MSDN info on PadLeft if you want to research it more.
