Formating a string

[John Smith]

What is the best way to format a string like

ABCDEFGHIJK

TO

ABC.DEF.GHI-JK

I found a lot of examples but I don't know which one is the best.....

thanks!

Hello Kevin,
just put a . after the 3rd letter, one more . after the 6th letter and a -
after the 9th letter.

so, XXX.XXX.XXX-XX

thanks!

Is it always that way? Is the unformatted string always 11 characters in
length?

If so, this will do it:

string strUnformatted = "ABCDEFGHIJK";
string strFormatted
= strUnformatted.Substring(0, 3) + "."
+ strUnformatted.Substring(3, 3) + "."
+ strUnformatted.Substring(6, 3) + "-"
+ strUnformatted.Substring(9);

Create a class with a static function which takes the unformatted string as
a parameter and returns the formatted string.

yes, it is aways 11 chars, so I should do this way then? using substring?

I thought there was a way using string.format or somthing....

thanks anyway!

You could do it with String.Format, but Mark's method is easier, and just as
good.
