using LINQ you can do:

string str = "the stock overflow in very good website";

string separator = "...";
string joinedString = string.Join("", (str.Split()
                      .Select(r=> r + separator +
                                   (string.Join(separator, r.ToCharArray()))
                                   +separator)));
Console.WriteLine(joinedString);

(By the way its stack overflow)

Ouput would be:

the...t...h...e...stock...s...t...o...c...k...overflow...o...v...e...r...f...l.. .o...w...in...i...n...very...v...e...r...y...good...g...o...o...d...website...w. ..e...b...s...i...t...e...

(Remember to include using System.Linq;)
