Can this be simplified to a one liner? Feel free to completely rewrite it as long as secureString gets initialized properly.
SecureString secureString = new SecureString ();
foreach (char c in "fizzbuzz".ToCharArray())
{
secureString.AppendChar (c);
}
You could use Linq:
"fizzbuzz".ToCharArray().ToList().ForEach(p => secureString.AppendChar(p));
