Regular Expressions

string pattern = @"\s*(""[^""]*""|\S+)\s*";
var fields = Regex.Matches(input, pattern).Cast<Match>().Select(m=>m.Groups[1].Value);

1. ..."[^"]*"...: "..."
2. ...[^"]*"[^"]*"...: any number of non-"-char, followed by "..." from 1. above
3. ...(?:[^"]*"[^"]*")*...: any repetition of the group described in 2. above
4. ...^(?:...)*...: 3. above must match from the beginning of the text
5. ...^(?:...)*[^"]*...: 4. above, followed by any number of non-"-char
6. (?<=...) : match a space that is preceeded by the expression from 5. above; the (?<=...) is not part of the match

string pattern = @"\s*(""[^""]*""|\S+)\s*"; // maybe a more sophisticated pattern is
                                            // needed since the above expression seems
                                            // to match more,
                                            // but this is maybe an undesired side
                                            // effect of the complicated expression

^(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[^a-zA-Z0-9]).{6,}$

1. ^ checks for the start of the input string.
2. (?=.*[a-zA-Z]) checks that there are at least one letter.
3. (?=.*[0-9]) checks that there are at least one digit.
4. (?=.*[^a-zA-Z0-9]) checks that there are at least one special character (not a letter nor digit).
5. .{6,} checks that there are at least 6 characters.
6. $ checks for the end if the input string.
