RegEx for CSV

After much searching, this is the best RegEx I can find for splitting a line of text from a CSV file:
(?:^|,)(\"(?:[^\"]+|\"\")*\"|[^,]*)

Here is the magical working code:

  protected virtual string\[\] SplitCSV(string line)
  {         System.Text.RegularExpressions.RegexOptions options = ((System.Text.RegularExpressions.RegexOptions.IgnorePatternWhitespace | System.Text.RegularExpressions.RegexOptions.Multiline) 
        | System.Text.RegularExpressions.RegexOptions.IgnoreCase);
     Regex reg = new Regex("(?:^|,)(\\\\\\"(?:\[^\\\\\\"\]+|\\\\\\"\\\\\\")\*\\\\\\"|\[^,\]\*)", options);
     MatchCollection coll = reg.Matches(line);
     string\[\] items = new string\[coll.Count\];
     int i = 0;
     foreach(Match m in coll)
     {
        items\[i++\] = m.Groups\[0\].Value.Trim('"').Trim(',').Trim('"').Trim();
     }
     return items;
  }
