C# codestring reg=@"(?<!d)\b\d+";

又快又严谨，严重无言...

(?<!d)\d*

要提取还是替换？

            string str = "d3,d4,d5,3,4,6,";
            Regex reg = new Regex(@"(?<!d)\b\d+");
            MatchCollection mc = reg.Matches(str);
            foreach (Match m in mc)
            {
                richTextBox2.Text += m.Value + "\n";
            }

[十八道胡同]

   string str = "d3,d4,d5,3,4,6,";
            Regex re = new Regex(@"(?<!d)\d,");
            MatchCollection mc = re.Matches(str);
            foreach(Match m in mc)
                Console.WriteLine(m.Value);
