            string paramStr="aaaaaaa/bbbbbb/123/345.htm";
Regex regNum = new Regex("[^0-9]");
Match matNum = regNum.Match(paramStr.ToLower());
string paramStrNoNumTemp="";
            int temp = -1;
            if (matNum.Success)
            {
                //进行匹配的字段在整个字符串中的起始位置
                int index = 0;
                MatchCollection mcNum = regNum.Matches(paramStr.ToLower());
                for (int i = 0; i < mcNum.Count; i++)
                {
                    if (mcNum[i].Index == 0)
                    {
                        index += mcNum[i].Length;
                        temp = 0;
                        continue;
                    }
                    string paramStrNoNum = "";
                    if (i > 0)
                        paramStrNoNum = paramStr.Substring(index, mcNum[i].Index - mcNum[i - 1].Index - mcNum[i - 1].Length);
                    else
                    {
                        paramStrNoNum = paramStr.Substring(index, mcNum[i].Index);
                    }
                    if (mcNum[i].Index!=temp+1)
                    {
                        paramStrNoNumTemp += ",";
                    }
                    paramStrNoNumTemp += paramStrNoNum;
                    index = index + mcNum[i].Length + paramStrNoNum.Length;
                    temp = mcNum[i].Index;
                }
            }

Answer 5

 Regex r=new Regex(@"\d+");
            MatchCollection m = r.Matches("aaaaaaa/bbbbbb/123/345.htm");
            for (int i = 0; i < m.Count; i++)
            {
                string s = m[i].Value;
            }

Answer 6

匹配结果本就是独立的2个match？你要的是？贴一下你要的结果？

Answer 7

        string content = "aaaaaaa / bbbbbb / 123 / 345.htm";
        string strRegex="\\d+";
        MatchCollection matchs = Regex.Matches(content, strRegex, RegexOptions.IgnoreCase | RegexOptions.Singleline);
        Response.Write(matchs[1].Value);//345
