正则取出数字

[bychgh]

用正则表达式分别取出字符串中的数字，如

aaaaaaa/bbbbbb/123/345.htm

分别取出123，和345

[huminghua]

一定要用正则吗？

[自由小菜园]

Regex.Matches("aaaaaaa/bbbbbb/123/345.htm", "\\d+",RegexOptions.Multiline);

[兔子-顾问]

foreach(Match m in Regex.Matches(@"aaaaaaa/bbbbbb/123/345.htm",@"\d+"))
{
    m.Value;//就是你要的数字
}

foreach (Match m in Regex.Matches(@"aaaaaaa/bbbbbb/123/345.htm", @"\d+"))
{
Response.Write(m.Value);

怎么分离开来2个数字

[不懂装懂]

 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;
            }

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？

[bychgh]

        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
