请教匹配语句的写法和引用匹配集值的方法

Question

string code = "fuid=19064515" class="sl">萧大</a><br />
                        已住1小时47分</div>"

这个字符串带了换行回车，我想匹配 19064515 萧大 1小时47分

Regex regex = new Regex("fuid=(?<uid>\\d+)\" class=\"sl\">(?<name>.{1,20})</a><br />\n\r .{0,25}已住(?<time>.{1,100})</div>");

MatchCollection matchs = regex.Matches(code);

每回获取的值都是空，这个匹配语句应该怎么写？

还有，除了用下面这个方法引用匹配集的值

还有别的方法吗？

foreach (Match m in matchs)
            {
                string liveuid=m.Groups["uid"].Value;
                if (liveuid == tempuid)
                {
                    time = m.Groups["time"].Value;
                }
            }

修改下面的代码实现你的需求，读一下Ｒｅｇｕｌａｒ　Ｅｘｐｒｅｓｓｉｏｎ的文章：

 private void button1_Click(object sender, EventArgs e)
        {
            string code = "fuid=19064515\" class=\"sl\">萧大</a><br />已住1小时47分</div>";
            Regex rex = new Regex(@"fuid=\d{8}\""\s*class=\""sl\""\>萧大");
            MatchCollection matchs = rex.Matches(code);
            MessageBox.Show(matchs.Count.ToString());
        }

Answer 2

Regex regex = new Regex("fuid=(?<uid>\\d+)\" class=\"sl\">(?<name>.{1,20})</a><br />\\s* .{0,25}已住(?<time>.{1,100})</div>");

MatchCollection matchs = regex.Matches(code);

我后来QQ上找人问了，用 \\s* 能够替换 换行回车
