如上所示：用正则表达式匹配 <a href="http://www.m1905.com/yx/film/c1p2.html">2</a> <a href="http://www.m1905.com/yx/film/c1p3.html">3</a>这部分内容里a标签href上的内容 即：http://www.m1905.com/yx/film/c1p2.html

Answer 1

            Dictionary<string, string> dic = new Dictionary<string, string>();
            MatchCollection m = Regex.Matches(input, @"(?i)<a[^href]*\s*href=""([^>]+)"">(.*?)</a>");
            foreach (Match mx in m)
            {              
                dic.Add(mx.Groups[1].Value, mx.Groups[2].Value);
                Console.WriteLine(mx.Groups[1].Value + "\t" + mx.Groups[2].Value);
            }
