using System.Text.RegularExpressions;

content = Regex.Match(content, "相关搜索(?<val>[\\s\\S]*?)search", RegexOptions.IgnoreCase).Groups["val"].Value.Replace("\r","").Replace("\n","");

MatchCollection TitleMatch = Regex.Matches(content, ">(?<val>[\\u4e00-\\u9fa5|\\w]*?)</a>", RegexOptions.IgnoreCase | RegexOptions.Multiline);

// System.Text.RegularExpressions.Group TitleMatch = Regex.Match(content, ">(?<val>[\\u4e00-\\u9fa5|\\w]*?)</a>", RegexOptions.IgnoreCase).Groups["val"];

textBox1.Text = TitleMatch[2].Groups["val"].Value;

//下面的是取得比较正确的一个

MatchCollection TitleMatch = Regex.Matches("2.5%-15.5%", @"[\d\.]+%", RegexOptions.IgnoreCase );

、、、、注意，这里就不用转意字符\了

return TitleMatch[0].ToString();

private string remax(string chars)
{

        string temp = "";
        MatchCollection TitleMatch2 = null;
       // MatchCollection TitleMatch = Regex.Matches("2.5%-15.5%", @"[\d\.]+%", RegexOptions.IgnoreCase );
        MatchCollection TitleMatch = Regex.Matches(chars, @"[\d\.]+%", RegexOptions.IgnoreCase);
        if (TitleMatch.Count > 0)
            temp = TitleMatch[TitleMatch.Count - 1].ToString();
        else if (TitleMatch.Count == 0)
        {
            TitleMatch2 = Regex.Matches(chars, @"\d+元", RegexOptions.IgnoreCase);
            if (TitleMatch2.Count > 0)
                temp = TitleMatch2[TitleMatch2.Count - 1].ToString();
        }

return temp;
}
