用来支持正则的类库中的部分算法?

这一个方法，改改就ok。。

//通过正则表达式，返回想要内容
public static string forumConects(string str)
{
string titlesTemp = "";
string regGetTitles = "<div id=\"postmessage(.*?)\" class=\"t_bigfont\">([\\s\\S]*?)</div>"; //正则表达式获取产品论坛标题
Regex regexGetTitles = new Regex(regGetTitles, RegexOptions.IgnoreCase);
MatchCollection mcGetTitles = regexGetTitles.Matches(str); //存放匹配的集合
for (int i = 0; i < mcGetTitles.Count; i++)
{
string titlesName = mcGetTitles[i].ToString();
string titlesNametmps1 = Regex.Replace(titlesName, regGetTitles, "$2", RegexOptions.Compiled | RegexOptions.IgnoreCase);
titlesTemp = titlesNametmps1;
}
