Answer 1

private void getRoom()
{
string strHtml = "<tr class='a1'>"
+ "<td width='84' rowspan='1' bgcolor='#EFF6FB'><div align='center'>13层</div></td> "
+ "<td height='68' width='140' bgcolor='#EFF6FB'><div align='center'>房号：13A</div> <div align='center'><a href='housedetail.aspx?id=925352' target=_blank><img src='imc/b2.gif' border='0'></a></div></td>"
+ "<td height='68' width='140' bgcolor='#EFF6FB'><div align='center'>房号：13B</div> <div align='center'><a href='housedetail.aspx?id=925353' target=_blank><img src='imc/b1_2.gif' border='0'></a></div></td></tr>";

string strKey = @"<tr class='a1'>[\s]*<td[.\s][^>]+><div align='center'>([\d]+层)</div></td>([\w\W]+)</tr>";
string strSubKey = @"<td[\w\W][^>]+><div align='center'>(房号：[\d]{2}[A-Za-z]{1})</div>[\s]*<div align='center'><a href='([\w\W][^']+)'";

Regex r = new Regex(strKey);
Regex rSub = new Regex(strSubKey);
if (r.IsMatch(strHtml))
{

MatchCollection mc = r.Matches(strHtml);
foreach (Match m in mc)
{
//层次
Console.WriteLine(m.Result("$1"));
this.textBox1.AppendText(m.Result("$1") + Environment.NewLine);
//房间号
string strRooms = m.Result("$2");
if (rSub.IsMatch(strRooms))
{
MatchCollection mcSub = rSub.Matches(strRooms);
foreach (Match ms in mcSub)
{
Console.WriteLine(ms.Result("$1"));
this.textBox1.AppendText(ms.Result("$1") + Environment.NewLine);
Console.WriteLine(ms.Result("$2"));
this.textBox1.AppendText(ms.Result("$2") + Environment.NewLine);
}
}
}
}

}

Answer 2

href='[^']+'
src='[^']+'

具体形式按你的Regex引擎来定，有可能是
href='(?[^']+)'
src='(?[^']+)'
