本文介绍了一种通过网络请求获取指定股票ID对应的股票市场行情数据的方法。该方法使用正则表达式从特定网站中解析所需的股票信息，并进行了一系列的数据清洗工作，如去除HTML标签、替换特殊字符等。

public string getnews_gshq(string stockid)
{
if(stockid.Length>6)
{
arsr="";
}
else
{
switch(int.Parse(stockid.Substring(0,1)))
{
case 0:
arsr="szag";
break;
case 2:
arsr="szbg";
break;
case 6:
arsr="shag";
break;
case 9:
arsr="shbg";
break;
default:
break;
}
}
stockurl="http://www.stockstar.com/scripts/quoteISAPI.dll?MFCISAPICommand=dghq&code="+arsr+stockid;

regexstr=" <tr//s*class=e02//s*height=.*>..* </table>//s*. <p>";

WebRequest request = WebRequest.Create(stockurl);
WebResponse response = request.GetResponse();
Stream resStream = response.GetResponseStream();
StreamReader sr = new StreamReader(resStream, System.Text.Encoding.Default);
Regex regex_Stock=new Regex(regexstr,RegexOptions.IgnoreCase|RegexOptions.Singleline);
MatchCollection mcoll= regex_Stock.Matches(sr.ReadToEnd());
string[] result=new string[mcoll.Count];
StringBuilder resbud=new StringBuilder();
for(int i=0;i <mcoll.Count;i++)
{
result[i]=mcoll[i].Value;
result[i]=Regex.Replace(result[i],@" ","");
//result[i]=Regex.Replace(result[i],@"/["," <");
//result[i]=Regex.Replace(result[i],@"/]",">");
result[i]=Regex.Replace(result[i],@" <[""A-Za-z0-9=#':;_/./-/%&?]*>",""); //过滤HTML标签
//result[i]=Regex.Replace(result[i],@" <[A-Za-z0-9=#':;_/./-/]*>",""); //过滤HTML标签
result[i]=Regex.Replace(result[i],@"/[[/u4e00-/u9fa5]*/]","");
result[i]=Regex.Replace(result[i],"/r","/r/n");
result[i]=Regex.Replace(result[i],"/n","/r/n");
result[i]=Regex.Replace(result[i],"/r/n/r/n","|");
result[i]=Regex.Replace(result[i],"//s*","");
resbud.Append(result[i].ToString());
}
resStream.Close();
sr.Close();
string[] gshq=resbud.ToString().Split('|');
int n=0;
for(int j=0;j <gshq.Length;j++)

}

return text1;
