string html = sr.ReadToEnd();
string time = GetRegexStr(html, "(?<=baidu_time\\().*?(?=\\))").Substring(0, 10);//这里是时间戳 不是时间 要转换
stream.Dispose();
sr.Dispose();
DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
long lTime = long.Parse(time + "0000000");
TimeSpan toNow = new TimeSpan(lTime);
return dtStart.Add(toNow);
}
private static string GetRegexStr(string html, string regex)
{
Regex reg = new Regex(regex);
string result = reg.Matches(html)[0].Value;
return result;
