DateTime dt;
WebRequest wrt = null;
WebResponse wrp = null;
try
{
wrt = WebRequest.Create("http://www.time.ac.cn/timeflash.asp?user=flash");
wrt.Credentials = CredentialCache.DefaultCredentials;
wrp = wrt.GetResponse();
StreamReader sr = new StreamReader(wrp.GetResponseStream(), Encoding.UTF8);
string html = sr.ReadToEnd();
sr.Close();
wrp.Close();
int yearIndex = html.IndexOf("<year>") + 6;
int monthIndex = html.IndexOf("<month>") + 7;
int dayIndex = html.IndexOf("<day>") + 5;
int hourIndex = html.IndexOf("<hour>") + 6;
int miniteIndex = html.IndexOf("<minite>") + 8;
int secondIndex = html.IndexOf("<second>") + 8;
问题是这个程序只执行到这，下面就不执行了，怎么回事啊，急求
string year = html.Substring(yearIndex, html.IndexOf("</year>") - yearIndex);
string month = html.Substring(monthIndex, html.IndexOf("</month>") - monthIndex); ;
string day = html.Substring(dayIndex, html.IndexOf("</day>") - dayIndex);
string hour = html.Substring(hourIndex, html.IndexOf("</hour>") - hourIndex);
string minite = html.Substring(miniteIndex, html.IndexOf("</minite>") - miniteIndex);
string second = html.Substring(secondIndex, html.IndexOf("</second>") - secondIndex);
dt = DateTime.Parse(year + "-" + month + "-" + day + " " + hour + ":" + minite + ":" + second);
}
catch (WebException)
{
return DateTime.Parse("2013-1-1");
}
catch (Exception)
{
return DateTime.Parse("2013-1-1");
}
finally
{
if (wrp != null)
wrp.Close();
if (wrt != null)
wrt.Abort();
}
return dt;
} 是报什么错
