本文实例讲述了C#实现从网络同步标准北京时间的方法。分享给大家供大家参考。具体分析如下：

这段C#代码可以从http:///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; 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; }#endregion

希望本文所述对大家的C#程序设计有所帮助。
