从服务器获取当前日期时间，并将其转换为本地时间在C＃ [英] Get current date time from server and convert it into local time in c#

问题描述

帮助：我有是有在GMT-07.00小时时间的服务器。我的本地时间为GMT +05.30小时。我需要从服务器获取当前日期和时间，此日期和时间转换成我的本地时间。我试过很多代码，但仍没有找到这样的连续方式。 。有人可以请帮我

Help: I have a server which is having time in GMT-07.00 hours. My local time is GMT+05.30 hours. I need to get current date and time from server and convert this date and time into my local time. I have tried many codes, but still have not found a successive way of doing this. Can somebody please help me out.

string zoneId = "India Standard Time";
TimeZoneInfo tzi = TimeZoneInfo.FindSystemTimeZoneById(zoneId);
DateTime result = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, tzi);
DateTime cu = result.ToUniversalTime();
DateTime cur = cu.ToLocalTime();

我已经尝试了所有上面的方法，我依然没有得到正确的答案。假如我目前的本地时间为09月2014年下午12时51分零零秒，然后我的服务器时间会从我的本地时间12.30小时不同，即减去12小时，从我的本地时间30分钟，得到我的服务器时间。我需要从服务器时间让我的本地时间。怎样才可以acheived？请建议我一些解决办法..预先感谢您的回答

I have tried all the above methods, still I'm not getting the correct answer. Suppose my current local time is 09-Mar-2014 12:51:00 PM, then my server time would be 12.30 hours different from my local time, ie subtract 12 hours and 30 minutes from my local time to get my server time. I need to get my local time from the server time. How can it be acheived?? Please suggest me some solutions.. Thanks in advance for your answers

推荐答案

不需要知道服务器的时区。如果服务器的时间设置是正确的，你可以试试这个：

no need to know server time zone. if the server time setting is correct you can try this :

DateTime serverTime = DateTime.Now; // gives you current Time in server timeZone
DateTime utcTime = serverTime.ToUniversalTime; // convert it to Utc using timezone setting of server computer

TimeZoneInfo tzi = TimeZoneInfo.FindSystemTimeZoneById("India Standard Time");
DateTime localTime = TimeZoneInfo.ConvertTimeFromUtc(utcTime, tzi); // convert from utc to local

在当地检查，更改您的计算机时区，以配合您的服务器。然后运行该代码。我检查，它的做工精细

to check it locally , change your computer timezone to match your server. then run the code. I check and it's working fine.

的 更新：的

update:

的前两行，可以如以下混合成一行。具有更好的性能：

the first two lines can be mixed into one line as below . that has a better performance :

DateTime utcTime = DateTime.UtcNow;
