TimeZone.CurrentTimeZone.StandardName 给你个例子看看 using System; using System.Globalization; class TimeZoneDemo { static void Main( ) { const string dataFmt = "{0,-30}{1}"; const string timeFmt = "{0,-30}{1:yyyy-MM-dd HH:mm}"; Console.WriteLine( "This example of selected TimeZone class " + "elements generates the following \n" + "output, which varies depending on the " + "time zone in which it is run.\n" ); // Get the local time zone and the current local time and year. TimeZone localZone = TimeZone.CurrentTimeZone; DateTime currentDate = DateTime.Now; int currentYear = currentDate.Year; // Display the names for standard time and daylight saving // time for the local time zone. Console.WriteLine( dataFmt, "Standard time name:", localZone.StandardName ); Console.WriteLine( dataFmt, "Daylight saving time name:", localZone.DaylightName ); // Display the current date and time and show if they occur // in daylight saving time. Console.WriteLine( "\n" + timeFmt, "Current date and time:", currentDate ); Console.WriteLine( dataFmt, "Daylight saving time?", localZone.IsDaylightSavingTime( currentDate ) ); // Get the current Coordinated Universal Time (UTC) and UTC // offset. DateTime currentUTC = localZone.ToUniversalTime( currentDate ); TimeSpan currentOffset = localZone.GetUtcOffset( currentDate ); Console.WriteLine( timeFmt, "Coordinated Universal Time:", currentUTC ); Console.WriteLine( dataFmt, "UTC offset:", currentOffset ); // Get the DaylightTime object for the current year. DaylightTime daylight = localZone.GetDaylightChanges( currentYear ); // Display the daylight saving time range for the current year. Console.WriteLine( "\nDaylight saving time for year {0}:", currentYear ); Console.WriteLine( "{0:yyyy-MM-dd HH:mm} to " + "{1:yyyy-MM-dd HH:mm}, delta: {2}", daylight.Start, daylight.End, daylight.Delta ); } }

在网上找一个国家IP范围数据库,根据用户IP,判断他所在的国家,然后使用此国家的基本时区。
