In C#, how do I get a list of Timezone IDs to use with FindTimeZoneById()?

Problem

Please direct me to a comprehensive list of all the timezones referred to by the id anticipated in TimeZoneInfo. FindTimeZoneById()? I’ve searched through the.NET docs but can’t seem to find a list.

Here’s a complete list of programs and their outcomes.

The code:

using System;

namespace TimeZoneIds
{
    class Program
    {
        static void Main(string[] args)
        {
            foreach (TimeZoneInfo z in TimeZoneInfo.GetSystemTimeZones())
            {
                Console.WriteLine(z.Id);
            }
        }
    }
}

On my Windows 7 computer, the TimeZoneId results are as follows:

If you’d want an HTML select with the Windows time zones included, go here.

You can, of course, generate the options in Razor by looping through TimeZoneInfo. GetSystemTimeZones()

Solution #5

From MSDN

ReadOnlyCollection<TimeZoneInfo> zones = TimeZoneInfo.GetSystemTimeZones();
Console.WriteLine("The local system has the following {0} time zones", zones.Count);
foreach (TimeZoneInfo zone in zones)
   Console.WriteLine(zone.Id);
