What value should I pass into TimeZoneInfo.FindSystemTimeZoneById(String)?

Question

I want to use the TimeZoneInfo.FindSystemTimeZoneById(String) method, but I don't know what values to use as the input?

Where can I get a list of values for id required for FindSystemTimeZoneById?

Here is the list in Windows 8 (I extracted from Windows Registry)

You can fetch them from a static list in the TimeZoneInfo class

var infos = TimeZoneInfo.GetSystemTimeZones(); foreach (var info in infos) {     Console.WriteLine(info.Id); } 

Example:

  var tzInfo = TimeZoneInfo.FindSystemTimeZoneById("New Zealand Standard Time"); 

Or if you just want a list of the timezone id's like DJ KRAZE suggested

  var timeZoneIds = TimeZoneInfo.GetSystemTimeZones().Select(t => t.Id);
