How Can I Get a Complete List of Time Zone IDs for Use with C#'s `FindTimeZoneById()`?

C# FindTimeZoneById() List of time zone IDs used by the method

Introduction:

When dealing with time zones in C#, the TimeZoneInfo class provides a convenient way to access and manipulate time zone information. The FindTimeZoneById() method allows you to retrieve a TimeZoneInfo object for a specific time zone by its identifier. However, finding the complete list of all supported time zone identifiers can be challenging.

Access time zone ID list:

To get a complete list of time zone IDs, use the TimeZoneInfo method of the GetSystemTimeZones() class. This method returns a IEnumerable<TimeZoneInfo> collection containing all time zones supported by the operating system.

Code example:

The following code snippet demonstrates how to print a list of all time zone IDs using the GetSystemTimeZones() method:

<code class="language-csharp">using System;

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

Result:

When run on a Windows 7 workstation, the above code outputs the following list of time zone IDs:
