How to get all the Time Zones in asp.net?

In the following example, I will show you how to get all the system timezones and bind them to a dropdownlist in Asp.net.
Step-1: Add a dropdownlist to your webpage. Lets its ID is "ddlTimeZone".

Step-2: Add 'using System.Collections.ObjectModel;' namespace to the .aspx.cs page.

Step-3: ReadOnlyCollection<TimeZoneInfo> timeZones = TimeZoneInfo.GetSystemTimeZones(); returns all the TimeZones.

Write the following method to select all the Time Zones and bind them to dropdownlist.

        public void GetTimeZones()

        {

            ReadOnlyCollection<TimeZoneInfo> timeZones = TimeZoneInfo.GetSystemTimeZones();

            ddlTimeZone.DataSource = timeZones;

            ddlTimeZone.DataBind();

            ddlTimeZone.Items.Insert(0, "Select");

        }

Step-4: Call this method wherever you need to bind the dropdown.
