Wie füge ich Elemente zu einer Liste in C# hinzu?

var teams = new List<string>();

teams.Add("US");
teams.Add("Canada");
teams.Add("India");
teams.Add("Australia");

using System;
using System.Collections.Generic;

public class Demo {
   public static void Main(string[] args) {

      var teams = new List<string>();
      teams.Add("US");
      teams.Add("Canada");
      teams.Add("India");
      teams.Add("Australia");
   
      Console.WriteLine("Elements...");
      foreach (var countries in teams) {
         Console.WriteLine(countries);
      }
   }
}
