using System;
using System.Collections.Generic;
public class Demo {
public static void Main(string[] args) {
var subjects = new List<string>();
subjects.Add("Maths");
subjects.Add("Java");
subjects.Add("English");
subjects.Add("Science");
subjects.Add("Physics");
subjects.Add("Chemistry");
foreach (var sub in subjects) {
Console.WriteLine(sub);
}
}
}Output

Now to check whether a list is empty or not, use the Count property.
if (subjects.Count == 0)
Console.WriteLine("List is empty!");Now let us see the complete code.

public static void Main(string[] args) {
var subjects = new List<string>();
subjects.Add("Maths");
subjects.Add("Java");
subjects.Add("English");
subjects.Add("Science");
