How to add integer values to a C# list?

To add integer values to a list in C#, use the Add() method.

Firstly, declare an integer list in C# −

List<int> list1 = new List<int>();

Now add integer values −

list1.Add(900);
list1.Add(400);
list1.Add(300);

Let us see the complete code −

Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;

namespace Demo {
   public class Program {
      public static void Main(String[] args) {
         List<int> list1 = new List<int>();
         list1.Add(900);
         list1.Add(400);
         list1.Add(300);
         Console.WriteLine(list1.Count);
      }
   }
}
