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);
}
}
}
