In this example, we’ll learn how to fill a listbox with random int numbers using the C # Windows Form Application.
We will create 10 random numbers and we will list these numbers in the listbox.

Source Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 | using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace generate_random_number { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { this.Text = "csharp-console-examples.com"; this.BackColor = Color.Orange; } private void button1_Click(object sender, EventArgs e) { listBox1.Items.Clear(); Random rnd = new Random(); for(int i=1;i<=10;i++) { listBox1.Items.Add(rnd.Next(1, 100)); } } } } |
