For Loop Example

Description :
In this example, we are using (for loop)statement to show counting on listbox.

Ingredients:
1) One List Box
2) One Button

Programming (Ascending Order) :
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            int A;
            for (A = 1; A < 10; A++ )
            {
                listBox1.Items.Add(A);
           
            }

            int B;
            for (B = 1; B < 10; B++)
            {
                listBox1.Items.Add(B);

            }
            }
         
        }
    }

Output:
1 to 9

Programming (Decending Order):

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
         
            int B;
            for (B = 10-1; B >= 0; B--)
            {
                listBox1.Items.Add(B);

            }
            }
         
        }
    }

Output :
9 to 1
