Task 1- Add a search facility (button) to find a value in the array using a sequential search and display the details to the user.
Task 2- Add a search facility (button) to find a value in the array using a binary search and display the details to the user.

How do I apply the search facilities for both sequential and binary searches?

What I have tried:

C#

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 WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        Int32[] numbers = new Int32[1000];

        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        private void button1_Click_1(object sender, EventArgs e)
        {
            Int32 x = 0;
            while (x < numbers.Length)
            {
                numbers[x] = x;
                x = x + 1;
            }

            lbxOutput.Items.Clear();
            for (Int32 i = 0; i < numbers.Length; i++)
            {
                lbxOutput.Items.Add(numbers[i]);
            }
        }
    }
}

The requirement is extremely simple.
How is it possible that you get nothing ?

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.

As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
