It looks like that if smb don't want do smth by him/herself and first of all go and post it on the site. Maybe there is a simpleton who will scribble the answer.
Your question it is just a nonsense.You may found how to operate with the arrays, I bet, on the first 50 pages of any book related to C#

The codes that you need are below (You should write your values inside a textbox inserting spaces between them):

C#

string[] strArray = TextBox1.Text.Split(' ');

int biggest = Int32.MinValue;
int smallest = Int32.MaxValue;

for (int i = 0; i < strArray.Length; i++)
{
    int intVal = Int32.Parse(strArray[i].Trim());

    if (intVal > biggest)
        biggest = intVal;

    if (intVal < smallest)
        smallest = intVal;
}

MessageBox.Show("The biggest: " + biggest.ToString() +
                ", The smallest: " + smallest.ToString());

My vote of 2. Doing someone's homework will certainly NOT help them learn. By all means given them concepts and such, but giving them copy/paste capable code is useless for them.

I am just trying to give the answer. I don't have to think if she will learn, this is her problem! If she want, she can learn many things from an example. We are not her teachers.
There was a question and this is the answer.
Please don't downvote the answers again for your personal obsessions!

That is where you are wrong. If we are providing solutions here on CP, we ARE teachers and should take that approach. Most CP members do not condone cut/paste solutions for clear homework questions because we do not want to work with people who will graduate without knowing anything. Don't flatter yourself with the "personal obsession" statement. When I downvote I do it on principle based on community values. It isn't personal.

OK, i'll help you, but algorithm to display the biggest and smallest values, you must to write by yourself.
Steps to do:
1) Create new windows application project
2) On the form place:
- 1x TextBox
- 3x Buttons (change the names as follow: BtnAdd, BtnClear, BtnDisplayResults)
- 1x ListBox
3) copy and paste the code below:

VB

Public Class Form1

    Dim numbers As List(Of Integer) = Nothing 'declare list of integer

    Public Sub New()

        ' This call is required by the Windows Form Designer.
        InitializeComponent()
        numbers = New List(Of Integer) 'initialize variable
        ' Add any initialization after the InitializeComponent() call.

    End Sub

    Protected Overrides Sub Finalize()
        numbers = Nothing
        MyBase.Finalize()
    End Sub

    Private Sub BtnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnAdd.Click
        Dim sText As String = String.Empty
        sText = Me.TextBox1.Text 'get text from TextBox
        numbers.Add(Integer.TryParse(sText, 0)) 'try to add parsed value
        Me.TextBox1.Text = String.Empty 'clear TextBox
        Me.TextBox1.Focus() 
        Me.ListBox1.Items.Add(sText)
    End Sub

    Private Sub BtnClear_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnClear.Click
        Me.ListBox1.Items.Clear()
        numbers.Clear()
    End Sub

    Private Sub BtnDisplayResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnDisplayResults.Click
        'here you need to write custom algorithm

    End Sub

End Class

4) Compile project

I use: ListOf(T)[^] to store numbers.
