Find The Mode Or Popularity Of A Number In A Group Of Numbers In .NET?

Say for instance, I gave you the numbers

1, 2, 3, 4, 4, 6, 9, 1, 3, 4, 5, 5, 2, 4, 7, 9, 1, 5, 3, 6, 6, 8, 1, 1, 4, 7, 7, 8, 2, 4, 2, 1, 9, 1, 0, 1, 6, 3, 2, 1, 8, 8, 9, 8, 1, 5, 3, 2, 3, 4, 7, 9, 0, 1, 2, 4, 7, 4, 3, 9, 7, 2, 0, 1, 6, 3, 8, 1, 2, 4

What number appears more than any other number?This is very important to me, ...I need to find the MODE, of those group of numbers, ...the way that I did it before, I would make 10 TextBoxes, and have another text box to enter the number, and when the number gets entered it would increment the value of which ever textbox the number was in the main textbox, so if I entered a 1 into the main textbox, then the zero in textbox (1), would be incremented to 1, and if another 1 was enered and the button was clicked, the 1 in the Textbox for 1, would be incremented to 2, because 1 has a popularity of 2 now and has apeared 2 times..

Here's some code, to show what I've come up with by myself.

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ONE.Text = ONE.Text + 1
End If

[code]....
