Dynamically change button background color in vb.net

Question

I have 3 buttons in my .Net app and I would like to know how I can perform the below code dynamically.

Public Class frmTC

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Button1.BackColor = Color.Red
    Button2.BackColor = Color.Yellow
    Button3.BackColor = Color.Yellow
End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    Button1.BackColor = Color.Yellow
    Button2.BackColor = Color.Red
    Button3.BackColor = Color.Yellow
End Sub

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
    Button1.BackColor = Color.Yellow
    Button2.BackColor = Color.Yellow
    Button3.BackColor = Color.Red
End Sub

End Class

Answer 1

Private Sub Button_Click(sender As Object, e As EventArgs) Handles Button3.Click
   Dim btn As Button = CType(sender, Button)
   SetColor(btn)
End Sub

Private Sub SetColor(Button button)
    Button1.BackColor = Color.Yellow
    Button2.BackColor = Color.Yellow
    Button3.BackColor = Color.Yellow
    button.BackColor =Color.Red
End Sub
