Hi Richard,

I'm not sure what exactly your question is... Do you want to pass a set of ten textboxes to a method? That's possible with code like this:

private void button1_Click(object sender, EventArgs e)
{
  ProcessTextboxes(new TextBox[] {txtCity,txtName} );
}

public void ProcessTextboxes(TextBox[] textboxes)
{
  foreach (TextBox txt in textboxes)
  {
    txt.BackColor = Color.Azure;
  }
}
