Is there a way to select items in a listbox without having to loop through the whole list?

     
      For Each item As ListItem In lstBxBrand.Items
            If item.Text = "Dell" Or item.Text = "HP" Or item.Text = "Sony" Then
                item.Selected = True
            End If
        Next


Thank you.

Public Shared Sub SetSelected(ByVal objControl As ListBox, ByVal val As String)
        Dim oDR As DataRowView
        Dim i As Integer
        For i = 0 To objControl.Items.Count - 1
            If (objControl.Items(i).Value = "Dell") Or (objControl.Items(i).Value = "HP") Or (objControl.Items(i).Value = "Sony") Then
                objControl.Items(i).Selected = True
            End If
        Next
    End Sub

ListItem li = ListBox1.Items.FindByText("Dell"); // also FindByValue
li.Selected = true;
or
ListBox1.Items[5].Selected = true;
or
ListBox1.SelectedIndex = 5;
