如何listbox在点击的同时选择前三项

先将listview的selectionmode设为multisimple
然后:
Private Sub ListBox1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.Click
        Me.ListBox1.SelectedItem = Me.ListBox1.Items(0)
        Me.ListBox1.SelectedItem = Me.ListBox1.Items(1)
        Me.ListBox1.SelectedItem = Me.ListBox1.Items(2)
    End Sub

好的
