我需要在1个组合框中选择项目，将在另一个组合框中显示此选项中的待定项目。我不在项目中使用SQL，EXEL，ACCESS或VBA。我在winforms中添加了自己的项目。它看起来应该像这样：http：//imgur.com/BYQNVzd非常感谢你的帮助。

Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
    If ComboBox1.SelectedIndex = 0 Then
        ' Index 0 is BMW
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"X5", "X6", "7-series", "5-series", "3-series"})
    ElseIf ComboBox1.SelectedIndex = 1 Then
        ' Toyota
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"Teana", "Camry"})
    ElseIf ComboBox1.SelectedIndex = 2 Then
        ' kia
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"Rio"})
