嗨
我不确定你想要得到什么，但如果你只需要你可以做的最后一个索引：
Hi Jai,
Im not sure on what you are trying to get but if you simply need the last index you could do :
combobox.Items.Count - 1
并定位于：
and to position on that :
last = combobox.items.count - 1
combobox.selectedindex = last
我希望这有帮助，

I hope this helps,

comboBox有一个MaxDropDownI tems属性（也可以在设计时或运行时设置）
例如
comboBox has a MaxDropDownItems property (which can also be set at design time or runtime)
e.g.
this.comboBox1.MaxDropDownItems = 30;
