推荐答案

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;
