推荐答案

设置ComboBox的MaxLength属性，它们不能输入太多数据. ..

Set the MaxLength property of the ComboBox and they can''t enter too much data...

OriginalGriff 给出的解决方案1很好. 但是，如果需要允许项目的宽度大于ComboBox的宽度，那么我认为ComboBox 组件中没有内置功能来显示工具提示.因此，作为替代方案，可以使用派生组件，并且以下Code Project文章
带有32位工具提示的Windows.Forms.ComboBox Windows XP(SP2) [带有超级"项目提示的Windows.Forms.ComboBox适用于32位Windows XP(SP2) [ ^ ]
可能会有所帮助.

The Solution 1 given by OriginalGriff is very good.
But, in case if it required to allow width of items more than the width of the ComboBox, then I think there is no built in feature in ComboBox component to show the tool tips. So, as an alternative a derived component may be used and the following Code Project articles
A Windows.Forms.ComboBox with Item ToolTips for 32 bit Windows XP (SP2)[^]
A Windows.Forms.ComboBox with Item ''Super'' ToolTips for 32 bit Windows XP (SP2)[^]
may be helpful.
