推荐答案

ComboBox 不支持此功能.确切的原因在时间的迷雾中迷失了，ComboBox 自 90 年代初就已经存在，但肯定与让文本框部分中的文本与下拉文本中的文本对齐的尴尬有关.用DrawItem自定义绘图也解决不了，只会影响下拉项的外观.

This isn't supported for ComboBox. The exact reasons are lost in the fog of time, ComboBox has been around since the early nineties, but surely has something to do with the awkwardness of getting the text in the textbox portion to line up with the text in the dropdown. Custom drawing with DrawItem cannot solve it either, that only affects the appearance of the dropdown items.

作为一种可能的解决方法，您也许可以做一些奇怪的事情，例如用空格填充项目字符串，使它们看起来居中.您需要使用 TextRenderer.MeasureText() 来确定要为每个项目添加多少个空格.

As a possible workaround, you could perhaps do something outlandish like padding the item strings with spaces so they look centered. You'll need TextRenderer.MeasureText() to figure out how many spaces to add for each item.

您所说的边框"不是边框，而是焦点矩形.您也无法摆脱它，Windows 拒绝让您创建一个不会显示带有焦点的控件的 UI.喜欢键盘而不是鼠标的用户关心这一点.没有解决方法.

The "border" you are talking about is not a border, it is the focus rectangle. You can't get rid of that either, Windows refuses to let you create a UI that won't show the control with the focus. Users that prefer the keyboard over the mouse care about that. No workaround for that one.
