Is it possible to change a Winforms combobox to disable typing into it?
提问by Joan Venge
So that it just allows selecting items already inside, but not allow typing/editing the text inside it?
所以它只允许选择已经在里面的项目，但不允许在里面输入/编辑文本？

After trying ShaneFulmer's answer, I noticed that the style of the drop down was changed. This was a problem for me and apparently there is no good way of changing it. (Background color doesn't actually change it.)
在尝试了 ShaneFulmer 的回答后，我注意到下拉列表的样式发生了变化。这对我来说是一个问题，显然没有改变它的好方法。（背景颜色实际上并没有改变它。）
I ended up adding a keypress handler to prevent adding text.
我最终添加了一个按键处理程序来防止添加文本。
private void myCombo_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
