谁能知道如何在 VB.NET 中制作只读的 DateTime 选择器？

There is no built-in way to change the DateTimePickercontrol to read-only. You could probably create your own custom read-only control that either contains or inherits the DateTimePickercontrol, however, you have several other much simpler options:
没有将DateTimePicker控件更改为只读的内置方法。您可能可以创建自己的自定义只读控件来包含或继承该DateTimePicker控件，但是，您还有其他几个更简单的选项：
- If you never need the value to be editable, and it is only ever read-only, then don't use the
DateTimePickercontrol. You should, instead, use aLabelcontrol. - If it's sometimes editable and sometimes read-only, use the
DateTimePickercontrol and just toggle theEnabledproperty to switch it between editable and read-only modes. - If you want it to look like other entry controls, but not be grayed-out (as is the case when you disable it), then use a
TextBoxcontrol and set it'sReadOnlyproperty toTrue.
- 如果您从不需要该值是可编辑的，并且它只是只读的，则不要使用该
DateTimePicker控件。相反，您应该使用Label控件。 - 如果它有时是可编辑的，有时是只读的，请使用
DateTimePicker控件并切换该Enabled属性以在可编辑和只读模式之间切换。 - 如果您希望它看起来像其他条目控件，但不会变灰（就像禁用它时的情况），则使用
TextBox控件并将其ReadOnly属性设置为True.
