通过将datetimepicker格式设置为自定义"，并将CustomFormat设置为空白空间"，我们可以将datetimepicker字段保留为空白.这会将datetimepicker字段显示为null，但该值不会更改为null.锥在您的代码中进行处理.


dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat ="; //带有一个空格的字符串

We can keep datetimepicker field as blank by setting datetimepicker Format to "Custom" and CustomFormat to "blank space". This will display the datetimepicker field as null but the value doesnt change to null.That cone be handle in ur code.


dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat =""; //a string with one whitespace
