Как использовать icloneable интерфейс в C#

---

Hey, I'm attempting to clone an object. The Update Student Scores form should create a clone of the current student object and then apply changes to the clone. That way the changes will be saved to the current student only if the user clicks the OK button. To create a clone, the Student class will need to implement the ICloneable interface, and the Clone method will need to implement a deep copy. So far, I've learned that you want a deep copy of something when you need a copy of the other objects contained by the original (rather than pointers to the location of those objects in the original), so that when you make changes to these copied properties, you don't affect the original object. What I'm struggling with though is applying it to my model. Below is the student class I'm trying to clone and the update student form. I've also attached the source code if that helps. Thanks!

Что я уже пробовал:

Я пытался клонировать класс, но не знаю, как применить изменения только к клону, чтобы таким образом изменения были сохранены для текущего ученика только в том случае, если пользователь нажмет кнопку ОК
