Object Shallow Copy in C#

Question

I know to perform a shallow copy in C# we could use MemberwiseClone() function but I have an object inside a function and I want to take a copy of this object, so when I added to a list it won't refer to the same object when the object is changed here is my code

public void Do(object undoState)
    {
        _index += 1;
        if (_buffer.Count > _index)
            _buffer.RemoveRange(_index, _buffer.Count - _index);
        _buffer.Add(undoState);
    }

I want to copy the UndoState object to a new object and added to the buffer

thank you

Answer 1

implement the ICloneable interface, and add your copy logic into it. Now instead of receiving an object in your Do method, use ICloneable.
