C#: How do you implement the command pattern?

1public interface ICommand
2{
3    void Execute();
4    void Undo();
5}
6
7public class MoveCommand : ICommand
8{
9    private readonly Editor _editor;
10    private readonly Position _delta;
11    private Position _previous;
12
13    public void Execute()
14    {
15        _previous = _editor.Position;
16        _editor.Move(_delta);
17    }
18
19    public void Undo() => _editor.Position = _previous;
20}
