在C#中克隆列表<List <T >>的正确方法

Question

我正在努力克隆一个引用类型的列表列表.我尝试ICloneable在我的引用类中实现,但是,它似乎没有调用Clone()它中的方法.

码:

public class Solid : ICloneable{

    private double[,] _points;  //vertices do solido
    private int[,] _edges;  //arestas do solido
    public int[,] Faces { get; private set; }   //faces do solido

    public int[,] Edges {
        get { return _edges; }
        set { _edges = value; }

    }
    ...

    public object Clone() {
        MemoryStream ms = new MemoryStream();
        BinaryFormatter bf = new BinaryFormatter();

        bf.Serialize(ms, this);

        ms.Position = 0;
        object obj = bf.Deserialize(ms);
        ms.Close();
        return obj;
    }
}

使用LINQ,您可以执行以下操作:

public List<List<T>> Clone<T>(List<List<T>> original) where T : ICloneable
{
    return original
        .Select(sl => sl.Select(x => (T)x.Clone()).ToList())
        .ToList();
}
