c# 深复制

实现深复制的思路为：先将类序列化到内存中，然后从内存中反序列化回来，就可实现深复制。

有类：

[Serializable]

        class Product

        {

            public string Name { get; set; }

            public int CategoryID { get; set; }

        }

序列化代码：

using System.IO;

using System.Runtime.Serialization.Formatters.Binary;

Product p1 = new Product() { Name = "", CategoryID = 1 };

MemoryStream stream = new MemoryStream();

BinaryFormatter formatter = new BinaryFormatter();

formatter.Serialize(stream, p1);

stream.Position = 0;

Product p = new Product();

p= formatter.Deserialize(stream) as Product;
