Deep Copy in C# (Cloning for a user defined class)

原文：http://www.c-sharpcorner.com/UploadFile/sd_surajit/cloning05032007012620AM/cloning.aspx

  

Have you ever used the Clone() method of DataSet? This method creates an empty class with same structure as original DataSet.

 

You can write your own clonable classes. To do so, you must implement IClonable. The following code shows a clonable Test class.

 

using System.IO;

using System.Runtime.Serialization.Formatters.Binary;

public

{

    public Test()

    {

    }

    // deep copy in separeate memory space

    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;

    }

}
