Deep Copy of a C# Object

Question

I am working on some code that is written in C#. In this app, I have a custom collection defined as follows:

public class ResultList : IEnumerable&l         


        

Answer 1

The approach involving the least coding effort is that of serializing and deserializing through a BinaryFormatter.

You could define the following extension method (taken from Kilhoffer’s answer):

public static T DeepClone(T obj)
{
    using (var ms = new MemoryStream())
    {
        var formatter = new BinaryFormatter();
        formatter.Serialize(ms, obj);
        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}

…and then just call:

ResultList clone = DeepClone(original);
