What is the use of IClonable interface in .NET?

Question

I just wanted to know what is the use of IClonable interface in .NET?

Answer 1

What about defining IShallowClone and IDeepClone like this?

public interface IShallowClone { T ShallowClone(); }
public interface IDeepClone { T DeepClone(); }

public interface IA : IShallowClone, IDeepClone { double a { get; } IA ia { get; } }
public interface IB : IA, IShallowClone, IDeepClone { double b { get; } IB ib { get; } }

public class A : IA
{
    public double a { get; private set; } 
    public IA ia { get; private set; }
    public A(IA that) { this.a = that.a; this.ia = (ia as IDeepClone).DeepClone(); } 
    public IA DeepClone() { return new A(this); }
    public IA ShallowClone() { return this.MemberwiseClone() as IA; }
}
public class B : A, IB 
{ public double b { get; private set; } 
    public IB ib { get; private set; }
    public B(IB that) : base(that) { this.b = that.b; this.ib = (ib as IDeepClone).DeepClone(); } 
    public new IB DeepClone() { return new B(this); }
    public new IB ShallowClone() { return this.MemberwiseClone() as IB; }
}
