Should I use ICloneable?
You shouldn’t. Microsoft recommends against implementing ICloneable because there’s no clear indication from the interface whether your Clone method performs a “deep” or “shallow” clone.
What is ICloneable?
The ICloneable interface enables you to provide a customized implementation that creates a copy of an existing object. The ICloneable interface contains one member, the Clone method, which is intended to provide cloning support beyond that supplied by Object.
What is C# MemberwiseClone?
MemberwiseClone Method is used to create a shallow copy or make clone of the current Object. Shallow copy is a bit-wise copy of an object. In this case, a new object is created and that object has an exact copy of the existing object.
How do you clone an object in C#?
copy link The solution
- Option 1: Serialize and deserialize the object via an extension method.
- Option 2: Implement the ICloneable interface.
- Option 3: Implement an explicit DeepCopy interface.
- Option 4: Use a copy constructor.
- A future option: Records.
Which of the following method should be implemented when ICloneable interface is used?
ICloneable interface) should contain public or protected copy constructor. Base class should declare Clone method as virtual. Derived class should contain copy constructor which calls base class’s copy constructor. Both base and derived class should implement Clone method by simply invoking the copy constructor.
What is deep copy vs shallow copy C#?
While in shallow copy the members of the copied object refer to the same object as the original object, in a deep copy, separate instances of each of the reference type members in the original instance is created in the new or cloned instance.
Why clone method is protected?
clone() method is protected i.e. accessed by subclasses only. Since object is the parent class of all sub classes, so Clone() method can be used by all classes infact if we don’t have above check of ‘instance of Cloneable’.
What is shallow and deep copy?
A shallow copy constructs a new compound object and then (to the extent possible) inserts references into it to the objects found in the original. A deep copy constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original.
What is drawback of shallow copy?
The problem with the shallow copy is that the two objects are not independent. If you modify the one object, the change will be reflected in the other object. A deep copy is a fully independent copy of an object. If we copied our object, we would copy the entire object structure.
What are the differences between a shallow copy and a deep copy?
In Shallow copy, a copy of the original object is stored and only the reference address is finally copied. In Deep copy, the copy of the original object and the repetitive copies both are stored.
Is copy disk same as clone?
It’s possible to clone a disk by using a disk image, but the two are distinctly different in the process they use to copy hard drives. Disk cloning creates a functional one-to-one copy of a hard drive, while disk imaging creates an archive of a hard drive that can be used to make a one-to-one copy.
Is cloning same as copying?
clone – create something new based on something that exists. copying – copy from something that exists to something else (that also already exists).
How does clone method work?
clone() method acts like a copy constructor. It creates and returns a copy of the object. Since the Object class has the clone method (protected) you cannot use it in all your classes. The class which you want to be cloned should implement clone method and overwrite it.
Why clone and finalize () is protected in object class?
this is because the clone method of Object class cannot create clone of an object on its own. You need to deep copy the fields in your class that are references. If you relied on the clone method of the Object class then the obj would not be cloned…
Where is shallow copy used?
Your Answer
- Asking for help, clarification, or responding to other answers.
- Making statements based on opinion; back them up with references or personal experience.
Should I use AutoMapper?
If you have to do complex mapping behavior, it might be better to avoid using AutoMapper for that scenario. Reverse mapping can get very complicated very quickly, and unless it’s very simple, you can have business logic showing up in mapping configuration.
Why should I not use the ICloneable interface?
If you use this interface you will get beat up by the style police because the .NET Framework Design Guidelines say not to implement it because, to quote the guidelines, “when using an object that implements a type with ICloneable, you never know what you are going to get. This makes the interface useless.”
How to implement ICloneable in a class with a twist?
Implement ICloneable in a class with a twist. Expose a public type safe Clone () and implement object Clone () privately.
Is the book on ICloneable worth it?
Frankly, the book isn’t teaching you very good practices. The ICloneable interface narrowly escaped being deprecated and should be avoided. It is a broken interface, it doesn’t allow the caller to specify whether a deep or a shallow copy is desired.
Is object cloning in the CLR type safe?
The CLR requires a method definition object Clone () which is not type safe. It is common practice to override this behavior and define a type safe method that returns a copy of the containing class. It is up to the author to decide if cloning means only shallow copy, or deep copy.
