Should I use ICloneable?
Should I use ICloneable?
4 Answers. 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 in c#?
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. MemberwiseClone method.
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 the method MemberwiseClone () doing?
The MemberwiseClone method creates a shallow copy by creating a new object, and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed.
How do you clone an object in C#?
The first way to clone an object is to simply implement the ICloneable interface provided by . NET. This interface has a single Clone method, inside which we should call the MemberwiseClone method of the Object class.
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.
How do you clone an object using ICloneable interface?
What is shallow copy?
A duplicate reference to a structure such as a variable, file or object. Shallow copy examples are shortcuts, symbolic references and programming pointers, all of which contain the address of and point to the data structure, but do not contain the data themselves.
Why is MemberwiseClone protected?
Performing a MemberwiseClone on an object will frequently yield a broken object; attempting using any properties or methods of the broken object may corrupt the original.
Does AutoMapper deep copy?
This applies recursively to all members, so you better make sure AutoMapper has mappings for member classes that you want to deep copy, and doesn’t have mappings for member classes that you want to shallow copy.
What is difference between copy and clone in C#?
Clone will copy the structure of a data where as Copy will copy the complete structure as well as data.
What is Python Deepcopy?
Deep copy is a process in which the copying process occurs recursively. It means first constructing a new collection object and then recursively populating it with copies of the child objects found in the original. In case of deep copy, a copy of object is copied in other object.
Is the ICloneable interface a deprecated interface?
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.
Why is ICloneable not implemented in.net framework?
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.”
Is the content class supposed to implement ICloneable?
The Content class does not implement ICloneable so this statement cannot compile. You are getting a bit lost, I can not see which implementation of Cloner you actually used and how this class has anythingto do with Person. Do note that you did not actually test whether you got a deep clone.
How to skip the first overriding step in ICloneable?
If you want to skip the first overriding step (at least in the default case), you can also suppose a default constructor signature (e.g. parameterless) and try to instantiate a clone instance using that constructor signature with reflection.
