A brief discussion on shallow copy and deep copy in .Net

Object copying is the process of copying the properties of a data object to another object of the same data type. In .Net shallow copy and deep copy are used to copy data between objects. The following article will give you a brief understanding of shallow copy and deep copy in .Net. I hope it will be helpful to you.

What is a shallow copy?

Shallow copy creates a new object and then copies the non-static fields of the current object to the new object. If the field is a value type, a bit-by-bit copy of the field is performed. If the field is a reference type, the unique reference is copied, but the referenced object itself is not copied; therefore the original and clone refer to the same object.

A shallow copy of an object is a new object whose instance variables are the same as the old object. In .Net shallow copying is done by the object method MemberwiseClone().

If you have an object with a value and you want to create a copy of the object in another variable of the same type, then you can use shallow copy and all the attribute values ​​belonging to the value type will be Copy, but if you have a property of reference type, this instance will not be copied, only the instance will be referenced.

What is a deep copy?

Deep copy is the process of creating a new object and then copying the fields of the current object to the newly created object to create a complete copy of the internal reference type. If the field is a value type, a bit-by-bit copy of the field is performed. If the field is a reference type, a new copy of the reference object is made.

#A deep copy of an object is a new object with completely new instance variables, it does not share objects with the old object. When performing Deep Copy, the class to be cloned must be marked [Serializable].

Deep copy aims to copy all elements of an object, including value type elements that are directly referenced and indirect reference elements that are reference types that contain a reference to a memory location that contains the data rather than the data itself.
