Câu trả lời

The concepts of shallow copy and deep copy in C# refer to different ways of creating copies of objects. Here's an explanation of each:

Shallow Copy:

  • A shallow copy creates a new object that has a copy of the references to the same elements as the original object[1][2].
  • It copies the value type fields bit-by-bit and reference type fields as references[2].
  • Modifications to the copied object's reference types will affect the original object, as both objects point to the same memory location[1][3].
  • Shallow copying is faster and more memory-efficient than deep copying[1].

Example:

ShallowCopy obj = new ShallowCopy();
ShallowCopy objClone = (ShallowCopy)obj.MemberwiseClone(); // Shallow copy

Deep Copy:

  • A deep copy creates a new object with copies of all the values of the original object[1][3].
  • It recursively copies the object's fields, creating new instances of reference type fields[1][4].
  • The new object is completely independent of the original object[...
