How do you perform deep cloning or deep copying of a collection in C#?

• Deep cloning copies the collection and all objects inside it recursively.
• Ways to deep clone:
• Implement ICloneable in your objects with deep clone logic.
• Use serialization (binary, XML, JSON) to serialize and deserialize objects.
• Manually create new instances of each item.

Example (manual):

List<MyClass> DeepClone(List<MyClass> original)

return original.Select(item => item.Clone()).ToList();

Note: MyClass must implement a Clone() method that performs deep copy.
