How to Clone Objects

Question

When I do the following.. anything done to Person b modifies Person a (I thought doing this would clone Person b from Person a). I also have NO idea if changing Person a wil

Answer 1

In my opinion, the best way to do this is by implementing your own Clone() method as shown below.

class Person
{
    public string head;
    public string feet;

    // Downside: It has to be manually implemented for every class
    public Person Clone()
    {
        return new Person() { head = this.head, feet = this.feet };
    }
}

class Program
{
    public static void Main(string[] args)
    {
        Person a = new Person() { head = "bigAF", feet = "smol" };
        Person b = a.Clone();

        b.head = "notEvenThatBigTBH";

        Console.WriteLine($"{a.head}, {a.feet}");
        Console.WriteLine($"{b.head}, {b.feet}");
    }
}

Output:

bigAf, smol

notEvenThatBigTBH, smol

b is totally independent to a, due to it not being a reference, but a clone.

Hope I could help!
