Why does copy of the List still change properties in the original List using C#

Question

Lets say I have this class

public class Employee
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public bool isActive {          


        

Answer 1

The copy is a new List object, but it contains references to the same set of Employee objects that are in the original list. If you want the Employee objects in the two lists to be independent, then you have to copy them individually and put the copies into a new list.
