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 you create is just a copy of the list. Not a copy of the objects. In other words, Employees[0] == EmployeesCopy[0].
