cast the Parent object to Child object in C#

Question

Hi i want to cast the Parent object to Child object in C#

public class Parent
{
    public string FirstName {get; set;}
    public string LastName {get; set;         


        

Answer 1

var lstChild = lstParent.Cast().ToList();

or

var lstChild = lstParent.ConvertAll(x=>(Child)x);

Both of these, however, assume that the Parent list actually contains Child instances. You can't change the actual type of an object.
