Cast an object into an object from a derived class

Question

I have a class Record that works fine:

public class Record 
{
    protected string table;
    protected string idcolumn;
    public Record(string _t         


        

Answer 1

As I said in comments

You can cast a Dog to Animal but not Animal to Dog(unless that animal is Dog). More clearer All Dogs are Animal but not all Animals are Dogs

Record record = new Record();
Order order = (Order)record;//wont work since record is some record not an Order

To make it work you've to do something like this

Record record = new Order();

Then you can cast it like this

Order order = (Order)record;//works since record is Order
