Question

I am doing exercises in Head First C# book.

This code is supposed to be about encapsulation.

class DinnerParty
{
    private int NumberOfPeople;
         ....

    public void SetPartyOptions(int people, bool fancy) {
        NumberOfPeople = people;
        .....
    }

    public int GetNumberOfPeople() {
        return NumberOfPeople;
    }
}

In form1 class

public partial class Form1 : Form
{
    DinnerParty dinnerParty;
    public Form1()
    {
        InitializeComponent();

        dinnerParty = new DinnerParty() {NumberOfPeople = 5 };

        ...

Is this suppose to work?

Visual Studio is showing me an error. (cannot access due to its protection level)

I am very new at this.

Thanks

No that is not supposed to work. I can’t see the book, so I can’t comment on the context. However:

public int NumberOfPeopoe {get;set;} 

Is a reasonable fix.
