Public object to be used in Form.

Question

Hello, I got question about an assignment that I've been working on for weeks.

Teacher handed back to me, and said m_contactRegistry should not be public.

How will I fix this?

 

ContactManager class with m_contactRegistry: 

 

class ContactManager

{

     public List<Contact> m_contactRegistry; //declare object of the collection

     public ContactManager()

     {

           m_contactRegistry = new List<Contact>();

     }

/// <summary>

/// returns the count of m_contactRegistry

/// </summary>

/// <param name="index"></param>

/// <returns></returns>

     public Contact GetContact(int index)

     {

           if (index < 0 || index >= m_contactRegistry.Count)

           return null;

           return m_contactRegistry[index];

     }

 

 

Form.cs: 

 

private void dltButton_Click(object sender, EventArgs e)

{

     string currContact;

     try { currContact = listBox.SelectedItem.ToString(); }

     catch (Exception) { return; }

     foreach (ContactFiles.Contact c in m_contactMngr.m_contactRegistry)

     {

          if (c.ToString() == currContact)

          {

               m_contactMngr.m_contactRegistry.Remove(c);

               break;

           }

        }

 

 

 

 

Thank you
