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 m_contactRegistry; //declare object of the collection public ContactManager() { m_contactRegistry = new List (); } /// /// returns the count of m_contactRegistry /// /// /// public Contact GetContact( int index) { if (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

public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender EventArgs e) { ContactManager mngr = new ContactManager(); string currContact; try { currContact = listBox.SelectedItem.ToString(); bool flg = mngr.RemoveCondact(currContact); if (flg ) MessageBox.Show(Successfully Removed); } catch (Exception) { return; } } } class ContactManager { private List m_contactRegistry; //declare object of the collection public ContactManager() { m_contactRegistry = new List (); } /// /// returns the count of m_contactRegistry /// /// /// public Contact GetContact(int index) { if (index = m_contactRegistry.Count) return null; return m_contactRegistry[index]; } public bool RemoveCondact(string str) { foreach (Contact c in m_contactRegistry) { if (c.ToString() == str) { m_contactRegistry.Remove(c); return true; } } return false; } } public class Contact { }
