How should I use properties when dealing with read-only List members

Question

When I want to make a value type read-only outside of my class I do this:

public class myClassInt
{
    private int m_i;
    public int i {
        get { ret         


        

Answer 1

public class MyClassList
{
    private List _lst = new List() { 1, 2, 3 };

    public IEnumerable ListEnumerator
    {
        get { return _lst.AsReadOnly(); }
    }

}

To check it

    MyClassList  myClassList = new MyClassList();
    var lst= (IList)myClassList.ListEnumerator  ;
    lst.Add(4); //At this point ypu will get exception Collection is read-only.
