Question

Suppose this:

class BaseClass
{
    public string MyProperty { get; set; }
    public NestedClass_ NestedClass;
    internal class NestedClass_ : BaseClass
    {
        public string MyNestedProperty { get; set; }
    }
}

Now, let’s say this:

var baseClass = new BaseClass();
baseClass.NestedClass.MyNestedProperty = "Value applied from nested class";

Can something be done to apply the same value to baseClass.MyProperty when changing baseClass.NestedClass.MyNestedProperty?

And what about the oposite case:

var baseClass = new BaseClass();
baseClass.MyProperty = "Value applied from base class";

Can something be done to apply the same value to baseClass.NestedClass.MyNestedProperty when changing baseClass.MyProperty?

Found a way…

class BaseClass
{
    private string _myProperty;

    public string MyProperty
    {
        get { return _myProperty; }
        set
        {
            _nestedClass.MyNestedProperty = value;
            _myProperty = value;
        }
    }

    private NestedClass_ _nestedClass = new NestedClass_();

    private class NestedClass_
    {
        public string MyNestedProperty { get; set; }
    }

    public string MyNestedProperty
    {
        get { return _nestedClass.MyNestedProperty; }
        set
        {
            MyProperty = value;
            _nestedClass.MyNestedProperty = value;
        }
    }
}
