That would be more secure than passing the entire object as a reference in a constructor I think.

interface IObjectWithFoo
{
    int Foo { get; }
}

class FooForm : Form, IObjectWithFoo
{
    public int Foo
    {
        get { return bar; }
    }
}

class Consumer : Form
{
    public Consumer(IObjectWithFoo instance)
    {
       int val = instance.Foo;
    }
}
