Cannot access a non-static member of outer type via nested type

Question

I have error

Cannot access a non-static member of outer type \'Project.Neuro\' via nested type \'Project.Neuro.Net\'

with cod

Answer 1

Even though class is nested within another class, it is still not obvious which instance of outer class talks to which instance of inner class. I could create an instance of inner class and pass it to the another instance of outer class. Therefore, you need specific instance to call this OtherMethod().

You can pass the instance on creation:

class Neuro
{
    public class Net
    {
        private Neuro _parent;
        public Net(Neuro parent)
        {
         _parent = parent;
        }
        public void SomeMethod()
        {
            _parent.OtherMethod(); 
        }
    }

    public int OtherMethod() 
    {
        return 123;  
    }
}
