.Net reflection to get nested property with custom attribute

I want to know the best way to get the prop info and value using reflection for a nested class by its custom attribute name. With below code I can get the prop info via recursion. But is there a better way or using LINQ. Note that I do not want to hard code the class type as similar to other solution

I also want to get the property value by custom attribute

e.g var propValue = ?????

 public class PlanetRoot

    {

        public void GetNeighborMoon()

        {

            Planet planet = new Planet();

            Product product = new Product();

            Neighbor neighbor = new Neighbor();

            neighbor.Moons = 10;

            neighbor.RingColor = "Red";

            product.Neighbors = new List<Neighbor>();

            product.Neighbors.Add(neighbor);

            planet.Product = product;



            //1. Get the RingColor property info of neighbor with attribute MyDBField(Name = "NeighborRing") . Is there a better way

            PropertyInfo propInfo = DoRecursiveGetProperty(planet.GetType(), "NeighborRing");



            //2. Get the RingColor property value of neighbor with attribute MyDBField(Name = "NeighborRing")

            //var propValue = GetPropertyValue(????);

        }

    }



    private static PropertyInfo DoRecursiveGetProperty(Type type, string attribName)

    {

        PropertyInfo[] pi = type.GetProperties();

        PropertyInfo returnvalue = null;

        foreach (PropertyInfo p in pi)

        {

            var dbFieldAttribute = (MyDBFieldAttribute)Attribute.GetCustomAttribute(p, typeof(MyDBFieldAttribute));

            if (dbFieldAttribute != null && attribName.ToUpper() == dbFieldAttribute.Name.ToUpper())

            {

                returnvalue = p;

                //Console.WriteLine(p.Name + " : " + (dbFieldAttribute != null && dbFieldAttribute.Name != null ? dbFieldAttribute.Name : "****"));

                break;

            }



            if (p.PropertyType.IsClass && !p.PropertyType.IsValueType && !p.PropertyType.IsPrimitive

            && p.PropertyType.FullName != "System.String")

                DoRecursiveGetProperty(p.PropertyType, attribName);



        }



        return returnvalue;



    }

    public class Planet

    {

        public string PlanetId { get; set; }

        public string Name { get; set; }

        public string Description { get; set; }

        public Product Product { get; set; }



        [MyDBField(Name="PubDate")]

        public string Publishdate { get; set; }



    }



    public class Product

    {

        public string ProductId { get; set; }

        public List<Neighbor> Neighbors { get; set; }



    }



    public class Neighbor

    {

        [MyDBField(Name = "NeighborRing")]

        public string RingColor { get; set; }

        public int Moons { get; set; }

    }



    public class MyDBFieldAttribute : System.Attribute

    {

        public string Name { get; set; }

    }
