Display all properties and if property is a class display its properties

I am using reflection to loop through classes of a DLL and display the properties of that class; but there are cases where the property is another class, and I need to loop through that property's properties and display them.

What I currently have will only display the properties, and not sub properties:

treeView1.Nodes.Clear();

Assembly assembly = Assembly.LoadFrom(@"Path\Domain.dll");

            int count = 0;
            foreach (Type type in assembly.GetTypes().Where(t => t.IsClass))
            {               
                var node = treeView1.Nodes.Add(type.FullName);

                var x = ((System.Reflection.TypeInfo)((assembly.GetTypes()))[count]).DeclaredProperties;

                x.ToList().ForEach(item => treeView1.Nodes[count].Nodes.Add(item.Name));

                count++;                
            }           
        }

Any help to display sub properties
