I Want use Reflection to dynamic to populate any class, but when this class has a property as other class I have encountered problem. in this example above I reproduce, a part of code to show same dificult. I Cant convert object to Address.

Can you help me?

public class Destinatary 
{
    public string DetinataryID { get; set; }
    public string Name { get; set; }
    public Address Address { get; set; }


}

public class Address
{
    public string Place { get; set; }
    public string PostalCode { get; set; }
}


class Program
{
    static void Main(string[] args)
    {
        Destinatary destinataryTest = new Destinatary();
        Type type = typeof(Destinatary);
        destinataryTest = GenerateDataSample(destinataryTest);

        Console.WriteLine($"Name: {destinataryTest.Name}");
        Console.WriteLine($"Place: {destinataryTest.Address.PostalCode}");
        Console.WriteLine($"City: {destinataryTest.Address.City.Name}");
        Console.ReadLine();
    }

    private static T GenerateDataSample<T>(T classToWork)
    {
        Type typeToWork = typeof(T);
        object tipoInstance = Activator.CreateInstance(typeToWork);
        foreach (var classProperty in typeToWork.GetProperties())
        {

            if (classProperty.PropertyType.FullName.StartsWith("System."))
            {
                var propertyVal = RandomString(10,false ); 
                classProperty.SetValue(tipoInstance, propertyVal, null);
            }
            else
            {
                var instanceIntermediate = Activator.CreateInstance(classProperty.PropertyType);
                instanceIntermediate = GenerateDataSample(instanceIntermediate);                    
                classProperty.SetValue(tipoInstance, instanceIntermediate, null); //here there is a probleman (Cant convert Object to Address)

            }
        }

        return (T)tipoInstance;
    }

}
