how to get all primitive type of an object

Question

I wanna have all properties of an object which have primitive type, and if the object has a relation to another class , I wanna have the primitive properties of this another

Answer 1

I would made as follows:

    void Traverse(Type type, ISet marks, ICollection result)
    {
        if (marks.Contains(type)) return; else marks.Add(type);
        foreach (var propertyInfo in type.GetProperties())
            if (propertyInfo.PropertyType.IsPrimitive) result.Add(propertyInfo);
            else Traverse(propertyInfo.PropertyType, marks, result);
    }

and

var props = new List();
Traverse(yourRootType, new HashSet(), props);
