Get all properties of a model that are not a number [duplicate]

This question already has an answer here:

• Using .Net, how can I determine if a type is a Numeric ValueType? 7 answers

Assuming I have a model like this (I shortened it a bit):

class NewsletterDatum
{
    public string FullName{ get; set; }
    public string Email { get; set; }
    public string OptOutLink { get; set; }
    public long ConciergeId { get; set; }
    public long AwardCount { get; set; }
    public int YearsMember {get; set; }
    public string CardNumber { get; set; }
    public string MemberName { get; set; }
    public string PointBalance { get; set; }
    public List<string> StoredKeyWords { get; set; }
    public List<string> FriendIds { get; set; }
}

I want to get the list of properties of this model that are not numerical, is there a way of doing this without comparing types with int, long, decimal, etc..?
