Parse whois answer

I want to create whois class like that

public class DomainInfo{     public string NameServer {get;set;}             public string CreationDate {get;set;}     public string UpdatedDate {get;set;}      public string ExpirationDate {get;set;}     public string Status {get;set;}             public string RegistrantName {get;set;}     public string RegistrantOrganization {get;set;}     public string Registrantemail {get;set;}             public static DomainInfo Parse(string inputData)  {     ......  }}

But I have some problems because different DNS servers return different answers and it's a very difficult task to parse returned answers. How can this be done?
