Monotouch ABAdressBook GetPhones Check For Null

ABAddressBook mybook = new ABAddressBook();
ABPerson[] allPeople =  mybook.GetPeople();
foreach(ABPerson thisPerson in allPeople){

      if(thisPerson.GetPhones() != null)
             ABMultiValue<string> myMultiPhone = thisPerson.GetPhones();

      }
}

I have the previous code in my application. With Monotouch build 1.4 my application errors out. If there is no phone number associated with a contact, I get a null error. Does anyo开发者_Python百科ne have any idea how to check for null?

I ended up putting the code in a try catch. Oh well, it works.
