Deserialize Json to class

If I have a JSON file 

{
     "firstName": "John",
     "lastName": "Smith",
     "age": 25,
     "address":
     {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": "10021"
     },
     "phoneNumber":
     [
         {
           "type": "home",
           "number": "212 555-1234"
         },
         {
           "type": "fax",
           "number": "646 555-4567"
         }
     ]
 }

, I want to use the serializer. I understand that I need to create a class that fits the JSON categories.

So I created this: 

class Person
{

    public String firstName;
    public String lastName;
    public String age;
    public class address
    {
        public String streetAddress;
        public String city;
        public String state;
        public String postalCode;
    }
    public class phoneNumber
    {
        public String type;
        public String number;
    }

}

It works fine with age and name but not with address and phoneNumber(I din't know how to creat them in the class file). I hope you can help me.

Use getters and setters

public class Person
{
public string firstName { get; set; }
public string lastName { get; set; }
public int age { get; set; }
public Address address { get; set; }
}
public class Address
{
public string streetAddress { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postalCode { get; set; }
}
public class PhoneNumber
{
public string type { get; set; }
public string number { get; set; }
}

You didn't create properties for the address and phone number. There has to be a target property in order to put data into that property.

Something like this:

class Person
{
    public string firstName { get; set; }
    public string lastName { get; set; }
    public int age { get; set; }
    public Address address { get; set; } // here
    public IEnumerable<PhoneNumber> phoneNumber { get; set; } // and here

    public class Address { /.../ }
    public class PhoneNumber { /.../ }
}
