@DavidG - I've now had a chance to play with Newtonsoft JSON.Net. I have one complaint... why didn't you tell me about it earlier?! ;-) — freefaller

Use Json.Net library, you can download it from Nuget. Try this

var contactCollection = new Contacts
{
    phoneMobiles = new List<PhoneMobile>
    {
        new PhoneMobile { phoneMobile = "8103267511" }
    },
    phoneLandlines = new List<PhoneLandline>()
    {
        new PhoneLandline { phoneLandLineNumber = "8103267511" }
    },
    emails = new List<Email>()
    {
        new Email { email = "[email protected]" }
    }
};

var jsonString = Newtonsoft.Json.JsonConvert.SerializeObject(contacts);

It will serialize object to json except contactPerson section

If you need serialize object with root name contacts then try

var collectionWrapper = new {
    contacts = contactCollection
};

var jsonString = Newtonsoft.Json.JsonConvert.SerializeObject(collectionWrapper);

then the result will be like:

{"contacts":{"phoneMobiles":[{"phoneMobile":"8103267511"}], "phoneLandlines":[{"phoneLandLineNumber":"8103267511"}], "emails":[{"email":"[email protected]"}]}}
