Answer 1

If you are using @html helper for properties then form.serialize() method will bind all the properties otherwise if you are using html elements like <input> the assign their name property same as model property.

<input type="text" name="Contact.FirstName" value="@Model.Contact.FirstName"/>

You need for format your string to proper json -

Say if you model is -

public class ContactModel
{
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }
}

public class PersonModel
{
    public ContactModel Contact { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Profession { get; set; }
}

Then you AJAX Post should be like this -

<script>
    $(function () {
        $('#click1').click(function (e) {

            var studentData = {
                "FirstName": "Rami",
                "LastName": "Vemula" ,
                "Contact": { "City": "Hyd"}
            };

            $.ajax({
                url: "@Url.Action("Submit")",
                type: "POST",
                data: JSON.stringify(studentData),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

Then output is going to be -

Create a instance of ContactModel and assign it to contact under PersonModel after creating instance of PersonModel. Please let me know in case of any clarification needed
