how to serialize object into json using c#

I tried using 

var myobject = JsonConvert.SerializeObject(Customer);

but problem is in Customer properties are like

FirstName and my service expecting json input like firstName {"firstName":"Neo"}

statement JsonConvert.SerializeObject(Customer); gives me {"FirstName":"Neo"} which is wrong.

So How can I change first letter when JsonConvert.SerializeObject happened ?

Or How to take only one parameter as input json firstname instead if using Customer object.

You should use the Json.NET attribute support to customize the naming:

public class Customer
{
    [JsonProperty("firstName")]
    public string FirstName { get; set; }
}
