asp.net - How to map JSON to C# Objects

Question

I am having issues with understanding how to make this happen.

Basically we have an API, the user sends a JSON of the format: (excuse the code if not perfect but you understand)

{"Profile": [{
    "Name":"Joe",
    "Last :"Doe",
    "Client":
    {
        "ClientId":"1",
        "Product":"Apple",
        "Message":"Peter likes apples"
    },
    "Date":"2012-02-14",
}]}

Ok I'm not sure if I got that JSON formatted correctly but now here is my issue.

I have a class called Profile with parameters Name, Last, and an object as one of its members called Client as well as property Date.

Something like this:

public class Profile
  {
     public string Name {get; set;}
     public string Last {get; set;}
     public Client client {get; set;}
     public DateTime dDate {get; set;}   
  }

So basically, I am not sure how to grab the JSON and then map it to my object.

Any help with "helping" me understand would be much appreciated.

You can use Json.NET to deserialize your json string as (with some modifications to your classes)

var yourObject =  JsonConvert.DeserializeObject<Root>(jsonstring);


public class Root
{
    public Profile[] Profile;
}

public class Profile
{
    public string Name { get; set; }
    public string Last { get; set; }
    public Client Client { get; set; }
    public DateTime Date { get; set; }
}

public class Client
{
    public int ClientId;
    public string Product;
    public string Message;
}
