WebApi Newtonsoft.Json.JsonConvert.DeserializeObject <Class> Error

Question

I am doing a WebApi Method in Visual Studio 2013 and I want to Deserialize a Class Type. My Class is like this

[JsonObject]
    class JOTA
    {
        [JsonProperty("ProductId")]
        public int ProductId { get; set; }
        [JsonProperty("Name")]
        public string Name { get; set; }
    }

My call is like this.

 public void ReturnListProd(JOTA PP)
 {
 JOTA product = Newtonsoft.Json.JsonConvert.DeserializeObject<JOTA>(PP);
 }

I have a compile error

'Network.Json.Json.Converter[] has some invalid argument'

But, if a define an ArrayList

public void ReturnListProd(ArrayList PP)
{
JOTA product = Newtonsoft.Json.JsonConvert.DeserializeObject<JOTA>(PP[0].ToString());
}

I have no error. But in this case, it does not help on what I need.

What I am missing? Thanks

You don't need the attributes if the property names are not different.

public class JOTA
{
    public int ProductId { get; set; }
    public string Name { get; set; }
}

public void ReturnListProd(JOTA PP)
{
   var product = PP; //not really needed you can just use PP directly
}

You only need to deserialize if you are receiving a json string. Because you are using WebAPI I would suggest changing your API endpoint to a proper REST endpoint. Example:

[HttpPost, Route("api/products/add")]
public IHttpActionResult ReturnListProd([FromBody]JOTA PP)
{
    try
    {
        //do something with passed in data
        var name = PP.Name;

        //always at minimum return a status code
        return Ok();
    }
    catch
    {
        //returns 500
        return InternalServerError();
    }
}

Then change your ajax url from: url: "yourController/ReturnListProd" to: url: "/api/products/add"
