RestSharp POST Object as JSON

Here is my class:

public class PTList
{
    private String name;

    public PTList() { }
    public PTList(String name)
    {
        this.name = name;
    }


    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }

}

and my RestSharp POST Request:

    protected static IRestResponse httpPost(String Uri, Object Data)
    {
        var client = new RestClient(baseURL);
        client.AddDefaultHeader("X-Authentication", AuthenticationManager.getAuthentication());
        client.AddDefaultHeader("Content-type", "application/json");
        var request = new RestRequest(Uri, Method.POST);

        request.RequestFormat = DataFormat.Json;

        request.AddJsonBody(Data);

        var response = client.Execute(request);
        return response;
    }

and when I use the httpPost method with the good URI and a PTList object, the front API anwser that "name" is null. I think that my PTList object is not serialized as a valid JSON in the request for the API, but can't understand what's going wrong.

Json serializer used by RestSharp by default does not serialize private fields. So you can change your class like this:

public class PTList
{        
    public PTList() { }

    public PTList(String name) {
        this.name = name;
    }

    public string name { get; set; }
}

And it will work fine.

If capabilities of default serializer will be not enough (as far as I know - you cannot even rename properties with it, to make Name serialize as name for example) - you can use better serializer, like JSON.NET, like described here for example.

There are a couple of issues I can see.

The first is that the object you're sending has no public fields, I'd also simplify the definition a little too:

public class PTList
{
    public PTList() { get; set; }
}

The second issue is that you're setting the Content-Type header which RestSharp will do by setting request.RequestFormat = DataFormat.Json

I'd also be tempted to use generics rather than an Object

Your httpPost method would then become:

protected static IRestResponse httpPost<TBody>(String Uri, TBody Data)
    where TBody : class, new
{
    var client = new RestClient(baseURL);
    client.AddDefaultHeader("X-Authentication", AuthenticationManager.getAuthentication());
    var request = new RestRequest(Uri, Method.POST);
    request.RequestFormat = DataFormat.Json;
    request.AddJsonBody(Data);

    var response = client.Execute(request);
    return response;
}

You could try this instead of AddJsonBody:

request.AddParameter("application/json; charset=utf-8", JsonConvert.SerializeObject(Data), ParameterType.RequestBody);

It's one of the solutions here: How to add json to RestSharp POST request
