RestSharp Post a JSON Object

I am trying to post the following JSON with RestSharp:

{"UserName":"UAT1206252627",
"SecurityQuestion":{
    "Id":"Q03",
    "Answer":"Business",
    "Hint":"The answer is Business"
},
}

I think that I am close, but I seem to be struggling with the SecurityQuestion (the API is throwing an error saying a parameter is missing, but it doesn't say which one)

This is the code I have so far:

var request = new RestRequest("api/register", Method.POST);
request.RequestFormat = DataFormat.Json;

request.AddParameter("UserName", "UAT1206252627");

SecurityQuestion securityQuestion = new SecurityQuestion("Q03");
request.AddParameter("SecurityQuestion", request.JsonSerializer.Serialize(securityQuestion));

IRestResponse response = client.Execute(request);

And my Security Question class looks like this:

public class SecurityQuestion
{
    public string id {get; set;}
    public string answer {get; set;}
    public string hint {get; set;}

    public SecurityQuestion(string id)
    {
         this.id = id;
         answer = "Business";
         hint = "The answer is Business";
    }
}

Can anyone tell me what I am doing wrong? Is there any other way to post the Security Question object ?

Many thanks.

It looks like the easiest way to do this is to let RestSharp handle all of the serialization. You just need to specify the RequestFormat like so. Here's what I came up with for what I'm working on. .

    public List<YourReturnType> Get(RestRequest request)
    {
        var request = new RestRequest
        {
            Resource = "YourResource",
            RequestFormat = DataFormat.Json,
            Method = Method.POST
        };
        request.AddBody(new YourRequestType());

        var response = Execute<List<YourReturnType>>(request);
        return response.Data;
    }

    public T Execute<T>(RestRequest request) where T : new()
    {
        var client = new RestClient(_baseUrl);

        var response = client.Execute<T>(request);
        return response.Data;
    }

To post raw json body string, AddBody(), or AddJsonBody() methods will not work. Use the following instead

request.AddParameter(
   "application/json",
   "{ \"username\": \"johndoe\", \"password\": \"secretpassword\" }", // <- your JSON string
   ParameterType.RequestBody);

RestSharp supported from object by AddObject method

request.AddObject(securityQuestion);

Thanks again for your help. To get this working I had to submit everything as a single parameter. This is the code I used in the end.

First I made a couple of classes called Request Object and Security Question:

public class SecurityQuestion
{
    public string Id { get; set; }
    public string Answer { get; set; }
    public string Hint { get; set; }
}

public class RequestObject
{
    public string UserName { get; set; }
    public SecurityQuestion SecurityQuestion { get; set; }
}

Then I just added it as a single parameter, and serialized it to JSON before posting it, like so:

var yourobject = new RequestObject
            {
                UserName = "UAT1206252627",
                SecurityQuestion = new SecurityQuestion
                {
                    Id = "Q03",
                    Answer = "Business",
                    Hint = "The answer is Business"
                },
            };
var json = request.JsonSerializer.Serialize(yourobject);

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

IRestResponse response = client.Execute(request);

and it worked !

You need to specify the content-type in the header:

request.AddHeader("Content-type", "application/json");

Also AddParameter adds to POST or URL querystring based on Method

I think you need to add it to the body like this:

request.AddJsonBody(
    new 
    {
      UserName = "UAT1206252627", 
      SecurityQuestion = securityQuestion
    }); // AddJsonBody serializes the object automatically
