WebAPI Selfhost: Can't bind multiple parameters to the request's content

Question

The below code are simplified to show the necessity. May I know what is wrong? I can\'t seems to retrieve two Parameters (A and B in this case) using the [FromBody] attribut

Answer 1

Web Api doesn't support multiple [FromBody] params I think. But you can use Api model, to passing more parameters to your api action.:

public class YourApiModel
{
    public int A{ get; set; }

    public int B { get; set; }

    //...other properties    
}

After that, you can simply use this in your API controller Test:

    // POST: api/test
    public IHttpActionResult Post([FromBody] YourApiModel model)
    {
        //do something
    }

Hope it help.

Answer 2

Try the Web API code:

[DataContract]
public class Model
{
    [DataMember]
    public int A { get; set; }

    [DataMember]
    public int B { get; set; }
}

[Route("API/Test"), HttpPost]
public IHttpActionResult Test([FromUri] Model model)
