I have this model for an MVC WEB API controller. What will be the corresponding JSON to match this model structure?

namespace CarEvaluator.Models { [DataContract] public class Record { [DataMember] public List<Boolean> CHits { get; set; } [DataMember] public List<Boolean> MHits { get; set; } } } public void Post(Record record) { }

Structure:

{"CHits":[true,false],"MHits":[true,false]} 

Example:

var postObject = new Object(); // Initialize CHits and MHits as arrays postObject.CHits = []; postObject.MHits = []; // push some items into the arrays postObject.CHits.push(true); postObject.CHits.push(false); postObject.MHits.push(true); postObject.MHits.push(false); // serialize data to post // this is what you set as data property in for instance jquery ajax $.ajax({ //other params, content type etc type: 'POST', data: JSON.stringify(postObject), ... }); 

if your parameter is null, you should try to add the [FromBody] attribute and decorate the method with httppost

[HttpPost] public void Post([FromBody]Record record) { }

I am using this JSON {"CHits":[true,false],"MHits":[true,false]} in fiddler composer, and the controller does not get the data, shows NULL. Any idea?
OK, I forgot to pass the content negotiation stuff for the JSON. After adding the HTTP headers: Accept: application/json, text/javascript, /; q=0.01 Content-Type: application/json; charset=UTF-8 All works OK
