{
    num: "1"
},
{
    num: "2"

Answer 1

If you are making your httpPost request and passing json object in your request body

Set

contentType:"application/json"

and in data use JSON.stringify(yourJson);

Something like this:

    $(function () {
    var youJsondata = {num :"2",num:"3"};
    $.ajax({
        type: "POST",
        data :JSON.stringify(youJsondata),
        url: "http://localhost:8082/api/Values/emptycardlist",
        contentType: "application/json"
    });
});

You api method should look something like this:

[HttpPost]
Route("api/Values/emptycardlist")
public HttpResponseMessage EmptyCardList([FromBody] JObject jobject){
   dynamic numList = jobject;
}

You api method should look something like this:

[HttpPost]
Route("api/Values/emptycardlist")
public HttpResponseMessage EmptyCardList([FromBody] dynamic dynObject){
    if(dynObject.Type == "Array") {
        // Handle list
    }

    // Handle response
}
