i'm trying to pass data from AngularJS to ASP.net MVC and is always getting null. Here's my code (only posting the essential, button, controller and c#:

HTML:

<a class="btn btn-grey btn-lg btn-block" ng-click="AddCar()">Save</a>

Controller

$scope.AddCar = function () {
            $http.post("Cars/AddCar", JSON.stringify($scope.new.JsonCar)).success(function (data) {
                Alert(ok)
            })

c#

public string AddCar(string JsonCar) 
        {
            try
           ....
        }

In JSON.stringify($scope.new.JsonCar) i'm getting this:

"{"Name":"FIAT 500","Description":"New car","MaxUserCapacity":5,"PhotoPath":"none"}"

What i'm doing wrong?

Pass your object directly as an object rather than stringifying it. As it's being passed right now, it's a string, not an object that can properly be deserialized.

$http.post("Cars/AddCar", $scope.new.JsonCar).success(function (data) {
            Alert(ok)
        })

Create a Car object that matches your payload. The serializer will handle your JSON object for you.

public Car AddCar(Car car) 
    {
        try
       ....
    }

My assumption is that at some point you are deserializing your string into an object regardless. This just saves you that extra step.

Perfect! Happy i could help. – David L Dec 14 '14 at 1:48
    
it works, because now it sets the contentType:"application/json" – VahidN May 1 at 9:21

Remove the JSON.stringify, your object is already JSON.

Add a [FromBody] attribute:

 public string AddCar([FromBody]string JsonCar) 
    {
        try
       ....
    }

The [FromBody] attribute tells MVC to get the value of the object from the body of the HTTP request. – Prathap Kudpu Apr 17 at 15:30
