posting JSON to MVC controller - String parameter is null

Question

I am intentionally trying NOT to use a binding in the controller parameter, so I have a controller that looks like:

 [HttpPost]
        public ActionResult Untyp

The function serializeArray creates a Javascript object with the form's key/value pairs. You don't want that, you want a single key/value with serializedformdata = (JSON string). Ie, like this;

var formelements = { serializedformdata: JSON.stringify($('#form').serializeArray()) };

This passes the raw JSON string to the controller's parameter. You can use the JavaScriptSerializer to get the object on the server:

var obj = (List<Dictionary<string,string>>)new JavaScriptSerializer().Deserialize(serializedformdata, typeof(List<Dictionary<string,string>>));
Dictionary<string,string> dict = obj.First();
string someval = dict["somekey"];
