Generic object (json) catcher in Mvc controller?

Question

Is it possible to create a generic Mvc controller that catches any simple Json object from a web page post and can then be interrogated for keys/values, eg

public JsonResult SaveData(Dictionary<String, Object> rs)
        {
        PersonObject obj= new PersonObject();
        foreach (string Key in rs.Keys){
           if (Key == "name")
               obj.Name=rs[Key];
      }       

    }

My web page does something like this :
    var obj={"name" : "blah", "age": 38, "gender" : "lady"};
    $.post('SaveControler/saveData', obj, function(d){});

I basically don't want to keep constructing custom view models for each entity, just have some generic code for each controller action that can use reflection to populate objects.

have you tried this ? https://stackoverflow.com/a/1212115/7262120 — Arvind Maurya, Feb 14 '19 at 06:34

Controller :

public ActionResult About(string rs)
        {

            var values = JsonConvert.DeserializeObject<Dictionary<String, Object>>(rs);
            return Json(values);
        }

Jquery:

var obj = { "name": "blah", "age": 38, "gender": "lady" };
            $.post('@Url.Action("About")', { rs: JSON.stringify(obj) }, function (d) {
                debugger;
            });

You can receive JSON as object and then deserialize it by type:

public ActionResult About(object rs)
{
   string JsonString = rs.Tostring();  
   var _PersonObject =  JsonConvert.DeserializeObject<Person>(JsonString);
}
