Object as a parameter for an action controller?

Question

Is it possible for an action controller to accept a literal object. For example, I have several views in which I would like to post various models from to a single controller th

Answer 1

Recently I faced the same issue and resolved it as below:

Step 1: From javascript pass 2 parameter :

First, pass model name as String for identification which model is coming

Second, Pass data from javascript using JSON.stringify(data). where your data can be from Model1, Model2 , Model3 etc.

Step2: In your controller:

[HttpPost]
public ActionResult ProcessModel(string modelName, string anyModel)
{
   switch(modelName)  {
      case "Model1":
             var modelValue= JsonDeserialize(anyModel);
              // do something 
           break;
     case "Model2": 
            var modelValue= JsonDeserialize(anyModel); 
            // do something
           break;
    }
}

You Need One method like below:

public T JsonDeserialize(string jsonModel){
return JsonConvert.DeserializeObject(jsonModel, jsonSettings);
}

JsonConvert need namespace "Newtonsoft.Json".

You also need to declare jsonSettings as below

         JsonSerializerSettings jsonSettings= new JsonSerializerSettings
    {
        TypeNameHandling = TypeNameHandling.All,
        DefaultValueHandling = DefaultValueHandling.Ignore
    };

This solution is kind of workaround. There is one more solution. you can check that also: How can I make a Controller Action take a dynamic parameter?

Hope this helps.
