Passing json list to MVC 3

Question

I am trying to submit this with Ajax to a MVC3 controller:

    var params = {
        \'productId\': productId,
        \'list\': []
    };

    $.each($(\'.

ASP.NET MVC 3 includes built-in JSON model binding.

So create simple POCOs which matches the JSON your attempting to submit:

public class ProductJsonModel
{
   public int ProductId { get; set; }
   public ProductSpecificationJsonModel[] @List { get; set; }
}

public class ProductSpecificationJsonModel
{
   public int SpecificationId { get; set; }
   public int ArticleId { get; set; }
   public double Price { get; set; }
   public int Stock { get; set; }
   public int StockCount { get; set; }
   public int Weight { get; set; }
   public bool Visible { get; set; }
}

Then accept that in your action:

[HttpPost]
public Boolean Save(ProductJsonModel model)

As long as the property names in the JSON object match the property names in the POCO's, MVC will bind for you.

Also - you should serialise the JSON using .stringify or something similar, and set the contentType of the $.ajax object accordingly.
