将复杂数据发布到MVC 4

Question

I am pretty new to MVC 4 and I am trying to get my controller to recieve the post data from the request. It is pretty large and complex. Here is a snippet:

Customer.attribute[0].name=TriggerValue
Customer.attribute[0].value=451.51

Firebug shows the url encoded like this:

Customer.attribute%5B0%5D.name=TriggerValue&Customer.attribute%5B0%5D.value=451.51

These data points are posted to to the page, but I am unsure how to get the controller to receive it.

I've done the following with no avail:

// the get call 
public virtual ActionResult Alert()

Get works fine when you hit the page w/o sending post data so the page works.

// the post call?
[HttpPost]
public virtual ActionResult PriceAlert(PostData postdata)

for the model postData I have all the elements as strings or ints, or another class for the attribute one i did this:

public class customer
{
 ...
 public List<AlertAttribute> attribute { get; set; }
...
}
public class AlertAttribute
{
    public string name { get; set; }
     public string value { get; set; }
}

I have even tried the below and it also doesn't hit it.

[HttpPost]
public ActionResult PriceAlert(FormCollection fc)

Not sure if you need this or not, but when using firebug and looking at the post request the content information is as follows:

Content-Length  2313
Content-Type    application/x-www-form-urlencoded

EDIT: To make this more manageable, I have reduced the post values to try and create a simple posting request.

Model:

public class PostData
{
        public string BottomAd { get; set; }
        public string BottomAdLink { get; set; }
        public string BottomRandID { get; set; }


}

Controller:

    public virtual ActionResult PriceAlert()
    {
        return View();

    }

    [HttpPost]
    public virtual ActionResult PriceAlert(PostData postdata)
    {
        return View();

    }

    [HttpPost]
    public ActionResult PriceAlert(FormCollection fc)
    {
        return View();

    }

Post Request:

BottomAd=test&BottomAdLink=test&BottomRandID=test

Answer 1

Post:

Attributes[0].name=TriggerValue
Attributes[0].value=451.51

Note that indexes must start at 0 and be sequential, if you only post 0,1 and 5, then 5 will be missed because MVC stops binding lists once there is a gap in the sequence.

ViewModel:

public class CustomerVM
{
  List<NameValueVM> Attributes {get;set;}
}

public class NameValueVM
{
  public string Name {get;set;}
  public decimal Value {get;set;}
}

Controller Action:

public class CustomerController
{
    public ActionResult Save(CustomerVM vm)
    {
        //vm.Attributes should have one item in it

    }
}
