JSON.NET deserializing a multidimensional array?

Question

I am passing (or well trying to!) a JSON object to my codebehind.

This is the JSON object:

[
    {
        "testLaag":{
            "layer_zindex":1,
            "layer_type":1,
            "layer_width":1,
            "layer_height":1,
            "layer_offset_left":1,
            "layer_offset_top":1,
            "layer_html":1,
            "layer_fontcolor":1,
            "layer_fontsize":1,
            "layer_rotation":1,
            "layer_color":1,
            "layer_name":1,
            "layer_fontFamily":1
        },
        "testLaag2":{
            "layer_zindex":2,
            "layer_type":2,
            "layer_width":2,
            "layer_height":2,
            "layer_offset_left":2,
            "layer_offset_top":2,
            "layer_html":2,
            "layer_fontcolor":2,
            "layer_fontsize":2,
            "layer_rotation":2,
            "layer_color":2,
            "layer_name":2,
            "layer_fontFamily":2
        }
    }
]

The code from the code behind:

string data = "[" + Request.Form["layers"] + "]";
JsonSerializerSettings settings = new JsonSerializerSettings();
settings.TypeNameHandling = TypeNameHandling.All;
List<Laag> layers = JsonConvert.DeserializeObject<List<Laag>>(data, settings);

foreach (Laag laag in layers)
{
    Response.Write(laag.layer_name);
}

And here is my class:

public class Laag
{
    public int layer_zindex {get; set;}
    public int layer_type { get; set; }    
    public double layer_width { get; set; }
    public double layer_height { get; set; }
    public double layer_offset_left { get; set; }
    public double layer_offset_top { get; set; }
    public string layer_html { get; set; }
    public string layer_fontcolor { get; set; }
    public double layer_fontsize { get; set; }
    public double layer_rotation { get; set; }
    public string layer_color { get; set; }
    public string layer_name { get; set; }
    public string layer_fontFamily { get; set; }
}

It is currently driving both me and my colleague nuts. All we want, is to have both "laag" objects in a List object. JSON and how to process are quite new to both of us, so we're probably missing something incredibly stupid though.

Thanks in advance,

Create another wrapper class

public class wrapperOfLaag{
     public List<Laag> listLag;
}

and then try

string data = "[" + Request.Form["layers"] + "]";
JavaScriptSerializer ser = new JavaScriptSerializer();
wrapperOfLaag p = ser.Deserialize<wrapperOfLaag >(data);
