Question

I have following JSON saved in menu.json file:

       {
          "menu": {
                    "menuitems": [
                     {
                          "label": "Account",
                          "listview": "Account List"
                      },
                      {
                          "label": "Documents",
                          "listview": "Document List"
                      }
                                ]
                  }
       }

I have written this data to the file manually.I retrieve this data using following function:

        public ActionResult GetFromFile(string path)// path points to the menu.json file
       {
          StreamReader sr = new StreamReader(path);
          string filedata = sr.ReadToEnd();
          Menu menu = JsonSerializer.DeserializeToString<Menu>(filedata);
          return Json(menu, JsonRequestBehavior.Allowget);

       }

When I get the response as menu , I am not able to get it separated in the class fields. moreover, I have a single class and so how do I store my json file data to this class?? Will there be any modifications in the class structure? My Menu Class is as follows:

    public class Menu

    {
       public string Label {get;set;}
       public string Listview {get;set;}
   }

The serialization has an extra, unnamed container above menu. Your class structure needs to look like:

public class container
{
    public menu menu { get; set; }
}

public class menu
{
    public menuitem[] menuitems { get; set; }
}

public class menuitem
{
    public string Label { get; set; }
    public string Listview { get; set; }
}

And to deserialize, you can use:

JavaScriptSerializer js = new JavaScriptSerializer();
StreamReader sr = new StreamReader("menu.json");
string filedata = sr.ReadToEnd();
var menus = js.Deserialize<container>(filedata);
