Create New Class for Combine Class:

public class BadgeVoleModel
{
    public List<Badge> BadgeList = new List<Badge>();

    public List<VoleType> VoleTypeList = new List<VoleType>();
}

Create Method (return string) for handle get data from DataContext and populate data to BadgeVoleModel, and call from Controller that method.

    public string GetData()
    {
        var data = new Models.BadgeVoleModel();

        data.BadgeList = db.Badges.ToList();
        data.VoleTypeList = db.VoleTypes.ToList();

        var result = Newtonsoft.Json.JsonConvert.SerializeObject(data);

        return result;
    }

And for Deserialize Data:

    public Models.BadgeVoleModel DeserializeData(string data)
    {
        var result = Newtonsoft.Json.JsonConvert
                    .DeserializeObject<Models.BadgeVoleModel>(data);

        return result;
    }
