System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();


var s = @serializer.Serialize(Model);

var s = { "Name":"a","Id":1};

var s = @HTML.Raw(serializer.Serialize(Model));

public static MvcHtmlString ToJson(this HtmlHelper html, object obj)
  JavaScriptSerializer serializer = new JavaScriptSerializer();
  return MvcHtmlString.Create(serializer.Serialize(obj));
