Question

How can I add a dynamic key to an anonymous List such as the mydatetime below:

DateTime myDateTime = DateTime.Parse(datepickerval, ukCulture.DateTimeFormat);
        var qid = (from p in db.Vw_INTERACTPEOPLE
                   select p
                   );

        var AvilList = new List<object>();
        var ddate = myDateTime.DayOfWeek.ToString().Substring(0, 3) + "Jul" + myDateTime.Day;
        foreach (var q in qid)
        {
            AvilList.Add(
                new
                {// Availability
                    Name = q.Fullname,
          here  >>> ddate = "Some Test"
                });

As adam says above there is no way to do this using Lists, however since the Slickgrid is expecting a Json return, I simply built the string in .net then returned it via the JavaScriptSerializer serializer, then in the code behind simply used eval to de-serialize back into an array.
