QuestionGetting the Excepption ExceptionType Newtonsoft.Json.JsonSerializationException in my Web API Pin
indian14311-May-17 8:56

Hi All,

I am trying to return a DataSet that has 6 table to a cshtml file from Web Api, that DataSet is created by using the Entities from Entity Framework the reason I am returning the DataSet is I am converting the Entity Collections as Tables and wrapping them in a DataSet and returning that.

But I am getting the following Exceptions, anybody can please help me in fixing it? Here is my Get method Code:
        public DataSet Get()
        {
            DataSet dsAllListsOfForm = new DataSet();
            dsAllListsOfForm.Tables.Clear();

            dynamic objCollection; DataTable table;
            using (AppDevSecEntities ctx = new AppDevSecEntities())
            {
                objCollection = (from c in ctx.Departments orderby c.DepartmentName select c).AsQueryable();
                table = Common.ConvertToDataTable<Department>(objCollection);
                dsAllListsOfForm.Tables.Add(table);

                objCollection = (from c in ctx.FunctionalCatagories orderby c.FunctionalCatagoryName select c).AsQueryable();
                table = Common.ConvertToDataTable<FunctionalCatagory>(objCollection);
                dsAllListsOfForm.Tables.Add(table);

                objCollection = (from c in ctx.BusinessUnits orderby c.BusinessUnitName select c).AsQueryable();
                table = Common.ConvertToDataTable<BusinessUnit>(objCollection);
                dsAllListsOfForm.Tables.Add(table);

                objCollection = (from c in ctx.Locations orderby c.LocationName select c).AsQueryable();
                table = Common.ConvertToDataTable<Location>(objCollection);
                dsAllListsOfForm.Tables.Add(table);
            }

            return dsAllListsOfForm;
       }

Any help/suggestion is going to be very helpful, I am really new to the MVC and FrontEnd tools because I was working with Integrations for quite a While, thanks in advance.

Thanks,

Abdul Aleem
