            var cr = (from c in data.uvw_crossCustomerProducts

            List<object> tList = new List<object>();

            tList = (from c in data.uvw_crossCustomerProducts
                     select new { c.CustomerCode, c.ProductCode }).ToList<object>();


            return tList;
        }
    }
}

tetapi menampilkan pesa error sbb, bagaimana yang konversi yang benar ???:

cannot convert from 'System.Linq.IQueryable<AnonymousType#1>' to 'System.Collections.Generic.IEnumerable<object>'  

Anda bisa mencoba seperti ini:

var cr = (from c in data........)

List<object> tlist = new List<object>();

foreach (uvw_crossCustomerProduct cp in cr)

{

           tlist.Add(new object {CustomerCode = cp.CustomerCode, ProductCode = cp.ProductCode});

}

 return tList;

Semoga membantu.
