ASP.NET - from DataRow how to split the bunch of data and render using Viewmodel

 foreach (DataRow dr in ds.Tables[0].Rows)
            {
                Viewmodel.responsemodel.Add(new responsemodel
                {
                    Summary = (string)dr["SUMMARY"]
                });




            }

This has data like name,mobile number etc for each user, I should be able to split inside that pick a string to render it

var list = Summary.split(",".ToCharArray());

I think this is what you are after if you intend to parse the contents of Summary based on some sort of delimiter.
