            var UserList = repositoryUser.GetUserDetails();
            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[5] { new DataColumn("ID", typeof(long)),
            new DataColumn("Name", typeof(string)),
            new DataColumn("Age", typeof(int)),
            new DataColumn("Address", typeof(string)),
            new DataColumn("DOB", typeof(string)),
            foreach (var x in UserList)
                dt.Rows.Add(x.ID, x.Name, x.Age, x.Address, x.DOB);

            Response.Buffer = true;
            Response.Charset = "";
            Response.ContentType = "application/text";

            StringBuilder sb = new StringBuilder();
            for (int k = 0; k < dt.Columns.Count; k++)
                //add separator
                sb.Append(dt.Columns[k].ColumnName + ',');
            //append new line
            for (int i = 0; i < dt.Rows.Count; i++)
                for (int k = 0; k < dt.Columns.Count; k++)
                    //adding separator
                    sb.Append(dt.Rows[i][k].ToString().Replace(",", ";") + ',');
