name = ds.Tables.Add("Customers");
name.Columns.AddRange(new DataColumn[] {
            new DataColumn("LastName", typeof(string)),
            new DataColumn("FirstName", typeof(string)),
            new DataColumn("ID", typeof(Int32))});
name.Rows.Add(new object[] {
            "Fielding",
            "William",
            0});
