Datatable根据多行排序

            DataTable dt = new DataTable();
            dt.Columns.Add("ID", typeof(int));
            dt.Columns.Add("Name", typeof(string));

            dt.Rows.Add(new object[] { , "lwolf" });
            dt.Rows.Add(new object[] { ,"kkkkk"});
            dt.Rows.Add(new object[] { ,"jim" });
            dt.Rows.Add(new object[] { ,"test" });

            DataTable dtCopy = dt.Copy();

            DataView dv = dt.DefaultView;
            dv.Sort = "ID";
            dtCopy = dv.ToTable();
