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[] { 12, "lwolf" });

            dt.Rows.Add(new object[] { 100,"kkkkk"});

            dt.Rows.Add(new object[] { 19,"jim" });

            dt.Rows.Add(new object[] { 1,"test" });



            DataTable dtCopy = dt.Copy();



            DataView dv = dt.DefaultView;

            dv.Sort = "ID";

            dtCopy = dv.ToTable();
