new        1.2  2.1  1.7
  
"CN< 1.6 AND DS >1.5"

DataTable has a sort interface:

C#

mydatatable.DefaultView.Sort = "pname asc";

EDIT:
Try the following :

C#

DataRow[] rows1=mydatatable.Select("CN< 1.6 AND DS >1.5");

Solution 2

XML

DataView dv = dt.DefaultView;
dv.RowFilter = "CN < 1.6 AND DS > 1.5";
DataTable dt2 = dv.ToTable();
dv.RowFilter = "NOT(CN < 1.6 AND DS > 1.5)";
DataTable dt3 = dv.ToTable();
dt2.Merge(dt3);
dt = dt2;
dv = null;
dt2 = dt3 = null;
