DataTable select record in ASP.Net

My data table have following columns

ID     employee     age     city    zip   ........

I want to use select to get only those records where age >= 25 and zip = "10001"

So how to use SELECT on datatable for these two criteria?

We can also use DataView, check this

DataView view = new DataView();
view.Table = dataTable;
view.RowFilter = "age >= 25 AND zip = '10001'";

Now your view will have only those records which matches your criteria.
