You can use Linq or Extension methods. This gives you SQL like interface and makes code readable

Example:
// Fill the DataSet.
DataSet ds = new DataSet();
ds.Locale = CultureInfo.InvariantCulture;
FillDataSet(ds);

DataTable products = ds.Tables["Product"];

IEnumerable productsQuery =
    from product in products.AsEnumerable()
    select product;

IEnumerable largeProducts =
    productsQuery.Where(p => p.Field<string>("Size") == "L");

Console.WriteLine("Products of size 'L':");
foreach (DataRow product in largeProducts)
{
    Console.WriteLine(product.Field<string>("Name"));
}
