1. I want to change last number of my every "No" for all students (who is born between 1996 and 1998) to 0, for example. (from 160456 to 1604560)


2. I want to delete data for students whos "No" first 2 numbers is 14, for example. (user2.No = 143457;)
   How to find data only by 1 or more numbers?

I'm using Linq:

using System.Linq;

using Db4objects.Db4o.Linq;

My database look like this:

 User user1 = new User();

    user1.Name = "Bob";

    user1.Surname = "Topson";

    user1.No = 160456;

    user1.Birth = new DateTime (1998, 5, 12);



 User user2 = new User();

    user2.Name = "Rob";

    user2.Surname = "Simpson";

    user2.No = 143457;

    user2.Birth = new DateTime (1996, 8, 4);

my user.cs code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;



namespace db4o

{

    class User

    {

        public string Name { get; set; }

        public string Surname { get; set; }

        public int No { get; set; }

        public DateTime Birth { get; set; }

    }

}
