Question

I have the following class which is creating data access functions for Customers from my DB:

    public static Customer Get(int ID)
    {
        KezberPMDBDataContext db = new KezberPMDBDataContext();
        return (from p in db.Customers
               where p.CustomerID == ID
               select p).FirstOrDefault();
    }

    public static bool Remove(int ID)
    {
        Customer c = Get(ID);
        if (c != null)
        {
            KezberPMDBDataContext db = new KezberPMDBDataContext();
            db.Customers.DeleteOnSubmit(c);
            db.SubmitChanges();
            return true;
        }

        return false;
    }

I will be creating more classes, ex, Employees, that will need exactly the same functionality, just with the Employee class.

Is there some way I could avoid code duplication and use templates / generics in some way?

Thanks

EntityFramework 4.3 and 5’s DbSet class has a Find method that does exactly what your Get method does, and a Remove method that does sort of what your Remove does (it accepts an object and not an id).
