using System;
using System.Linq;

class Program
{
    static void Main()
    {
        using (var context = new MyDbContext())
        {
            var employees = context.Employees
                .Where(e => e.Department == "IT")
                .ToList();

            foreach (var employee in employees)
            {
                Console.WriteLine("Name: " + employee.Name);
            }
        }
    }
}

Explanation: This example filters employees based on the department IT using the Where method.

Key Takeaways

  • Use the Where() method to apply conditions for filtering.
  • Combine multiple conditions with logical operators like && and ||.
