Key Topics

Updating Records

Example

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        using (var context = new MyDbContext())
        {
            var employee = context.Employees.FirstOrDefault(e => e.Name == "John Doe");
            if (employee != null)
            {
                employee.Department = "Finance";
                context.SaveChanges();

                Console.WriteLine("Record updated successfully.");
            }
        }
    }
}

Explanation: This example retrieves a specific employee record, updates the department, and calls SaveChanges() to persist the changes.

Key Takeaways

  • Retrieve the entity to be updated, make the changes, and call SaveChanges().
  • EF Core automatically tracks changes to entities.
