Get all tracked entities from a DbContext?

Question

Many of the tables in my database need to have a \"DateCreated\" and \"DateModified\" column. I want to update these columns whenever SaveChanges() is called.

Answer 1

I think you can use the ChangeTracker for this:

public class MyContext : DbContext
{
    //...

    public override int SaveChanges()
    {
        foreach (var dbEntityEntry in ChangeTracker.Entries())
        {
            dbEntityEntry.Entity.UpdateDates();
        }
        return base.SaveChanges();

    }
}
