Find implemented types from Generic interface in c#

public class AccountCreatedEvent : EventBase{}   

 public class AccountHandler : IEventHandler<AccountCreatedEvent>
    {
        public void Handle(AccountCreatedEvent event)
        {
        }
    }

This is a handler class and I want to get this class with c# code. I want to get list of implemented classes from IEventHandler type.

public class Account
{
    public void OnAccountCreated(EventBase accountCreatedEvent)
    {            
        var handler = typeof(IEventHandler<>);            
        var events = AppDomain.CurrentDomain.GetAssemblies()
            .SelectMany(s => s.GetTypes())
            .Where(p => denormalizer.IsAssignableFrom(p) && denormalizer.IsGenericType);

    }
}

But var events is returning

 {Name = "IEventHandler`1" FullName = "Project1.IEventHandler`1"}
