Delegates and Events as component technology for GoF Observer pattern ?

I am a college student trying to build a small Windows Application in Visual Studio 2005.

Business Context:

Simulation of Computer science department that contains faculty, students, courses, programs, registration process etc.

My Question:

One aspect of the project requires me to simulate students enrolling/dropping classes, and the automatic notification to a faculty member when an enrollment is reached. Is delegates and events the best way to implement this in C# ? Does this involve a lot of code? Any good implementation strategies on this with respect to C# ?

Is there any good component technology that can be readily used to capture the Gang of Four Observer design pattern that can be applied to the above problem ?

Thanks.

oops. forgot... We need to set things in motion... Here is where we call the CountToTen method, notice that we get a message box because once it hits ten, the OnCountedToTen event is raised.

private void button_Click(object sender, System.EventArgs e)
{
numberCounter.CountToTen();
}

So if you wanted to use events then you could raise an event when a student is enrolled. Then another class can handle that event and do what it needs to do. Since this is homework I don't want to give away too much, but you could definitely use events in your situation (which really is pretty much the observer pattern).

CORRECTION:

The line that reads:
the observer notifies all of the "subjects" when something interesting happens

should read:
the "subject" notifies all of the "observers" when something interesting happens.

Sorry about the confusion.
