Question

The assignment states

“Write a program to print only even numbers between 6 and 16 using
events.”

while in the class we only use CL applications just having a button wouldnt work. So I thought about using an if than statement that would raise an event if CurrentNumber is even with mod 2 as current number is declared as 6

        While CurrentNumber < 17
        If CurrentNumber Mod 2 Then
            RaiseEvent Even()
            CurrentNumber = CurrentNumber + 1
        Else
            CurrentNumber = CurrentNumber + 1
        End If
    End While

But how would I handle the event to console.writeline(CurrentNumber) basically what I need to do is to make a program that prints even numbers using events how I was trying to solve the problems was to invoke in event if the number is even that shows the current number

Answer 1

I think you are on the right track. What if you were to build a class that only had one purpose–to count numbers and raise events when an even or odd number occurs? Let’s say this class is called Counter.

Next, what if your Program class had an instance of the Counter class and had an event handler only for the Even event? The handler could perform a Console.WriteLine() each time an even number occurs.
