Answer 1

Private Delegate Sub numManip()

Sub Main()
Dim evennumber As numManip
Dim allNumbers As [Delegate]
evennumber = New numManip(AddressOf Even)
allNumbers = [Delegate].Combine(evennumber)
allNumbers.DynamicInvoke()
End Sub

Sub Even()
Console.Clear()
Dim counter As Integer = 2
Console.WriteLine("Even Numbers")
Console.WriteLine("Please Enter the Number you Wish to End at: ")
Dim number As Integer = Console.ReadLine()
Console.Clear()
Console.WriteLine("All Even Numbers From 6 to " & number)
Do Until counter > number
Console.WriteLine(counter)
counter += 2
Loop
Console.WriteLine("Press Enter to Continue...")
