Use of delegates and invoke to call different sub depending on some variable - vb.net

Question

I would like to organize a class as follows (pseudocode)
Class MyClass
sub New(MethodEnabled as integer)
if MethodEnabled = 0
make MyMethod() to be Sub0()
else
make MyMethod() to be Sub1()
end if
end sub
sub MyMethod()
invoke(either sub0 or sub1 depending on "MethodEnabled" value)
end sub
sub Sub0()
some code here
end sub
sub Sub1()
some code here
end sub
End Class
What I wish is to have the sub "MyMethod()" to invoke (or "to be") either Sub0() or Sub1(), depending on how the class was constructed (either with MethodEnabled=0, or MethodEnabled=1).
I gather intuitively that I can do that by using delegates and invoke, but I am not much clear on how to actually do it, in practice.
Can anybody show me how I can possibly do this in the most elegant way. C# of VB.NET examples would be equally great. Thank you!

Answer 1

You need to either declare a delegate type or use System.Action, and then use an instance of that delegate type:
Class [MyClass]
Private Delegate Sub myDelegate()
Private myDelegateInstance As myDelegate
'or you could just leave out 'myDelegate' and use 'System.Action'
Sub New(ByVal MethodEnabled As Integer)
If MethodEnabled = 0 Then
myDelegateInstance = AddressOf Sub0
Else
myDelegateInstance = AddressOf Sub1
End If
End Sub
Sub MyMethod()
myDelegateInstance()
End Sub
Sub Sub0()
'some code here
End Sub
Sub Sub1()
'some code here
End Sub
End Class
