I am trying to pass a class variable as an optional parameter to a function. But it requires a default value. What could I set the default value for the optional class variable.
Private Function SaveFruit(Optional byval tempBanana As BananaClass = ?)
Private Function SaveFruit(Optional byval tempBanana As BananaClass = Nothing) If tempBanana Is Nothing Then tempBanana = OtherDefaultBanana ..... End Function
As shown in the example above you have to check if it's
Nothing with the
Is-operator before you can use it, otherwise you will get a
NullReferenceException. Then you can either assign another instance which already exists or one that you initialize now.
