Can someone explain me the behaviour of the following line in VB
Return Not (s Is Nothing)
I am looking to translate this in C# and i am not sure about those negation and do not understand the conditions.
thanks for the quick answer. I understand those negation better now.

A:
In C# this would be
return s != null
A more direct transaltion is
return !(s == null)
but that would be odd looking in C# so the original translation is prefered.

I also find the fact that it returns a boolean confusing. I would have expected it to mean "return s if it isn't null" instead of "return is s null or not"

DrDro, I can see how you might see it that way, but what would it return if s is null? It has to return something. If it would just return null if s was null then that just be `return s`

Just FYI, in “idiomatic” VB, this would rather be written as:
Return s IsNot Nothing
