What does the 'friend' modifier do in VB.NET?
Why is it the default modifier for GUI components in Visual Studio?
回答1:
friend in VB.Net is the same as internal in C#, it means that it can be accessed anywhere in the same assembly, but not from other assemblies.
I think it's a sensible default since I would say that normally one assembly should not be using another assembly's GUI controls (unless it's a class library or similar that is built for the purpose).
回答2:
Friend is available in VB:
The Friend (Visual Basic) keyword in the declaration statement specifies that the elements are accessible from within the same assembly,
From here
I believe the c# version is internal
