Accessing an internal .NET class with public constructors

[YohanShminge]

Hi All,

Is there a way in LabVIEW to access the public constructors of an internal C# class?  For example, I have this bit of code inside a DLL (which I can't modify):

namespace IODevice_X
{
      class PlugIn : IOPlugin

Now within this (internal) PlugIn class I have several public constructors, but it seems that without explicitly writing "publig class PlugIn : IOPlugin" these constructors don't show up in the list inside LabVIEW 8.2.  The strange thing is that another programmer I'm working with is using the constructors from the PlugIn class DLL without any trouble.  Of course, he's creating his interface with C# and Visual Studio.

So the question is how (if possible) can I access public constructors within an internal class?

Thanks!

Hi,

Which "list inside LabVIEW" are you referring to?  Are you trying to call the constructor through a Constructor Node or access it some other way?  Without explicitly labeling the class as "public", the class will not be exported, and will not be automatically populated in LabVIEW.  You might be able to manually type everything in, but it will depend on how you are trying to access this class.

Hi Donovan,

Thanks for your reply!  Yes, the list I'm referring to is the list of objects you get within the Constructor node.  Is there some other way to access .NET classes?  What do you mean by being able to "manually type everything in"?

Thanks,
Yohan

Hi Yohan,

I forgot you were using the constructor and not a function.  No, there are not other ways to access the .NET classes.  The only thing I can think of that may let you access this constructor without changing the assembly itself is to create another assembly that is public and accesses the class you want.  Without the class being declared as public, you will not be able to access the constructor in LabVIEW.

Alright, well at least now I know!  Thanks for your help!
